Product details
Overview
BZW04P5V8BHE3/54 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 5.8 V stand-off voltage (VWM), 10.5 V clamping voltage (VC) at 38 A peak pulse current, and 400 W peak pulse power capability with a 10/1000 μs waveform. It is AEC-Q101 qualified and used to protect MOSFETs, ICs, and sensor signal lines against inductive switching transients and ESD in automotive and industrial electronics.
For engineers reviewing the BZW04P5V8BHE3/54 datasheet, BZW04P5V8BHE3/54 pinout, BZW04P5V8BHE3/54 application, or BZW04P5V8BHE3/54 equivalent, key selection criteria include its bi-directional polarity, DO-41 package compatibility, low clamping ratio (VC/VWM ≈ 1.81), -55 °C to +175 °C operating junction temperature range, and RoHS-compliant AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a voltage-clamped surge protector using an avalanche breakdown mechanism in both directions, enabling symmetric transient suppression without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, critical for consistent clamping under repetitive 10/1000 μs pulses at 0.01% duty cycle.
The BZW04P5V8BHE3/54 exhibits a 0.057 %/°C temperature coefficient of breakdown voltage and maintains <1000 nA reverse leakage at 5.8 V (VWM), supporting low-power system integrity. It is rated for 1.5 W steady-state power dissipation on an infinite heatsink at 75 °C lead temperature and withstands solder dip up to 275 °C for 10 s per JESD22-B106.
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 |
|---|---|---|---|
| SMBJ5.0A | Uni-directional; 5.0 V VWM; 9.2 V VC @ 43.5 A; DO-214AA package | Requires polarity-aware layout; higher clamping ratio (1.84); lower mounting density than axial DO-41 | Select when unidirectional protection suffices and surface-mount assembly is preferred. |
| P6KE6.8CA | 600 W PPPM; 6.8 V VWM; 10.5 V VC @ 57.1 A; DO-15 package | Higher surge rating but larger DO-15 body (0.260" diameter); not AEC-Q101 qualified | Choose for cost-sensitive industrial applications where automotive qualification is unnecessary and higher pulse energy is required. |

The BZW04P5V8BHE3/54 has a maximum clamping voltage (VC) of 10.5 V at 38 A peak pulse current with a 10/1000 μs waveform. This value is measured per IEC 61000-4-5 test conditions and represents the upper voltage limit imposed on protected circuitry during a standardized surge event. The BZW04P5V8BHE3/54 maintains this clamping performance across its full operating temperature range of -55 °C to +175 °C.
Is the BZW04P5V8BHE3/54 suitable for automotive applications?
Yes, the BZW04P5V8BHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use.

The BZW04P5V8BHE3/54 is deployed in engine control units, body control modules, and ADAS sensor interfaces where compliance with automotive reliability standards is mandatory.
How does the bi-directional functionality of the BZW04P5V8BHE3/54 affect PCB layout?
The BZW04P5V8BHE3/54 has no polarity marking and functions identically in both directions, eliminating orientation constraints during placement. This simplifies PCB layout by removing the need for silkscreen polarity indicators or automated optical inspection (AOI) checks for cathode alignment. The BZW04P5V8BHE3/54 can be mounted in either direction across a differential line or power rail, reducing assembly errors and enabling reuse in symmetrical protection schemes such as RS-485 or CAN bus termination networks.
What is the reverse leakage current specification for the BZW04P5V8BHE3/54 at its stand-off voltage?
The BZW04P5V8BHE3/54 specifies a maximum reverse leakage current (ID) of 1000 nA at its 5.8 V stand-off voltage (VWM) and 25 °C ambient temperature. This low leakage ensures minimal impact on battery life in portable systems and avoids loading errors in high-impedance sensor bias networks. The BZW04P5V8BHE3/54 maintains leakage below 5 µA up to 85 °C, supporting reliable operation in thermally demanding enclosures.
Does the BZW04P5V8BHE3/54 meet RoHS and REACH compliance requirements?
