Product details
Overview
BZW04-58BHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features a 58.1 V stand-off voltage (VWM), 64.6–71.4 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 - suitable for protecting automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the BZW04-58BHE3/54 datasheet, BZW04-58BHE3/54 pinout, BZW04-58BHE3/54 application, or BZW04-58BHE3/54 equivalent, this device delivers AEC-Q101-qualified transient suppression for bidirectional AC-coupled lines, high-temperature operation up to +175 °C, low leakage (<1.0 μA at VWM), and robust surge immunity per IEC 61000-4-5.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical VBR, VC, and IPPM specifications for positive and negative transients. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance.
The device is rated for 400 W peak pulse power (10/1000 μs), 1.5 W steady-state power dissipation, and supports operating junction temperatures from –55 °C to +175 °C. It meets JESD22-B106 solderability standards and JESD201 class 2 whisker resistance (HE3 suffix).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58.1 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin for 48 V nominal systems. |
| VBR (min/max) | 64.6 V / 71.4 V at 1 mA - Verified breakdown threshold range ensures reliable turn-on during overvoltage events without premature conduction. |
| VC @ IPPM | 92.0 V at 4.3 A - Clamped voltage under 10/1000 μs surge; limits downstream IC stress to safe levels in automotive CAN or RS-485 lines. |
| PPPM | 400 W - Peak pulse power handling capacity; sustains repetitive 0.01% duty cycle surges per IEC 61000-4-5 Level 4 testing. |
| IPPM | 4.3 A - Peak pulse current capability; enables protection of medium-energy transients such as inductive switch-off in solenoid drivers. |
| TJ max. | +175 °C - Maximum junction temperature; supports under-hood automotive placement and high-ambient industrial environments. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including HTOL, TCT, and ESD testing; required for ECUs and ADAS sensor modules. |
Pinout & Package
DO-41 (DO-204AL) axial-leaded package with matte tin-plated leads; no polarity marking for bidirectional configuration - terminals are functionally interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | Either lead serves as input/output terminal; no cathode band - enables placement on AC or differential signal paths without orientation constraints. |
| Lead 1 / Lead 2 | Current path for transient conduction | Low-inductance axial structure minimizes voltage overshoot during fast-rising transients (tr < 1 ns); leads solderable per J-STD-002. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58CA | DO-214AA package; 58 V VWM, 93.6 V VC @ 4.3 A; same PPPM but lower IFSM (100 A vs. 40 A unidirectional only) | Surface-mount footprint; better suited for high-density PCBs but lacks AEC-Q101 qualification in standard grade | Select SMBJ58CA when board space is constrained and automotive qualification is not required. |
| 1.5KE56CA | DO-201AD package; 56 V VWM, 93.6 V VC @ 4.3 A; 1500 W PPPM but larger size and no AEC-Q101 rating | Higher energy handling for rare high-energy surges; incompatible with automated axial insertion due to larger body | Choose 1.5KE56CA only for non-automotive industrial systems needing >400 W single-event margin. |
Compared with SMBJ58CA and 1.5KE56CA, BZW04-58BHE3/54 uniquely combines AEC-Q101 qualification, DO-41 axial form factor for through-hole reliability, and optimized 400 W/92 V clamping performance for cost-sensitive automotive and industrial designs where manual assembly or vibration resistance is prioritized.

FAQ
What is the polarity configuration of BZW04-58BHE3/54?
BZW04-58BHE3/54 is a bidirectional TVS diode with symmetrical avalanche characteristics in both directions. It has no cathode marking and functions identically regardless of terminal orientation - making it ideal for AC-coupled or differential signal lines where polarity reversal may occur. This behavior is confirmed in the "BIDIRECTIONAL TYPES" table of the Vishay datasheet 88316.
Does BZW04-58BHE3/54 meet automotive qualification standards?
Yes, BZW04-58BHE3/54 carries the HE3 suffix, indicating full AEC-Q101 qualification per Vishay's documentation. This includes stress testing for high-temperature operating life, temperature cycling, and electrostatic discharge - validating its use in engine control units, ADAS sensors, and body electronics where reliability under thermal and mechanical stress is critical. The qualification is explicitly noted in the Mechanical Data section of datasheet 88316.
What is the maximum clamping voltage of BZW04-58BHE3/54 under surge conditions?
The maximum clamping voltage (VC) of BZW04-58BHE3/54 is 92.0 V at a peak pulse current (IPPM) of 4.3 A with a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during standardized surge events - essential for ensuring downstream ICs remain within absolute maximum ratings.
How does the HE3 suffix differ from the E3 suffix in BZW04-58BHE3/54?
The HE3 suffix in BZW04-58BHE3/54 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD201 class 2 whisker resistance. In contrast, the E3 suffix indicates commercial-grade RoHS compliance only, with JESD201 class 1A whisker testing. The HE3 variant is specifically intended for automotive and high-reliability industrial applications where extended thermal cycling and long-term tin whisker mitigation are required.
Can BZW04-58BHE3/54 be used in place of unidirectional TVS diodes?
No - BZW04-58BHE3/54 is strictly bidirectional and must not replace unidirectional TVS diodes in DC-biased applications such as power rail clamping, where forward conduction would cause short-circuit failure. Its symmetrical VBR and lack of polarity marking make it suitable only for AC, differential, or floating signal paths. Substitution requires verifying circuit topology and confirming absence of DC bias across the device.
