Product details
Overview
BZW04-58HE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of signal and power lines. It features a 58.1 V stand-off voltage (VWM), 64.6–71.4 V breakdown range (VBR at 1 mA), 92.0 V clamping voltage (VC) at 4.3 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.
For engineers reviewing the BZW04-58HE3/54 datasheet, BZW04-58HE3/54 pinout, BZW04-58HE3/54 application, or BZW04-58HE3/54 equivalent, this AEC-Q101 qualified TVS offers verified bidirectional clamping, low leakage (<1.0 μA at VWM), and stable temperature coefficient (0.104 %/°C), supporting design validation for ESD and load-dump immunity in harsh environments.
Technical Context
This device operates as a voltage-clamped shunt protector: when transient voltage exceeds VBR, it avalanches into low-impedance conduction to divert surge energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive surges.
Designed for bidirectional operation, BZW04-58HE3/54 provides symmetrical clamping in both polarities without polarity marking, enabling use on AC-coupled or floating signal paths. It meets JESD22-B102 solderability and JESD201 class 2 whisker resistance requirements, with UL 94 V-0 molded epoxy encapsulation.
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 |
|---|---|---|---|
| SMBJ58A-E3/52 (Vishay) | Surface-mount SMB package; unidirectional; same VWM/VC specs but 600 W PPPM. | Requires PCB layout change; suited for high-density SMT designs where DO-41 axial leads are impractical. | Select when board space is constrained and reflow assembly is preferred; verify unidirectional polarity alignment in schematic. |
| P6KE56CA (Littelfuse) | DO-15 package; 56 V VWM; 400 W rating; slightly lower VBR (62.2–68.7 V) and higher VC (93.6 V). | Compatible mechanical footprint but not AEC-Q101 qualified; intended for commercial/industrial use only. | Choose for cost-sensitive non-automotive applications where AEC-Q101 is not mandated and 2 V lower VWM is acceptable. |
Compared with BZW04-58HE3/54, SMBJ58A-E3/52 offers higher surge power in compact SMT form but requires redesign, while P6KE56CA provides drop-in mechanical compatibility at lower qualification grade and marginal VWM reduction - making BZW04-58HE3/54 the optimal choice for AEC-Q101-compliant, through-hole, bidirectional protection.

FAQ
What is the polarity configuration of BZW04-58HE3/54?
BZW04-58HE3/54 is a bidirectional TVS diode with no polarity marking on the DO-41 package. Its symmetrical structure allows installation in either orientation, making it ideal for AC-coupled signals, differential buses, or floating ground systems where polarity cannot be guaranteed. This eliminates risk of incorrect placement during manual or automated assembly.
Does BZW04-58HE3/54 meet automotive qualification standards?
Yes, BZW04-58HE3/54 carries the HE3 suffix, confirming full AEC-Q101 qualification per Vishay documentation (Document Number 88316, Revision 16-Sep-2021). It has passed stress tests including high-temperature operating life, temperature cycling, and humidity bias HAST - validating its suitability for under-hood and chassis-mounted automotive electronics.
What is the maximum clamping voltage of BZW04-58HE3/54 under surge conditions?
The maximum clamping voltage (VC) of BZW04-58HE3/54 is 92.0 V at 4.3 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is guaranteed across production lots and represents the upper limit of voltage seen by protected circuitry during standardized surge events per IEC 61000-4-5.
How does the HE3 suffix differ from the E3 suffix in BZW04-58HE3/54?
The HE3 suffix in BZW04-58HE3/54 denotes AEC-Q101 qualification and JESD201 class 2 whisker resistance, whereas E3 indicates RoHS-compliant commercial grade only. Both share DO-41 packaging and identical electrical specs, but HE3 adds automotive-grade reliability validation - critical for safety-critical or mission-critical deployments.
Can BZW04-58HE3/54 be used in place of unidirectional TVS diodes?
BZW04-58HE3/54 is strictly bidirectional and should not replace unidirectional TVS diodes in DC-biased circuits requiring cathode-anode polarity alignment. However, it can substitute other bidirectional parts like BZW04-58B or P6KE56CA in AC or floating applications - always verify VWM, VC, and surge rating alignment before substitution.
