Product details
Overview
BZW04P5V8B-E3/54 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), 10.5 V clamping voltage (VC) at 38 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection circuits.
For engineers reviewing the BZW04P5V8B-E3/54 datasheet, BZW04P5V8B-E3/54 pinout, BZW04P5V8B-E3/54 application, or BZW04P5V8B-E3/54 equivalent, key selection criteria include its bi-directional polarity, DO-41 package compatibility, AEC-Q101 qualification, low 0.057 %/°C VBR temperature coefficient, and compliance with IEC 61000-4-2/4-4/4-5 surge immunity standards.
Technical Context
This device operates as a voltage-clamped shunt protector: during transients exceeding 5.8 V, it avalanches to divert surge current away from downstream circuitry while maintaining <10.5 V across protected nodes. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance under repetitive 10/1000 μs pulses at 0.01 % duty cycle.
Designed for bi-directional operation, BZW04P5V8B-E3/54 has no polarity marking and delivers symmetrical clamping in both directions. It supports continuous operation up to +175 °C junction temperature and meets JESD22-B106 solderability requirements (275 °C, 10 s).
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 @ 43.3 A; SMB package (surface-mount) | Requires polarity-aware layout; better suited for space-constrained PCBs with automated assembly | Select when board area is limited and uni-directional protection suffices with existing ground-referenced architecture |
| P6KE6.8A | Uni-directional; 6.8 V VWM; 10.5 V VC @ 38.2 A; DO-15 package (larger than DO-41) | Higher VWM reduces false triggering but increases let-through voltage margin; legacy through-hole footprint | Choose for cost-sensitive industrial controls where DO-15 compatibility and higher surge margin outweigh size penalties |
Compared with BZW04P5V8B-E3/54, SMBJ5.0A offers surface-mount convenience but lacks bi-directionality and AEC-Q101 validation, while P6KE6.8A provides mechanical robustness and legacy support but requires larger board real estate and does not meet automotive qualification requirements.

FAQ
What is the clamping voltage of BZW04P5V8B-E3/54 and how is it measured?
The clamping voltage of BZW04P5V8B-E3/54 is 10.5 V, measured at 38 A peak pulse current using the standardized 10/1000 μs double-exponential surge waveform. This value represents the maximum voltage that appears across the device terminals during a transient event, directly limiting stress on downstream components such as microcontrollers or transceivers in the BZW04P5V8B-E3/54-protected circuit.
Is BZW04P5V8B-E3/54 suitable for automotive applications?
Yes, BZW04P5V8B-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction - including glass-passivated junction, DO-41 package with UL 94 V-0 molding, and operation up to +175 °C junction temperature - meets stringent requirements for engine control units, body electronics, and ADAS sensor interfaces. The BZW04P5V8B-E3/54 data sheet confirms qualification per AEC-Q101 Rev D test conditions.
How does the bi-directional nature of BZW04P5V8B-E3/54 affect its PCB layout?
The bi-directional design of BZW04P5V8B-E3/54 eliminates polarity marking and allows placement in either orientation across differential or floating lines - simplifying layout, reducing assembly errors, and enabling use on AC-coupled or bidirectional buses like RS-485 or CAN FD. Unlike uni-directional TVS diodes, the BZW04P5V8B-E3/54 requires no anode/cathode alignment check during placement or inspection.
What is the maximum steady-state power dissipation of BZW04P5V8B-E3/54?
The maximum steady-state power dissipation (PD) of BZW04P5V8B-E3/54 is 1.5 W when mounted on an infinite heatsink at lead temperature TL = 75 °C. This rating applies to continuous DC or low-frequency operation - distinct from its 400 W peak pulse rating - and must be derated linearly above 25 °C ambient per the published power derating curve in the BZW04P5V8B-E3/54 datasheet.
Does BZW04P5V8B-E3/54 meet RoHS and REACH compliance requirements?
Yes, BZW04P5V8B-E3/54 carries the "E3" suffix indicating full compliance with RoHS Directive 2011/65/EU and alignment with WEEE 2002/96/EC. Its matte tin-plated leads meet JESD201 Class 1A whisker testing, and the epoxy molding compound is halogen-free per Vishay's material declarations. Compliance documentation for BZW04P5V8B-E3/54 is available via Vishay's official product portal.
