Product details
Overview
BZW04-128HE3/54 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 128 V standoff voltage (VWM), 143–158 V breakdown range (VBR at 1 mA), 207 V clamping voltage (VC) at 2.0 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 BZW04-128HE3/54 datasheet, BZW04-128HE3/54 pinout, BZW04-128HE3/54 application, or BZW04-128HE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-41 mechanical data, clamping performance under surge conditions, and direct alternatives for board-level ESD/transient hardening.
Technical Context
This device operates bidirectionally with symmetrical breakdown and clamping characteristics in both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and low incremental surge resistance, critical for repeatable transient suppression across temperature.
The BZW04-128HE3/54 is rated for 175 °C maximum junction temperature and supports 8.3 ms half-sine surge handling up to 40 A (unidirectional only; not applicable here due to bidirectional configuration). Its 0.108 %/°C VBR temperature coefficient ensures predictable voltage drift over automotive operating ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 128 V - Maximum continuous reverse working voltage before conduction begins; defines safe operating margin for protected line. |
| VBR (min/max) | 143 V / 158 V at 1 mA - Verified breakdown threshold range; ensures reliable triggering above normal transients but below system damage thresholds. |
| VC @ IPPM | 207 V at 2.0 A - Clamped voltage during 10/1000 µs surge; limits downstream IC stress to sub-210 V level. |
| PPPM | 400 W - Peak pulse power handling capability; sustains standardized lightning/surge events per IEC 61000-4-5. |
| ID @ VWM | <1.0 µA - Ultra-low reverse leakage at rated standoff; prevents signal distortion or bias shift in high-impedance circuits. |
| TJ max. | 175 °C - Enables operation in under-hood automotive environments and industrial enclosures without derating. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |

| Telecom Line Interface | Consumer Appliance Power Supply |
Use Scenario: Shielding RS-485 transceivers and Ethernet PHYs in base station backhaul equipment from lightning-induced longitudinal surges on twisted-pair lines. IC Role / Device Role / Timing Role: Paired bidirectional TVS devices on differential pairs (A/B lines), with low capacitance preserving signal integrity. Use Value: Clamps common-mode transients to <210 V while adding <10 pF junction capacitance at 0 V, minimizing bit error rate impact. | Use Scenario: Suppressing switch-mode power supply turn-off spikes and ESD events on AC mains input stages of washing machines and HVAC controllers. IC Role / Device Role / Timing Role: Across-line (L–N) and line-to-ground (L–G/N–G) placement for Class II isolated supplies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | Unidirectional; 130 V VWM; DO-214AA package; 600 W PPPM; higher IPPM (3.3 A) | Requires polarity-aware layout; better suited for DC-biased rails where reverse conduction must be blocked. | Select when unidirectional blocking is mandatory and PCB space allows SMC/SMB footprint. |
| P6KE130A | Unidirectional; 130 V VWM; DO-15 package; 600 W PPPM; 3.3 A IPPM; slower response than BZW04 series | Larger DO-15 body; lower surge repetition tolerance; not AEC-Q101 qualified. | Choose for legacy designs using DO-15 footprints or non-automotive cost-sensitive applications. |
Compared with BZW04-128HE3/54, SMBJ130A offers higher pulse power but requires polarity-aware routing and lacks AEC-Q101 validation, while P6KE130A provides similar voltage rating in a larger DO-15 package without automotive qualification or low-leakage performance.

FAQ
What is the polarity configuration of BZW04-128HE3/54?
BZW04-128HE3/54 is a bidirectional TVS diode, meaning it provides symmetrical clamping in both forward and reverse directions. Per Vishay documentation, bidirectional types like BZW04-128HE3/54 have no polarity marking on the DO-41 package - both leads are functionally identical for transient suppression across AC or floating lines.
Is BZW04-128HE3/54 qualified for automotive use?
Yes, BZW04-128HE3/54 carries the HE3 suffix, which denotes RoHS-compliant construction and full AEC-Q101 qualification per Vishay's ordering information and mechanical data section. This validates its suitability for automotive powertrain, chassis, and body electronics applications requiring extended temperature operation and long-term reliability.
What is the clamping voltage of BZW04-128HE3/54 under surge conditions?
The maximum clamping voltage (VC) of BZW04-128HE3/54 is 207 V at 2.0 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during transient events.
How does the HE3 suffix differ from E3 in BZW04 part numbering?
The HE3 suffix in BZW04-128HE3/54 indicates AEC-Q101 qualification and RoHS compliance, whereas E3 denotes RoHS compliance only for commercial-grade parts. HE3 devices undergo additional stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD validation required for automotive deployment.
What package type does BZW04-128HE3/54 use, and what are its key mechanical attributes?
BZW04-128HE3/54 uses the DO-41 (DO-204AL) axial-leaded package: molded epoxy housing over a glass-passivated chip, UL 94 V-0 rated, with matte tin-plated leads solderable per J-STD-002. Its dimensions are 25.4 mm minimum length and 2.0–2.7 mm diameter, supporting through-hole assembly and 275 °C solder dip tolerance.
