HBL5006 Series LED Shunt The HBL5006 Series are electronic shunts which provide a current bypass in the case of LEDs going into open circuit. LEDs are by nature quite fragile when subjected to transients and surge conditions. There are also many cases where high reliability of the LED lighting must be maintained such as in headlights, lighthouses, bridges, aircraft, runways www.onsemi.com and so forth. In these cases the low cost addition of the shunt device will provide full assurance that an entire string of LEDs will not extinguish MARKING should one LED fail open. The shunt device is also applicable to other DIAGRAMS loads where circuit continuity is required. The devices are designed to be used with LED string currents from 50 to 350 mA. 1 2 SOD323 HD CASE 477 M Features Protection for the Following IEC Standards: IEC 6100042 (Level 4) 12 SOD523 ISO 10605 56 CASE 502 Low ESD Clamping Voltage Automatically Resets Itself if the LED Heals Itself or is Replaced 1 2 ONState Voltage Typically 1.1 V SOD923 LD M CASE 514AB OFFState Current less than 1.0 A SZ Prefix for Automotive and Other Applications Requiring Unique XX = Specific Device Code Site and Control Change Requirements AECQ101 Qualified and M = Date Code PPAP Capable These Devices are PbFree and are RoHS Compliant Typical Applications HBL5006 LEDs where Preventive Maintenance is Impractical LED Headlights in Automobiles Automotive LED Applications Control LEDs with High Reliability Requirements Circuit ESD Crowbar Protection for Open Circuit Conditions Overvoltage Protection for Sensitive Circuits 1 + HBL5006 2 Apply heat sinking to pin 2 ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 5 of this data sheet.

If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. 2 1. Mounted onto a 2layer, 1000 mm per layer, 3 oz Cu, FR4 PCB with pin 2 connected to the heat sink and pin 1 only connected to a signal trace. The heat sinking must be connected to pin 2, which is the LED cathode connection. Normally this device would be mounted on the same copper heat sink and adjacent to the LED(s). If the LED(s) were to go open, then the HBL shunt would now dissipate the power using the same copper heat sink. Since the shunt has a voltage that is nominally 30% of the LED, then the power dissipation would be much lower, and easily handled by the same heat sink as the LED. 2 2. Mounted onto a 2layer, 50 mm per layer, 1 oz Cu, FR4 PCB. 3. Max operating temperature for DC conditions is 150C, but not to exceed 175C for pulsed conditions with low duty cycle or nonrepetitive. www.onsemi.com 2
