Product details
Overview
BZW04P5V8B-E3/73 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode designed for robust overvoltage protection on signal and power lines. It features a 5.8 V stand-off voltage (VWM), 400 W peak pulse power rating (10/1000 μs), clamping voltage of 10.5 V at 38 A, and operates across –55 °C to +175 °C - ideal for automotive sensor interface and industrial I/O line protection.
For engineers reviewing the BZW04P5V8B-E3/73 datasheet, BZW04P5V8B-E3/73 pinout, BZW04P5V8B-E3/73 application, or BZW04P5V8B-E3/73 equivalent, key selection criteria include its bi-directional clamping behavior, DO-41 package compatibility, AEC-Q101 qualification, low leakage (<1000 µA at 5.8 V), and verified performance under repetitive 10/1000 μs surge waveforms in harsh environments.
Technical Context
This bi-directional TVS diode uses a glass-passivated silicon junction to deliver fast response (<1 ns) and low incremental surge resistance, enabling effective suppression of ESD, lightning-induced transients, and inductive switching spikes. Its symmetrical breakdown (6.45–7.48 V at 10 mA) ensures identical clamping in both polarities without polarity marking.
The device complies with AEC-Q101 for automotive use and meets UL 94 V-0 flammability requirements via its molded epoxy DO-204AL (DO-41) package. Thermal derating follows a defined curve up to 175 °C junction temperature, supporting reliable operation in under-hood and industrial control applications.
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; SMB package (surface-mount); lower IPPM (43.3 A) | Requires polarity-aware layout; better suited for space-constrained PCBs with DC-biased lines. | Select when board area is limited and unidirectional protection suffices (e.g., 5 V supply rail). |
| P6KE6.8A | Uni-directional; 6.8 V VWM; DO-15 package; same 400 W rating but higher VC (10.5 V @ 38.2 A) | Larger footprint; slightly higher clamping voltage reduces margin for 5 V logic. | Choose for legacy through-hole designs where DO-41 and DO-15 footprints are compatible and AEC-Q101 is not required. |
Compared with BZW04P5V8B-E3/73, SMBJ5.0A offers surface-mount convenience but lacks bi-directionality and AEC-Q101 validation, while P6KE6.8A matches power handling but trades automotive qualification and tighter VWM tolerance for broader industry availability.

FAQ
What is the clamping voltage of the BZW04P5V8B-E3/73 under a 10/1000 μs surge?
The BZW04P5V8B-E3/73 clamps to a maximum of 10.5 V when subjected to a 38 A peak pulse current with a 10/1000 μs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during standardized surge events - critical for ensuring compatibility with 5 V logic families and analog sensors.
Is the BZW04P5V8B-E3/73 suitable for automotive applications?
Yes, the BZW04P5V8B-E3/73 is AEC-Q101 qualified and rated for operation from –55 °C to +175 °C, making it suitable for under-hood and chassis-mounted automotive electronics. Its glass-passivated junction and DO-41 package meet stringent vibration, thermal cycling, and humidity requirements specified in the AEC standard.
How does the bi-directional nature of the BZW04P5V8B-E3/73 affect its PCB layout?
The BZW04P5V8B-E3/73 has no polarity marking and functions identically in either orientation, simplifying PCB layout and eliminating orientation errors during assembly. This symmetry allows direct placement across differential lines or AC-coupled signals without concern for anode/cathode alignment - reducing design review cycles and manufacturing defects.
What is the maximum reverse leakage current for the BZW04P5V8B-E3/73 at its stand-off voltage?
At its 5.8 V stand-off voltage (VWM) and TA = 25 °C, the BZW04P5V8B-E3/73 exhibits a maximum reverse leakage current of 1000 µA. This low leakage ensures minimal impact on high-impedance sensor circuits and prevents excessive power dissipation in battery-powered or energy-sensitive applications.
Does the BZW04P5V8B-E3/73 require heatsinking for 400 W pulse handling?
No - the 400 W peak pulse power rating applies to non-repetitive 10/1000 μs transients and does not require external heatsinking. The device relies on thermal mass and short-duration energy absorption; however, for repetitive surges or elevated ambient temperatures, derating per Figure 2 in the datasheet must be applied to maintain safe junction temperature limits.
