Overview
BZW04P5V8HE3/54 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode designed for robust overvoltage protection on signal and power lines. It features a 5.8 V stand-off voltage (VWM), 10.5 V clamping voltage (VC) at 38 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 circuits.
For engineers reviewing the BZW04P5V8HE3/54 datasheet, BZW04P5V8HE3/54 pinout, BZW04P5V8HE3/54 application, or BZW04P5V8HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, DO-41 package compatibility, low 0.057 %/°C VBR temperature coefficient, and verified performance under repetitive 0.01 % duty cycle surges per JESD22-B106 soldering conditions.
Technical Context
This bi-directional TVS operates symmetrically in both polarities, with breakdown voltage (VBR) specified between 6.45 V and 7.48 V at 10 mA test current. Its clamping behavior limits transients to ≤10.5 V at 38 A IPPM, enabling reliable protection of downstream MOSFET gates and microcontroller I/O pins against ESD and inductive switching spikes.
The device uses a glass-passivated chip junction and meets UL 94 V-0 flammability requirements in its DO-204AL (DO-41) epoxy package. Thermal derating follows Fig. 2, maintaining 400 W capability up to TJ = 25 °C and supporting continuous operation from –55 °C to +175 °C junction temperature.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-E3/52 | Unidirectional; 5.0 V VWM; SMB package (surface-mount); 600 W PPPM | Requires polarity-aware layout; better suited for PCB space-constrained designs with automated assembly | Select when board real estate is limited and unidirectional protection suffices with added series impedance |
| P6KE6.8A | Unidirectional; 6.8 V VWM; DO-15 package; 600 W PPPM; no AEC-Q101 qualification | Lacks automotive qualification and JESD201 whisker testing; higher VC (10.5 V same, but higher IPPM tolerance) | Acceptable for commercial industrial use where AEC-Q101 is not mandated and lead-free reflow is not required |
Compared with BZW04P5V8HE3/54, SMBJ5.0A-E3/52 offers higher surge rating in a smaller footprint but requires polarity management, while P6KE6.8A delivers comparable clamping with greater pulse margin but lacks automotive qualification and modern whisker resistance - making BZW04P5V8HE3/54 the preferred choice for AEC-Q101-compliant, through-hole, bi-directional protection.

FAQ
What is the clamping voltage of BZW04P5V8HE3/54 and how does it protect downstream circuitry?
The BZW04P5V8HE3/54 has a maximum clamping voltage (VC) of 10.5 V at 38 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This ensures that any transient exceeding the 5.8 V stand-off voltage is limited to ≤10.5 V, protecting 5 V logic interfaces, microcontroller GPIOs, and analog front-ends from destructive overvoltage. The low incremental surge resistance contributes to consistent clamping performance across multiple surge events.
Is BZW04P5V8HE3/54 suitable for automotive applications?
Yes, BZW04P5V8HE3/54 is AEC-Q101 qualified and carries the HE3 suffix, indicating compliance with JESD201 class 2 whisker testing and RoHS requirements. It is rated for operation from –55 °C to +175 °C and validated for automotive environments including under-hood sensor modules, body control units, and infotainment system I/O protection.
How does the bi-directional nature of BZW04P5V8HE3/54 affect its usage compared to unidirectional TVS diodes?
BZW04P5V8HE3/54 conducts identically in both directions, eliminating polarity concerns during placement and enabling use on AC-coupled or differential signal lines without orientation checks. Unlike unidirectional TVS diodes such as P6KE6.8A, it requires no cathode marking and simplifies layout for bidirectional interfaces like RS-485, CAN, or audio lines - though it cannot replace unidirectional parts in DC-biased circuits requiring forward conduction blocking.
What is the significance of the HE3 suffix in BZW04P5V8HE3/54?
The HE3 suffix denotes that BZW04P5V8HE3/54 is RoHS-compliant and AEC-Q101 qualified, with matte tin-plated leads meeting JESD201 class 2 whisker resistance requirements. This distinguishes it from the base E3 version (commercial grade only) and confirms suitability for automotive and high-reliability industrial applications where long-term intermetallic growth must be mitigated.
Can BZW04P5V8HE3/54 be used in parallel to increase surge current handling?
No - BZW04P5V8HE3/54 should not be paralleled without external balancing resistors due to VBR mismatch between units, which causes uneven current sharing and potential thermal runaway. For higher IPPM requirements, select a single higher-rated device (e.g., BZW04P6V4HE3/54 or SMBJ series) or consult Vishay's application note AN8002 for derated parallel configurations with matched lots.
