Product details
Overview
BZW04-10BHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of signal and power lines. It features a 10.2 V stand-off voltage (VWM), 11.4–12.6 V breakdown voltage (VBR) at 1 mA test current, 16.7 V clamping voltage (VC) at 24.0 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) capability with 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the BZW04-10BHE3/54 datasheet, BZW04-10BHE3/54 pinout, BZW04-10BHE3/54 application, or BZW04-10BHE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-41 mechanical dimensions, clamping performance under surge conditions, and direct alternatives for circuit-level ESD/transient hardening.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with no polarity marking on the device body. Its glass-passivated junction ensures stable VBR and low leakage (<1.0 μA at VWM), while its 175 °C maximum junction temperature supports operation in under-hood automotive environments.
The device complies with ANSI/IEEE C62.35 surge standards and delivers consistent clamping response across repetitive 10/1000 μs transients at ≤0.01% duty cycle. Its 0.078 %/°C VBR temperature coefficient enables predictable voltage threshold drift over temperature in precision protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10.2 V - maximum continuous reverse working voltage before conduction begins; defines safe operating margin for protected line. |
| VBR min/max | 11.4 V / 12.6 V at 1 mA - guaranteed breakdown onset range; ensures reliable triggering within specified tolerance band. |
| VC @ IPPM | 16.7 V at 24.0 A - clamped voltage during 10/1000 μs surge; determines maximum stress imposed on downstream ICs. |
| PPPM | 400 W - peak transient energy handling capacity; supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when properly laid out. |
| ID @ VWM | <1.0 μA - ultra-low reverse leakage at rated stand-off; minimizes standby power loss and avoids false triggering. |
| TJ max | +175 °C - extended thermal rating enabling use in high-ambient automotive and industrial control applications. |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including HTOL, temperature cycling, and ESD testing per AEC standard. |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with matte tin-plated leads; compliant with UL 94 V-0 flammability rating and J-STD-002 solderability requirements. Bidirectional configuration means both terminals are electrically symmetrical - no anode/cathode distinction; device has no polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both ends serve identical bidirectional clamping function; interchangeable in PCB layout with no orientation constraint. |
| Case (body) | Thermal and mechanical interface | DO-41 cylindrical body provides mechanical anchoring and limited heat dissipation; no electrical connection to case. |

Applications
| Automotive Sensor Interface | Industrial PLC Analog Input |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog front-ends from load dump and ESD events in vehicle cabin modules. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point to shunt transients before reaching MCU or PHY.

Use Value: Handles repetitive 400 W pulses at 0.01% duty cycle without parameter shift, extending motor driver lifetime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | Same DO-214AA package; 10 V VWM, 17.0 V VC @ 23.5 A; 600 W PPPM; higher clamping voltage and larger footprint. | Preferred where board space allows SMB package and higher surge margin is needed beyond 400 W. | Select SMBJ10CA only if layout accommodates wider SMC/SMB footprint and system requires >400 W surge headroom. |
| P6KE10CA | DO-15 package; 10 V VWM, 17.0 V VC @ 23.3 A; 600 W PPPM; lower thermal mass and higher leakage (5.0 μA). | Suitable for cost-sensitive consumer designs where AEC-Q101 is not required and 175 °C TJ rating is unnecessary. | Choose P6KE10CA for non-automotive applications needing lower unit cost and where JEDEC DO-15 mounting is standardized. |
Compared with BZW04-10BHE3/54, SMBJ10CA offers higher surge rating but requires larger PCB area and lacks AEC-Q101 validation; P6KE10CA reduces cost and qualifies for legacy industrial use but sacrifices automotive reliability and thermal robustness.

FAQ
What is the clamping voltage of BZW04-10BHE3/54 under a standard 10/1000 μs surge?
The BZW04-10BHE3/54 exhibits a maximum clamping voltage (VC) of 16.7 V when subjected to its rated peak pulse current of 24.0 A using the 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and represents the upper limit of voltage seen by downstream circuitry during transient events - critical for ensuring compatibility with 3.3 V or 5 V logic interfaces.
Is BZW04-10BHE3/54 suitable for automotive applications?
Yes, BZW04-10BHE3/54 is AEC-Q101 qualified and carries the HE3 suffix indicating compliance with automotive reliability standards including high-temperature operating life, temperature cycling, and ESD testing. Its 175 °C maximum junction temperature and low leakage make it appropriate for engine bay, chassis, and ADAS sensor protection circuits.
How does the bidirectional design of BZW04-10BHE3/54 affect PCB layout?
The bidirectional nature of BZW04-10BHE3/54 eliminates polarity constraints - both terminals are functionally identical, and no cathode band or marking exists on the DO-41 body. This allows unrestricted orientation during placement, simplifying automated assembly and reducing risk of misorientation-related failures in high-volume manufacturing.
What is the meaning of the "HE3/54" suffix in BZW04-10BHE3/54?
The "HE3" denotes RoHS-compliant, AEC-Q101 qualified construction with JESD201 Class 2 whisker-resistant matte tin plating; "/54" specifies the preferred packaging code - 13-inch paper tape and reel containing 550 units. This full suffix confirms both automotive-grade reliability and standardized logistics formatting for SMT placement equipment.
Does BZW04-10BHE3/54 require a heatsink for normal operation?
No, BZW04-10BHE3/54 does not require a heatsink during transient suppression events due to its short-duration pulse handling (10/1000 μs) and low average power dissipation. Its 1.5 W steady-state power rating (PD) applies only to continuous DC conditions - typical surge duty cycles (<0.01%) ensure junction temperature remains within safe limits without additional thermal management.
