Product details
Overview
BZW04P11HE3/54 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 11.1 V stand-off voltage (VWM), 12.4–14.3 V breakdown voltage (VBR at 1 mA), 18.2 V clamping voltage (VC) at 22 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - deployed to safeguard MOSFETs, ICs, and sensor interfaces against ESD and inductive switching transients.
For engineers reviewing the BZW04P11HE3/54 datasheet, BZW04P11HE3/54 pinout, BZW04P11HE3/54 application, or BZW04P11HE3/54 equivalent, key selection considerations include its AEC-Q101 qualification, DO-204AL (DO-41) axial package, bi-directional polarity, 175 °C max junction temperature, and compliance with IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT) immunity requirements.
Technical Context
This bi-directional TVS operates symmetrically in both polarities, delivering consistent clamping performance without polarity sensitivity. Its glass-passivated junction ensures stable leakage (<1 µA at VWM) and low incremental surge resistance, enabling fast response (<1 ns) to transients while maintaining low capacitance (typ. <100 pF at VWM).
The device is rated for 400 W peak pulse power under 10/1000 µs waveform with 0.01% duty cycle, derated linearly above 25 °C per Fig. 2, and supports soldering up to 275 °C for 10 s (JESD 22-B106). The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11.1 V - Maximum continuous reverse working voltage before significant conduction begins; defines safe operating margin below breakdown. |
| VBR (min/max) | 12.4 V / 14.3 V at 1 mA - Confirmed breakdown range ensuring reliable turn-on during transients without premature triggering. |
| VC @ IPPM | 18.2 V at 22 A - Clamped voltage during 10/1000 µs surge; limits downstream voltage stress to protected circuitry. |
| PPPM | 400 W - Peak pulse power handling capacity; enables suppression of high-energy transients common in automotive and industrial environments. |
| IPPM | 22 A - Peak pulse current capability under standard 10/1000 µs waveform; directly correlates with surge energy absorption (E ≈ 0.4 × VC × IPPM × t). |
| TJmax | 175 °C - Maximum junction temperature; supports operation in under-hood automotive and high-ambient industrial applications. |
| Package | DO-204AL (DO-41) - Standard axial-leaded package with 0.205" body diameter; compatible with through-hole assembly and manual rework. |
Pinout & Package
DO-204AL (DO-41) molded epoxy package with matte tin-plated leads; bi-directional construction means no polarity marking - both terminals are functionally identical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Bi-directional operation: either terminal serves as anode or cathode depending on transient polarity; no color band or marking required. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock - suitable for engine control, body electronics, and ADAS sensors. |
| Glass passivated junction | Ensures stable VBR tolerance and low leakage (<1 µA at VWM) across temperature and lifetime, critical for low-power sensor interfaces. |
| 400 W peak pulse power (10/1000 µs) | Provides robust protection against ISO 7637-2 Pulse 1/2a/3a and IEC 61000-4-4 EFT bursts without thermal runaway. |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes let-through voltage during clamping - reduces risk of latch-up or damage to downstream CMOS logic and analog front-ends. |
| RoHS-compliant, JESD 201 Class 2 whisker resistant | Meets automotive supply chain requirements for lead-free assembly and long-term interconnect reliability in vibration-prone environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11CA | Same DO-214AA package; higher VC (19.9 V at 21.6 A); lower PPPM (600 W but derated faster above 25 °C). | Less suitable for tight-clamp designs where 18.2 V ceiling is critical; better for space-constrained PCBs needing surface-mount. | Select SMBJ11CA only if SMT layout is mandatory and clamping margin allows +1.7 V overhead. |
| 1.5KE11CA | Higher PPPM (1500 W), larger DO-201AD package; VC = 18.2 V same, but slower response due to higher junction capacitance (~150 pF). | Preferred for high-energy lightning protection; unsuitable for high-speed data lines due to bandwidth limitation. | Choose 1.5KE11CA when protecting AC mains inputs or relay coils - not for signal integrity-critical paths. |
Compared with SMBJ11CA and 1.5KE11CA, BZW04P11HE3/54 offers optimal balance of compact DO-41 form factor, AEC-Q101 qualification, and precise 18.2 V clamping - making it the preferred choice for automotive and industrial signal-line protection where reliability, size, and voltage margin are jointly constrained.

FAQ
What is the maximum clamping voltage of BZW04P11HE3/54 under surge conditions?
The BZW04P11HE3/54 has a maximum clamping voltage (VC) of 18.2 V at 22 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured per IEC 61000-4-5 test conditions and represents the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring compatibility with 5 V or 3.3 V logic interfaces.
Is BZW04P11HE3/54 suitable for automotive applications?
Yes, BZW04P11HE3/54 is AEC-Q101 qualified and carries the HE3 suffix denoting compliance with automotive reliability standards including temperature cycling, mechanical shock, and whisker resistance (JESD 201 Class 2). It is widely used in engine control units, body control modules, and ADAS sensor interfaces where sustained operation up to 175 °C junction temperature is required.
How does the bi-directional nature of BZW04P11HE3/54 affect its placement in circuit design?
Because BZW04P11HE3/54 is bi-directional, it has no polarity marking and can be installed in either orientation across protected lines - simplifying layout and eliminating risk of reverse installation. This symmetry makes it ideal for AC-coupled signals, differential buses like LIN or RS-485, and any application where voltage transients may occur with either polarity relative to ground.
What is the standoff voltage (VWM) specification for BZW04P11HE3/54, and why is it important?
The standoff voltage (VWM) of BZW04P11HE3/54 is 11.1 V - the maximum DC or continuous peak voltage the device blocks without entering avalanche conduction. This parameter ensures normal circuit operation remains unaffected while providing sufficient margin below the 12.4–14.3 V breakdown range, preventing false triggering during nominal voltage fluctuations or ripple.
Does BZW04P11HE3/54 require heatsinking in typical applications?
No, BZW04P11HE3/54 does not require external heatsinking for transient suppression duty cycles (e.g., 0.01% for 10/1000 µs pulses). Its 1.5 W steady-state power dissipation (PD) is sufficient for leakage current handling at VWM, and thermal design relies on PCB copper area for short-duration pulse energy dissipation - verified per Vishay's Fig. 5 derating curve.
