Product details
Overview
BZW04P58-E3/73 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 58.1 V stand-off voltage (VWM), 92.0 V maximum clamping voltage (VC) at 4.3 A peak pulse current (IPPM), and 400 W peak pulse power dissipation with a 10/1000 µs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and DC power rail protection.
For engineers reviewing the BZW04P58-E3/73 datasheet, BZW04P58-E3/73 pinout, BZW04P58-E3/73 application, or BZW04P58-E3/73 equivalent, key selection criteria include its DO-41 package compatibility, AEC-Q101 qualification, bi-directional surge handling up to ±4.3 A, and low 0.104 %/°C temperature coefficient of breakdown voltage - critical for stable clamping across automotive temperature ranges.
Technical Context
This bi-directional TVS diode uses a glass-passivated silicon junction to achieve fast response (<1 ns) and low incremental surge resistance, enabling effective suppression of ESD, lightning-induced transients, and inductive switching spikes. Its symmetrical breakdown behavior (VBR = 64.6–74.8 V at 1 mA) ensures identical clamping performance in both polarities without polarity marking.
The device operates across –55 °C to +175 °C junction temperature and is rated for 1.5 W steady-state power dissipation on an infinite heatsink at 75 °C. It meets JESD22-B106 solderability (275 °C, 10 s) and JESD201 Class 1A whisker testing (E3 suffix), confirming suitability for automated assembly in high-reliability applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58.1 V - Maximum continuous reverse operating voltage before conduction; defines safe working margin below clamping threshold. |
| VC @ IPPM | 92.0 V at 4.3 A - Clamped voltage during 10/1000 µs surge; limits downstream IC stress to sub-92 V under worst-case 400 W transient. |
| PPPM | 400 W - Peak pulse power rating with 10/1000 µs waveform; supports repetitive surge events at 0.01 % duty cycle. |
| VBR min/max | 64.6 V / 74.8 V at 1 mA - Validated breakdown range ensures consistent turn-on behavior across production lots and temperature. |
| TJ max | +175 °C - Maximum junction temperature; enables operation in under-hood automotive and industrial environments without derating. |
| Temp. Coeff. | 0.104 %/°C - Low VBR drift with temperature; maintains predictable clamping across –40 °C to +125 °C ambient. |
| Package | DO-204AL (DO-41) - Standard axial-leaded through-hole package with 0.205" body diameter; compatible with legacy PCB layouts and wave soldering. |
Pinout & Package
DO-204AL (DO-41) package: axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards. Bi-directional construction means no cathode marking - terminals are electrically symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Bi-directional terminals conduct identically in either polarity; no polarity-dependent mounting required. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock - suitable for engine control and ADAS sensor protection. |
| Glass passivated junction | Enables stable leakage performance (<1 µA at VWM) and long-term stability under thermal stress and humidity exposure. |
| 400 W 10/1000 µs pulse rating | Withstands repeated high-energy transients common in 12 V/24 V vehicle power systems and industrial motor drives without degradation. |
| RoHS-compliant E3 suffix | Meets JESD201 Class 1A whisker test and Directive 2011/65/EU - certified for lead-free reflow and wave soldering processes. |
| Low clamping ratio (VC/VWM = 1.58) | Minimizes protected circuit overvoltage margin - reduces need for oversized downstream voltage ratings and improves system-level EMI resilience. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

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; SMC package (surface-mount) | Requires polarity-aware layout; unsuitable for AC-coupled or floating signal lines without external biasing. | Select when board space is constrained and uni-directional protection suffices (e.g., DC supply rails with known polarity). |
| P6KE56CA | Bi-directional; 56 V VWM, 93.6 V VC @ 4.3 A; DO-15 package (larger than DO-41, 0.260" diameter) | Higher VWM tolerance (±5 % vs. BZW04P58's ±8.7 %); lower surge life due to larger junction thermal mass. | Choose for legacy DO-15 footprint compatibility or where higher surge endurance per pulse is prioritized over compactness. |
Compared with SMBJ58A and P6KE56CA, BZW04P58-E3/73 offers tighter VWM tolerance (±3.4 %), smaller DO-41 footprint, and AEC-Q101 qualification - making it optimal for new automotive and space-constrained industrial designs requiring bi-directional clamping without polarity constraints.

FAQ
What is the clamping voltage of BZW04P58-E3/73 under a standard 10/1000 µs surge?
The BZW04P58-E3/73 clamps to a maximum of 92.0 V when subjected to its rated 4.3 A peak pulse current (IPPM) using the industry-standard 10/1000 µs double-exponential waveform. This value is guaranteed across production lots and validated per ANSI/IEEE C62.35, ensuring predictable overvoltage limiting for downstream ICs in BZW04P58-E3/73-protected circuits.
Is BZW04P58-E3/73 suitable for automotive applications?
Yes, BZW04P58-E3/73 is AEC-Q101 qualified and manufactured with glass-passivated junction technology to withstand automotive stress conditions including temperature cycling, humidity bias, and mechanical vibration. Its DO-41 package and –55 °C to +175 °C operating range make BZW04P58-E3/73 appropriate for under-hood and cabin ECU protection, particularly in sensor signal paths and 12 V/24 V power domains.
How does the bi-directional nature of BZW04P58-E3/73 affect its PCB layout?
Because BZW04P58-E3/73 is bi-directional, it has no polarity marking and conducts identically in both directions - eliminating the need for orientation-specific placement. This simplifies layout for AC-coupled lines, floating sensors, or differential buses like RS-485, where polarity ambiguity would otherwise require dual uni-directional devices or careful trace routing. The DO-41 package allows direct replacement of legacy bi-directional suppressors without redesign.
What is the maximum steady-state power dissipation for BZW04P58-E3/73?
BZW04P58-E3/73 has a maximum steady-state power dissipation (PD) of 1.5 W when mounted on an infinite heatsink at a lead temperature (TL) of 75 °C. In practical through-hole applications with standard 0.375" (9.5 mm) lead length, derating per Figure 5 in the datasheet applies - e.g., ~1.0 W at TL = 100 °C. This rating governs continuous leakage-based heating, not transient surge handling.
Does BZW04P58-E3/73 meet RoHS and lead-free assembly requirements?
Yes, the "E3" suffix in BZW04P58-E3/73 indicates full compliance with RoHS Directive 2011/65/EU and JESD201 Class 1A whisker testing. Its matte tin-plated leads are qualified for lead-free wave and reflow soldering per J-STD-002 and JESD22-B102, supporting modern high-volume manufacturing without post-solder cleaning or special flux requirements for BZW04P58-E3/73 integration.
