Product details
Overview
BZW04P8V5BHE3/54 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode designed for robust overvoltage protection in signal and power lines. It features a 8.55 V stand-off voltage (VWM), 14.5 V maximum clamping voltage (VC) at 27.6 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - suitable for safeguarding MOSFETs, ICs, and sensor signal lines against inductive switching transients and ESD in automotive and industrial control systems.
For engineers reviewing the BZW04P8V5BHE3/54 datasheet, BZW04P8V5BHE3/54 pinout, BZW04P8V5BHE3/54 application, or BZW04P8V5BHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AL (DO-41) package, bi-directional symmetry, low 0.07 %/°C temperature coefficient of breakdown voltage, and verified 175 °C junction temperature rating.
Technical Context
This device operates as a voltage-clamped shunt protector: during transient events exceeding its 9.50–11.0 V breakdown range (tested at 1 mA), it rapidly switches to low-impedance conduction, limiting downstream voltage to ≤14.5 V. Its glass-passivated junction ensures stable leakage (<10 µA at VWM) and fast response time (<1 ns), critical for protecting sensitive analog and digital inputs.
The bi-directional architecture enables symmetrical clamping in both polarities without polarity marking, eliminating orientation concerns in AC-coupled or floating signal paths. Thermal performance is defined by 1.5 W steady-state power dissipation on infinite heatsink and full derating above 25 °C ambient per Figure 2, supporting reliable operation in high-temperature environments up to TJ = 175 °C.
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 |
|---|---|---|---|
| SMBJ8.5CA | Same DO-214AA package; higher 600 W PPPM but 15.0 V VC at 38.9 A - less tight clamping margin than BZW04P8V5BHE3/54's 14.5 V. | Preferred where board space allows SMC/SMB footprint and higher surge energy must be absorbed. | Select SMBJ8.5CA only if system-level testing confirms 0.5 V higher clamping does not violate protected IC's absolute maximum ratings. |
| P6KE8.5CA | DO-15 package; same 8.5 V VWM and 14.5 V VC, but lower 600 W rating derated to 400 W at TA > 50 °C - reduced thermal margin in enclosed enclosures. | Used in cost-sensitive consumer products where AEC-Q101 is not required and ambient temperature stays <45 °C. | Choose P6KE8.5CA only for non-automotive applications with verified thermal management and no requirement for automotive qualification. |
