Product details
Overview
LBP01-0810B from STMicroelectronics is a bidirectional LED bypass protection device in SMB (DO-214AA) package, rated for 1 A DC on-state current, 8–15 V breakover voltage, and 24 A IEC 61000-4-5 surge immunity. It shunts current around open-circuit LEDs in high-reliability lighting strings where continuous operation is mandatory-e.g., automotive headlights and aircraft runway lights.
For engineers reviewing the LBP01-0810B datasheet, LBP01-0810B pinout, LBP01-0810B application, or LBP01-0810B equivalent, key selection criteria include bidirectional clamping behavior, 1 A steady-state current handling, SMB thermal resistance (100 °C/W on 1 cm² copper), IEC 61000-4-2/4-5 compliance, and compatibility with LED strings up to two series-connected devices.
Technical Context
The LBP01-0810B operates as a self-triggering bidirectional thyristor-based bypass switch. Its control circuit activates at 8–15 V (VBO), sustaining conduction above 200 mA holding current (IH) while limiting forward voltage to 1.3 V at 0.35 A and 1.5 V at 1 A.
It integrates robust silicon die designed for surge resilience: 30 kV peak pulse voltage (IEC 61000-4-2 contact discharge), 24 A repetitive 8/20 µs pulse current (IEC 61000-4-5), and dV/dt capability of 300 V/µs-enabling reliable fail-safe operation without external triggering or biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBO | 8–15 V: Breakover voltage range at which device triggers into low-impedance conduction to bypass failed LED. |
| IH | 200 mA: Minimum holding current required to sustain conduction after triggering-ensures stable shunt path during LED open fault. |
| Von @ 1 A | 1.5 V: Forward voltage drop at full-rated 1 A DC current-limits power dissipation to 1.5 W under worst-case bypass condition. |
| IPP | 24 A (8/20 µs): Peak surge current rating per IEC 61000-4-5-protects downstream LEDs from line transients. |
| Rth(j-a) | 100 °C/W (SMB, 1 cm² copper): Junction-to-ambient thermal resistance-defines maximum allowable ambient temperature for 150 °C max junction operation at 1 A. |
| dV/dt | 300 V/µs: Minimum rate-of-rise of voltage the device can withstand without false triggering-critical for noisy automotive/lighting bus environments. |
Pinout & Package
SMB (DO-214AA) surface-mount package with cathode-anode symmetry enabling bidirectional operation; no polarity marking required for functional installation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (both ends) | Bidirectional current path | Terminals are functionally interchangeable; device conducts in either direction once triggered above VBO. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional bypass switching | Enables single-device protection of AC-coupled or polarity-agnostic LED strings without external diodes or orientation constraints. |
| Self-triggering overvoltage clamp | Activates autonomously at 8–15 V without external control circuitry-reduces BOM count and PCB footprint vs. MOSFET+controller solutions. |
| IEC 61000-4-2/4-5 compliance | Withstands ±15 kV air / ±8 kV contact ESD and ±1 kV/24 A surge events-eliminates need for supplemental TVS in many lighting designs. |
| 1 A continuous current rating | Supports direct parallel connection across high-current LED strings (e.g., automotive headlight modules) without derating or heatsinking. |
Applications
| Automotive Headlights | Traffic Lights |
|---|---|
Use Scenario: LED arrays in adaptive front-lighting systems must remain illuminated even if one or more LEDs fail open. IC Role / Device Role / Timing Role: Bidirectional bypass switch that automatically reroutes current around open LEDs without interrupting string operation. Use Value: Prevents total headlight blackout-meeting UN ECE R112 safety requirements for continuous illumination during partial LED failure. | Use Scenario: Red/amber/green signal clusters deployed outdoors face frequent lightning-induced surges and thermal cycling. IC Role / Device Role / Timing Role: Surge-protected shunt element placed across individual LEDs or small sub-strings. Use Value: Maintains traffic signal visibility during LED failure while surviving repeated 24 A surges per IEC 61000-4-5. |
| Aircraft Runway Lights | Emergency Lighting Systems |
Use Scenario: High-integrity ground lighting must operate continuously during flight operations; LED failure cannot cause dark zones. IC Role / Device Role / Timing Role: Fail-safe bypass component mounted directly across each LED in series string. Use Value: Ensures ≥99.9% uptime by eliminating single-point LED failure mode-critical for FAA AC 150/5340-30E compliance. | Use Scenario: Battery-backed exit signs and corridor lighting require uninterrupted operation during power loss or LED degradation. IC Role / Device Role / Timing Role: Autonomous current-steering device that activates within nanoseconds of LED open-circuit detection. Use Value: Extends system lifetime beyond 10 years by preventing cascade failure and reducing maintenance frequency by >70%. |

FAQ
What is the triggering mechanism of the LBP01-0810B?
The LBP01-0810B uses an integrated bidirectional thyristor structure that triggers into conduction when voltage across its terminals exceeds the breakover range (8–15 V). No external gate drive or biasing is needed-it operates autonomously upon LED open-circuit failure.
Can LBP01-0810B be used across more than two LEDs?
No. Per ST's datasheet, the LBP01 series is specified for parallel connection across one or two LEDs only. Using it across three or more LEDs risks insufficient voltage margin for reliable triggering and may exceed VBO tolerance under normal operating conditions.
How does thermal performance differ between SMB and SOT23-5L packages?
The SMB package delivers 100 °C/W junction-to-ambient thermal resistance (with 1 cm² copper), supporting 1 A continuous current. The SOT23-5L version is limited to 0.35 A due to higher 140 °C/W thermal resistance-making SMB essential for high-power lighting applications.
Is LBP01-0810B compliant with automotive qualification standards?
LBP01-0810B meets IEC 61000-4-2 and IEC 61000-4-5 for surge/ESD immunity and operates from −55 °C to +150 °C, but ST does not specify AEC-Q100 qualification for this part. For automotive use, system-level validation per ISO 16750-2 is required.
