Product details
Overview
BZW04-58B-E3/54 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 BZW04-58B-E3/54 datasheet, BZW04-58B-E3/54 pinout, BZW04-58B-E3/54 application, or BZW04-58B-E3/54 equivalent, this device serves as a RoHS-compliant, AEC-Q101-qualified bidirectional TVS for high-reliability transient suppression where low clamping ratio, fast response (<1 ns), and stable temperature coefficient (0.104 %/°C) are critical selection criteria.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical VBR, VC, and leakage characteristics in forward and reverse directions. Its glass-passivated junction ensures stable avalanche behavior and low incremental surge resistance under repetitive 10/1000 μs transients at 0.01% duty cycle.
The device is rated for -55 °C to +175 °C operating junction temperature, supports 1.5 W steady-state power dissipation at TL = 75 °C, and exhibits 1.0 μA maximum reverse leakage at VWM - enabling reliable operation in thermally constrained automotive and industrial environments without derating penalties below 125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58.1 V - maximum continuous working voltage before conduction; defines safe operating margin for 48 V nominal systems. |
| VBR (min/max) | 64.6 V / 71.4 V at 1 mA - tight breakdown tolerance ensures predictable turn-on across production lots and temperature. |
| VC @ IPPM | 92.0 V at 4.3 A - low clamping voltage limits stress on downstream ICs during 400 W transient events. |
| PPPM | 400 W - peak pulse power handling per 10/1000 μs waveform, supporting IEC 61000-4-5 Level 4 surge immunity. |
| ID @ VWM | 1.0 μA - ultra-low leakage preserves signal integrity and battery life in always-on sensor circuits. |
| TJ max | +175 °C - extended junction temperature rating enables placement near heat sources in engine control units. |
| Temp. Coeff. | 0.104 %/°C - stable VBR drift minimizes design margin uncertainty over automotive temperature range. |
Pinout & Package
DO-41 (DO-204AL) axial-leaded package with matte tin-plated leads; no polarity marking - consistent with bidirectional function. Molding compound meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Identical electrical behavior in either direction; no cathode band - simplifies PCB layout and orientation inspection. |

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 | Unidirectional; 58 V VWM; SMA package; 600 W PPPM; higher IPPM (6.8 A). | Requires polarity-aware layout; better suited for DC-biased rails where reverse conduction must be blocked. | Select when unidirectional blocking is required and surface-mount assembly is preferred over axial leads. |
| P6KE62CA | DO-15 package; 62 V VWM; 600 W PPPM; wider VBR tolerance (±10%); no AEC-Q101 qualification. | Larger footprint; lower temperature rating (150 °C); intended for commercial-grade industrial use only. | Choose for cost-sensitive non-automotive applications where 62 V clamping margin is acceptable and AEC-Q101 is not mandated. |
Compared with SMBJ58A-E3/52 and P6KE62CA, the BZW04-58B-E3/54 offers bidirectional symmetry, AEC-Q101 qualification, and tighter VBR tolerance in a compact DO-41 axial package - making it optimal for automotive sensor nodes and space-constrained industrial designs requiring polarity-agnostic protection.

FAQ
What is the clamping voltage of the BZW04-58B-E3/54 under maximum surge conditions?
The BZW04-58B-E3/54 has a maximum clamping voltage (VC) of 92.0 V at 4.3 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per standard test conditions in the Vishay datasheet (Document Number: 88316) and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The BZW04-58B-E3/54 maintains this clamping performance across its full operating temperature range.
Is the BZW04-58B-E3/54 suitable for automotive applications?
Yes, the BZW04-58B-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and sensor interfaces. Its -55 °C to +175 °C operating junction temperature range, glass-passivated junction, and DO-41 mechanical robustness meet automotive reliability requirements. The BZW04-58B-E3/54 carries the HE3 suffix variant for full AEC-Q101 compliance, though the E3/54 version remains widely used in automotive-adjacent industrial designs.
How does the bidirectional nature of the BZW04-58B-E3/54 affect PCB layout?
The BZW04-58B-E3/54 has no polarity marking and identical electrical characteristics in both directions, eliminating orientation constraints during placement. This simplifies automated assembly and reduces risk of misorientation-related failures. Unlike unidirectional TVS diodes, the BZW04-58B-E3/54 can protect AC-coupled or floating signal lines without requiring careful anode/cathode alignment - a key advantage in differential bus protection such as CAN or RS-485 interfaces.
What is the maximum reverse leakage current for the BZW04-58B-E3/54 at its stand-off voltage?
The BZW04-58B-E3/54 specifies a maximum reverse leakage current (ID) of 1.0 μA at its 58.1 V stand-off voltage (VWM) and 25 °C ambient temperature. This ultra-low leakage ensures minimal power loss in battery-powered systems and avoids signal distortion in high-impedance sensor circuits. The BZW04-58B-E3/54 maintains leakage below 5 μA even at 125 °C, supporting reliable operation in thermally demanding environments.
Does the BZW04-58B-E3/54 require heatsinking for continuous power dissipation?
No, the BZW04-58B-E3/54 is not intended for continuous power dissipation; its 1.5 W rating (PD) applies only to power dissipation on an infinite heatsink at lead temperature (TL) = 75 °C - a derated condition for short-duration thermal evaluation. In normal operation, the BZW04-58B-E3/54 handles only transient energy (400 W peak, 0.01% duty cycle), so no heatsink is required. Its DO-41 package relies on PCB copper area for transient thermal mass, not steady-state cooling.
