Product details
Overview
BZW04P58B-E3/54 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 58.1 V stand-off voltage (VWM), 92.0 V clamping voltage (VC) at 4.3 A peak pulse current (IPPM), and 400 W peak pulse power (10/1000 µs waveform), making it suitable for protecting MOSFETs, sensor interfaces, and industrial control inputs against ESD and inductive switching transients.
For engineers reviewing the BZW04P58B-E3/54 datasheet, BZW04P58B-E3/54 pinout, BZW04P58B-E3/54 application, or BZW04P58B-E3/54 equivalent, key selection considerations include its DO-204AL (DO-41) axial package, bi-directional symmetry, AEC-Q101 qualification, low leakage (<1 µA at VWM), and temperature coefficient of breakdown voltage (0.104 %/°C).
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with identical electrical characteristics forward and reverse - critical for AC-coupled or floating signal line protection. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance, enabling fast response (<1 ns) to transients while maintaining tight clamping performance across temperature.
The device is rated for 400 W peak pulse power under standard 10/1000 µs waveform conditions, derated linearly above 25 °C ambient per Figure 2, and supports continuous power dissipation of 1.5 W on an infinite heatsink at lead temperature (TL) = 75 °C. Junction temperature range spans –55 °C to +175 °C, supporting harsh automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 58.1 V - Maximum continuous working voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VC @ IPPM | 92.0 V at 4.3 A - Clamped voltage during 10/1000 µs surge; determines maximum stress imposed on protected downstream circuitry. |
| IPPM (Peak Pulse Current) | 4.3 A - Peak transient current the device safely shunts without degradation; derived from 400 W rating and VC. |
| VBR (Breakdown Voltage) | 64.6–74.8 V at 1 mA - Voltage at which device enters avalanche; tolerance band informs design margin for worst-case clamping. |
| TJmax | +175 °C - Maximum junction temperature; enables operation in under-hood automotive or high-ambient industrial settings. |
| Leakage Current (ID) | <1 µA at VWM - Minimal standby power loss and signal integrity impact in high-impedance circuits. |
| Temp. Coeff. of VBR | 0.104 %/°C - Predictable drift of breakdown voltage with temperature; essential for thermal stability in wide-range applications. |
Pinout & Package
Package: DO-204AL (DO-41), axial-leaded, epoxy-molded case meeting UL 94 V-0 flammability rating. Matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards. Bi-directional types have no polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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 | Uni-directional; 58 V VWM, 93.6 V VC @ 4.3 A; SMB package (surface-mount) | Requires polarity-aware layout; better suited for PCB space-constrained designs with unidirectional DC rails. | Select when board real estate is limited and circuit polarity is fixed; verify grounding scheme accommodates uni-directional behavior. |
| P6KE56CA | Bi-directional; 56 V VWM, 93.6 V VC @ 4.3 A; DO-15 package (larger than DO-41) | Higher leakage (~5 µA); lower power density (600 W vs. 400 W rating but larger footprint) | Choose if legacy DO-15 footprint compatibility is required or higher surge margin is needed despite larger size. |
Compared with BZW04P58B-E3/54, SMBJ58A offers surface-mount convenience but lacks bi-directional symmetry, while P6KE56CA provides similar clamping but in a less compact axial package with higher leakage - BZW04P58B-E3/54 balances AEC-Q101 qualification, DO-41 fit, and low-leakage bi-directional protection.

FAQ
What is the clamping voltage of the BZW04P58B-E3/54 under standard surge conditions?
The BZW04P58B-E3/54 exhibits a maximum clamping voltage (VC) of 92.0 V when subjected to a 10/1000 µs peak pulse current of 4.3 A. This value is measured per IEC 61000-4-5 and ANSI/IEEE C62.35 standards and represents the upper voltage limit imposed on protected circuitry during transient events - a key parameter for ensuring downstream ICs remain within absolute maximum ratings.
Is the BZW04P58B-E3/54 suitable for automotive applications?
Yes, the BZW04P58B-E3/54 is AEC-Q101 qualified and specified for operation from –55 °C to +175 °C junction temperature. Its glass-passivated junction, low leakage, and stable clamping performance make it appropriate for under-hood and chassis-mounted automotive subsystems, including engine control units, body control modules, and ADAS sensor interfaces where ISO 7637-2 pulse immunity is required.
How does the bi-directional nature of the BZW04P58B-E3/54 affect its placement in circuit design?
The BZW04P58B-E3/54 has no polarity marking and functions identically in both directions, allowing placement across AC-coupled lines, differential pairs (e.g., RS-485), or floating supplies without orientation concerns. This eliminates risk of incorrect installation and simplifies layout for bidirectional signal paths - unlike uni-directional TVS diodes such as SMBJ58A, which require strict cathode/anode alignment relative to system ground.
What is the maximum continuous power dissipation for the BZW04P58B-E3/54?
The BZW04P58B-E3/54 has a maximum steady-state power dissipation (PD) of 1.5 W when mounted on an infinite heatsink at lead temperature (TL) = 75 °C. In practical PCB layouts, derating is required based on thermal resistance; typical free-air PD is ~0.8 W. This rating governs safe operation under sustained overvoltage or high-duty-cycle transient conditions.
Does the BZW04P58B-E3/54 meet RoHS and REACH requirements?
Yes, the BZW04P58B-E3/54 carries the "E3" suffix indicating full compliance with RoHS Directive 2011/65/EU (recast) and alignment with WEEE 2002/96/EC. It contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits, and Vishay certifies material content per its Material Category Policy - confirmed in Document Number 88316 and 91000.
