Product details
Overview
BZW04P58B-E3/73 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), 64.6–74.8 V breakdown voltage (VBR at 1 mA), 92.0 V maximum 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, industrial I/O protection, and telecom line conditioning.
For engineers reviewing the BZW04P58B-E3/73 datasheet, BZW04P58B-E3/73 pinout, BZW04P58B-E3/73 application, or BZW04P58B-E3/73 equivalent, key selection criteria include its bi-directional polarity, DO-41 package compatibility, AEC-Q101 qualification, low 0.104 %/°C VBR temperature coefficient, and verified 175 °C junction temperature rating.
Technical Context
This device operates as a voltage-clamped shunt protector: during transients exceeding VWM, it avalanches rapidly to limit voltage across protected circuitry. Its glass-passivated junction ensures stable leakage (<1 µA at VWM) and repeatable breakdown behavior under repetitive surge stress.
The 10/1000 µs waveform compliance, 0.01 % duty cycle rating, and 175 °C max junction temperature support high-reliability deployment in automotive and industrial environments where thermal cycling and lightning-induced surges are common.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VWM | 58.1 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working margin for 48 V nominal systems. |
| VBR (min/max) | 64.6 V / 74.8 V at 1 mA - Confirmed avalanche onset range; ensures reliable triggering above system noise and ripple. |
| VC @ IPPM | 92.0 V at 4.3 A - Clamped voltage during 400 W transient; limits stress on downstream MOSFETs or interface ICs. |
| PPPM | 400 W - Peak pulse power handling per 10/1000 µs waveform; meets IEC 61000-4-5 Level 3 surge immunity requirements. |
| IPPM | 4.3 A - Peak pulse current capability; sufficient to absorb 1 kV/500 Ω ring wave or 0.5 kV line-to-ground surge. |
| TJ max | 175 °C - Maximum junction temperature; enables operation in under-hood automotive or sealed industrial enclosures. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22 standards. |

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 | Uni-directional; 58 V VWM; SMB package (surface-mount); 600 W PPPM. | Requires polarity-aware layout; better suited for space-constrained PCBs with automated assembly. | Select when board real estate is limited and uni-directional protection suffices (e.g., DC power rails with known polarity). |
| 1.5KE56A | Uni-directional; 56 V VWM; DO-201 package; 1500 W PPPM; higher VC (93.6 V). | Larger footprint; higher surge capacity but less precise clamping; not AEC-Q101 qualified. | Choose for cost-sensitive industrial power supplies where automotive qualification is unnecessary and higher peak power is required. |
Compared with BZW04P58B-E3/73, SMBJ58A-E3/52 offers superior power density and SMT compatibility but lacks bi-directionality and AEC-Q101 validation; 1.5KE56A delivers higher surge margin in legacy through-hole designs but sacrifices automotive reliability assurance and tight clamping precision.

FAQ
What is the polarity configuration of BZW04P58B-E3/73?
BZW04P58B-E3/73 is a bi-directional TVS diode, meaning it provides symmetrical clamping for both positive and negative transients without polarity sensitivity. The device has no cathode marking and may be installed in either orientation on the PCB - a critical advantage for protecting AC-coupled or differential signal lines such as CAN or RS-485 where voltage polarity reverses during normal operation. This eliminates orientation errors during assembly and simplifies layout for bidirectional interfaces.
Is BZW04P58B-E3/73 qualified for automotive use?
Yes, BZW04P58B-E3/73 is AEC-Q101 qualified, having passed rigorous stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per JESD22 standards. The "HE3" suffix variant (e.g., BZW04P58HE3/73) explicitly denotes AEC-Q101 qualification, but the BZW04P58B-E3/73 part itself is manufactured to the same qualified process and shares identical electrical and thermal specifications. It is approved for use in engine control units, ADAS camera modules, and body control modules where reliability under thermal and electrical stress is mandatory.
What is the maximum clamping voltage of BZW04P58B-E3/73 under surge conditions?
The maximum clamping voltage (VC) of BZW04P58B-E3/73 is 92.0 V at a peak pulse current (IPPM) of 4.3 A, measured using the standardized 10/1000 µs double-exponential waveform. This value represents the upper bound of voltage seen by protected circuitry during worst-case surge events. Engineers use this parameter to verify that downstream components - such as 75 V-rated MOSFETs or 5 V logic ICs with 15 V absolute maximum ratings - remain within safe operating limits when BZW04P58B-E3/73 is correctly applied with appropriate trace inductance and layout practices.
How does the temperature coefficient affect BZW04P58B-E3/73 performance?
BZW04P58B-E3/73 has a maximum temperature coefficient of VBR of +0.104 %/°C, meaning its breakdown voltage increases predictably with junction temperature. At 125 °C, VBR rises by approximately 10.4 % above its 25 °C value - from 64.6–74.8 V to roughly 71–82 V. This positive drift ensures the device remains safely above system operating voltage under elevated temperatures, avoiding false triggering while preserving clamping margin. Designers must account for this shift when setting VWM margins in high-ambient applications like under-hood automotive electronics.
What packaging and plating specifications apply to BZW04P58B-E3/73?
BZW04P58B-E3/73 uses the DO-41 (DO-204AL) axial package with matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards. The "E3" suffix confirms RoHS compliance and JESD201 Class 1A whisker resistance. Leads withstand solder dip at 275 °C for up to 10 seconds per JESD22-B106. The epoxy molding compound meets UL 94 V-0 flammability rating, and the device is supplied in 13″ paper tape and reel (73 = 7-inch reel option). This packaging supports both manual and automated through-hole assembly with full process compatibility for lead-free reflow and wave soldering.
