POLYZEN DEVICES Polymer Protected Zener Diode PolyZen devices are polymer-enhanced, precision Zener diodes. They offer resettable protection against multi-Watt fault events without the need for multi-Watt heat sinks. The Zener diode used for voltage clamping a PolyZen device was selected due to its relatively flat voltage vs. current response. This helps improve output voltage clamping, even when input voltage is high and diode currents are large. An advanced feature of the PolyZen device is that the Zener diode is thermally coupled to a resistively non- linear, PPTC (polymer positive temperature coefficient) layer. This PPTC layer is fully integrated into the device and is electrically in series between V and the diode IN clamped V . OUT This advanced PPTC layer responds to either extended diode heating or overcurrent events by transitioning from a low to high resistance state, also known as tripping. A tripped PPTC will limit current and generate voltage drop. It helps to protect both the Zener diode and the follow-on electronics and effectively increases the diodes power handling capability. The polymer-enhanced Zener diode helps protect sensitive portable electronics from damage caused by inductive voltage spikes, voltage transients, incorrect power supplies and reverse bias. These devices are particularly suitable for portable electronics and other low-power DC devices. BENEFITS APPLICATIONS Stable Zener diode helps shield downstream DC power port protection in portable electronics electronics from overvoltage and reverse bias DC power port protection for systems using barrel Trip events shut out overvoltage and reverse bias jacks for power input sources Internal overvoltage and transient suppression Analog nature of trip events helps minimize damage DC output voltage regulation from upstream inductive spikes Tablet PCs and portable electronics Minimal power dissipation requirements Single component placement FEATURES Overvoltage transient suppression Multi-Watt power handling capability Integrated device construction Stable V vs. fault current Z Time delayed, overvoltage trip RoHS compliant Time delayed, reverse bias trip Halogen free (refers to: Br 900ppm, Cl 900ppm, Br+Cl 1500ppm) RoHS Compliant, ELV Compliant Specifications subject to change without notice. 2016 Littelfuse, Inc. 27PolyZen Devices Polymer Protected Zener Diode Figure PZ1 Typical Application Block Diagram Power Supply (External or Internal) Protected Electronics GND 2 V IN PolyZen 1 Device + V OUT 3 R Regulated LOAD Output Protected Downstream Electronics Table PZ1 Electrical Characteristics (Performance ratings 25C unless otherwise specified) V (V) V I Z INT MAX FLT MAX I Test Test HOLD I 20C R R V Current I Voltage Zt Typ 1MAX INT MAX FLT MAX Part Number Min Typ Max (A) (A) ( ) ( ) (V) (A) (A) (V) ZEN056V130A24LS 5.45 5.60 5.75 0.10 1.30 0.12 0.16 24 3 +10/-40 +24/-16 ZEN059V130A24LS 5.80 5.90 6.00 0.10 1.30 0.12 0.15 24 3 +6/-40 +24/-16 ZEN065V130A24LS 6.35 6.50 6.65 0.10 1.30 0.12 0.16 24 3 +6/-40 +24/-16 ZEN098V130A24LS 9.60 9.80 10.00 0.10 1.30 0.12 0.16 24 3 +3.5/-40 +24/-16 ZEN132V130A24LS 13.20 13.40 13.60 0.10 1.30 0.12 0.16 24 3 +2/-40 +24/-16 ZEN164V130A24LS 16.10 16.40 16.60 0.10 1.30 0.12 0.16 24 3 +1.25/-40 +24/-16 ZEN056V230A16LS 5.45 5.60 5.75 0.10 2.30 0.04 0.06 16 5 +5/-40 +16/-12 ZEN065V230A16LS 6.35 6.50 6.65 0.10 2.30 0.04 0.06 16 5 +3.5/-40 +16/-12 ZEN098V230A16LS 9.60 9.80 10.00 0.10 2.30 0.04 0.06 16 5 +3.5/-40 +16/-12 ZEN132V230A16LS 13.20 13.40 13.60 0.10 2.30 0.04 0.06 16 5 +2/-40 +20/-12 ZEN056V075A48LS 5.45 5.60 5.75 0.10 0.75 0.28 0.45 48 3 +10/-40 +48/-16 ZEN132V075A48LS 13.20 13.40 13.60 0.10 0.75 0.28 0.45 48 3 +2/-40 +48/-16 ZEN056V115A24LS 5.45 5.60 5.75 0.10 1.15 0.15 0.18 24 3 +10/-40 +24/-16 NEW ZEN056V130A16YM 5.35 5.60 5.85 0.10 1.30 0.110 0.160 14 3 +3/-40 +16/-12 NEW ZEN056V175A12YM 5.35 5.60 5.85 0.10 1.75 0.050 0.095 12 4 +3/-40 +12/-12 NEW ZEN132V130A16YM 13.20 13.40 13.80 0.10 1.30 0.110 0.160 14 3 +1/-40 +20/-12 NEW ZEN132V175A12YM 13.20 13.40 13.80 0.10 1.75 0.050 0.095 12 4 +1/-40 +20/-12 NEW ZEN056V130A24YC 5.35 5.60 5.85 0.10 1.30 0.110 0.170 24 3 +4/-40 +24/-16 NEW ZEN056V230A16YC 5.35 5.60 5.85 0.10 2.30 0.040 0.070 16 5 +3/-40 +16/-12 NEW ZEN056V260A16YC 5.35 5.60 5.85 0.10 2.60 0.040 0.055 16 5 +3/-40 +16/-12 NEW ZEN132V130A24YC 13.20 13.40 13.80 0.10 1.30 0.110 0.170 24 3 +1/-40 +24/-16 NEW ZEN132V230A16YC 13.20 13.40 13.80 0.10 2.30 0.040 0.070 16 5 +1/-40 +20/-12 NEW ZEN132V260A16YC 13.20 13.40 13.80 0.10 2.60 0.040 0.055 16 5 +1/-40 +20/-12 LS module height is 1.7mm typical.
