Product details
Overview
BZW06-376BH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode with a working stand-off voltage of 376 V, breakdown voltage of 418–462 V, and clamping voltage of 603 V at 1.3 A (10/1000 µs). It features AEC-Q101 qualification, low dynamic impedance, and sub-1 ps response time, deployed for automotive ESD and inductive load surge protection in powertrain control modules.
For engineers reviewing the BZW06-376BH datasheet, BZW06-376BH pinout, BZW06-376BH application, or BZW06-376BH equivalent, key selection criteria include its DO-204AC (DO-15) package, 175°C max junction temperature, 600 W peak pulse power rating, and AEC-Q101 qualification for automotive-grade reliability under fast transient stress.
Technical Context
The BZW06-376BH operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 418–462 V breakdown range at 1 mA test current. Its clamping action limits transients to ≤603 V at 1.3 A (10/1000 µs), with thermal resistance of 60°C/W (junction-to-lead) enabling sustained surge handling in constrained PCB layouts.
Designed for high-energy transient suppression, it delivers <1 µA leakage at 376 V, exhibits a 0.110 %/°C temperature coefficient on VBR, and maintains stable performance across –55°C to +175°C operating junction range-critical for under-hood automotive electronics exposed to thermal cycling.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ376A | Same VWM (376 V), lower PPK (600 W), but SMB package (surface-mount); no AEC-Q101 certification listed | Requires rework for SMT assembly; unsuitable for legacy through-hole automotive designs requiring AEC validation | Select only if board space constraints mandate SMT and AEC-Q101 is not required |
| P6KE376A | Same VWM/VBR range, same DO-15 package, but rated for 600 W at 10/1000 µs and lacks AEC-Q101 qualification | Acceptable for industrial non-automotive use; cannot be used in production automotive ECUs without additional qualification | Choose for cost-sensitive industrial applications where AEC-Q101 is not mandated |
Compared with SMBJ376A and P6KE376A, the BZW06-376BH uniquely combines DO-204AC through-hole compatibility, 600 W surge capability, and factory-certified AEC-Q101 qualification-making it the only drop-in solution for Tier 1 automotive suppliers requiring audit-ready compliance documentation.

FAQ
What is the maximum clamping voltage of the BZW06-376BH under a 10/1000 µs surge?
The BZW06-376BH has a maximum clamping voltage of 603 V when subjected to a 1.3 A peak pulse current with a 10/1000 µs waveform. This value is measured per JEDEC standards and ensures downstream ICs see limited overvoltage during standardized surge events. The BZW06-376BH achieves this while maintaining low dynamic impedance and minimal voltage overshoot due to its optimized silicon junction design.
Is the BZW06-376BH suitable for bidirectional signal line protection?
No-the BZW06-376BH is a unidirectional TVS diode, indicated by the absence of "B" suffix and presence of cathode band marking. For bidirectional protection, the BZW06-376BH's counterpart BZW06-376B must be used. The BZW06-376BH is intended for DC power rail protection where polarity is fixed, such as 12 V/24 V battery inputs in automotive ECUs.
Does the BZW06-376BH meet RoHS and halogen-free requirements?
Yes-the BZW06-376BH complies with RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. Its molding compound meets UL 94V-0 flammability rating, and lead finish uses pure tin plating conforming to J-STD-002 solderability standards. These attributes are confirmed in Taiwan Semiconductor's official BZW06 series datasheet revision K2105.
What is the junction-to-lead thermal resistance (RθJL) of the BZW06-376BH?
The BZW06-376BH has a typical junction-to-lead thermal resistance of 60°C/W, measured with 9.5 mm lead length at TL = 75°C. This value enables effective heat transfer from the silicon die to PCB copper or heatsinking leads, supporting reliable operation at its 175°C maximum junction temperature-even during repeated surge events in high-ambient environments like engine compartments.
How does the temperature coefficient affect the breakdown voltage of the BZW06-376BH?
The BZW06-376BH has a VBR temperature coefficient of +0.110 %/°C. This means its breakdown voltage increases by approximately 0.110% per degree Celsius rise above 25°C. For example, at 125°C ambient, VBR rises by ~11%, ensuring consistent clamping behavior across automotive thermal ranges without premature conduction or unsafe voltage drift. This coefficient is verified in the BZW06 series datasheet Table on page 2.
