Product details
Overview
BZW04P5V8-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), 10.5 V clamping voltage (VC) at 38 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) capability with 10/1000 μs waveform - ideal for safeguarding sensitive ICs and MOSFETs against inductive switching transients in industrial sensor interfaces.
For engineers reviewing the BZW04P5V8-E3/73 datasheet, BZW04P5V8-E3/73 pinout, BZW04P5V8-E3/73 application, or BZW04P5V8-E3/73 equivalent, key selection criteria include its DO-41 package compatibility, bi-directional clamping symmetry, AEC-Q101 qualification status, low 0.057 %/°C temperature coefficient of breakdown voltage, and 1000 μA maximum reverse leakage at VWM - all critical for automotive-grade ESD and surge resilience in constrained layouts.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, delivering consistent clamping performance without polarity dependency. Its glass-passivated junction ensures stable breakdown behavior and fast response (<1 ns), while the 10/1000 μs waveform rating reflects standardized surge immunity per ANSI/IEEE C62.35.
The device sustains repetitive 400 W pulses at 0.01 % duty cycle and derates linearly above 25 °C ambient, with maximum junction temperature rated at +175 °C. Its 1.5 W steady-state power dissipation (PD) and matte tin-plated leads compliant to J-STD-002 support reliable soldering and long-term thermal stability in high-reliability PCB assemblies.
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 | Unidirectional; 5.0 V VWM; SMA package (surface-mount); 600 W PPPM rating. | Requires polarity-aware placement; better suited for space-constrained SMT designs with higher surge margin. | Select when board real estate is limited and unidirectional protection suffices with tighter VWM tolerance. |
| P6KE6.8A | Unidirectional; 6.8 V VWM; DO-15 package; 600 W PPPM; higher VF and larger footprint. | Larger thermal mass but lower clamping ratio; less precise VBR tolerance than BZW04P5V8-E3/73. | Choose for legacy DO-15 socket compatibility or where higher single-pulse energy absorption is prioritized over precision clamping. |
Compared with SMBJ5.0A and P6KE6.8A, BZW04P5V8-E3/73 offers bi-directional symmetry in a compact DO-41 through-hole package with tighter VBR tolerance (±7.5 %), lower temperature coefficient (0.057 %/°C), and AEC-Q101 qualification - making it uniquely suitable for new automotive and industrial designs requiring polarity-agnostic, high-reliability surge suppression.

FAQ
What is the clamping voltage of BZW04P5V8-E3/73 under maximum surge conditions?
The BZW04P5V8-E3/73 has a maximum clamping voltage (VC) of 10.5 V at 38 A peak pulse current (IPPM), measured with a 10/1000 μs waveform. This value represents the upper voltage limit imposed on protected circuitry during a full-rated 400 W transient event, ensuring downstream 5 V logic remains within safe operating margins. The clamping performance is verified per ANSI/IEEE C62.35 standards and applies equally in both directions due to its bi-directional design.
Is BZW04P5V8-E3/73 suitable for automotive applications?
Yes, BZW04P5V8-E3/73 is AEC-Q101 qualified and explicitly rated for automotive use. Its DO-41 package, +175 °C maximum junction temperature, glass-passivated junction, and low temperature coefficient (0.057 %/°C) meet stringent requirements for engine bay, chassis, and ADAS sensor modules. Vishay's documentation confirms qualification per AEC-Q101 Rev D, including HTOL, TCT, and ESD testing - making BZW04P5V8-E3/73 appropriate for safety-critical vehicle subsystems.
How does the bi-directional nature of BZW04P5V8-E3/73 affect PCB layout?
The bi-directional architecture of BZW04P5V8-E3/73 eliminates polarity marking - there is no cathode band, and either lead functions identically. This simplifies PCB layout by removing orientation constraints during placement and enabling direct replacement of failed units without verifying terminal alignment. It also avoids risk of misplacement-induced open-circuit failure, which is especially valuable in high-mix manufacturing and field repair scenarios involving multiple TVS variants.
What is the maximum reverse leakage current for BZW04P5V8-E3/73 at its stand-off voltage?
At its 5.8 V stand-off voltage (VWM), the BZW04P5V8-E3/73 exhibits a maximum reverse leakage current (ID) of 1000 μA at 25 °C. This specification is confirmed in the Vishay datasheet (Document Number: 88316, Table "ELECTRICAL CHARACTERISTICS") and remains stable across temperature due to the device's low temperature coefficient. The leakage value is sufficiently low to avoid loading high-impedance sensor outputs or compromising battery-powered standby current budgets.
Does BZW04P5V8-E3/73 require heatsinking in typical applications?
No, BZW04P5V8-E3/73 does not require external heatsinking for transient suppression duty cycles. Its 1.5 W steady-state power dissipation (PD) rating assumes operation on an infinite heatsink at TL = 75 °C, but normal use involves only brief, non-repetitive surges (0.01 % duty cycle). In standard PCB layouts with 1 oz copper and minimal trace length, thermal rise remains negligible - validated by Vishay's derating curve (Fig. 2) showing >90 % power retention up to 100 °C ambient.
