Product details
Overview
BZW04P10HE3/54 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 10.2 V stand-off voltage (VWM), 16.7 V maximum clamping voltage (VC) at 24.0 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) capability with 10/1000 μs waveform - ideal for safeguarding automotive-grade sensor interfaces and industrial control inputs against ESD and inductive switching transients.
For engineers reviewing the BZW04P10HE3/54 datasheet, BZW04P10HE3/54 pinout, BZW04P10HE3/54 application, or BZW04P10HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AL (DO-41) package, bi-directional symmetry, and verified clamping performance under repetitive surge conditions per IEC 61000-4-5.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance, enabling consistent clamping across repeated 10/1000 μs transients at 0.01% duty cycle.
The device is rated for 175 °C maximum junction temperature 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 - critical for automotive electronics reliability validation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 10.2 V - Maximum continuous working voltage before clamping initiates; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 11.4 V min / 13.2 V max at 1.0 mA - Tight tolerance ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 16.7 V at IPPM = 24.0 A - Limits voltage seen by protected ICs during 400 W surge events. |
| PPPM (Peak Pulse Power) | 400 W (10/1000 μs) - Sustains high-energy surges common in automotive load-dump and inductive kick scenarios. |
| ID (Reverse Leakage) | 1.0 μA at VWM - Negligible standby current preserves system efficiency in always-on circuits. |
| TJ max | 175 °C - Enables operation in under-hood automotive environments and high-ambient industrial settings. |
| Package | DO-204AL (DO-41) - Standard axial-leaded through-hole package compatible with legacy PCB assembly and manual repair. |
Pinout & Package
DO-204AL (DO-41) package: axial-leaded, molded epoxy case with matte tin-plated leads compliant to J-STD-002 and JESD22-B102. Bi-directional construction means no polarity marking; terminals are functionally identical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Bi-directional terminals conduct equally in either polarity to clamp positive or negative surges without orientation dependency. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics requiring long-term reliability under thermal cycling and vibration. |
| Glass passivated junction | Ensures stable VBR over time and temperature, minimizing parameter drift in harsh environments. |
| 400 W peak pulse power (10/1000 μs) | Handles high-energy transients from relay coil de-energization or motor commutation without degradation. |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes overvoltage stress on downstream components - critical for protecting 12 V rail logic and analog sensors. |
| JESD 201 Class 2 whisker resistance | Prevents tin whisker growth under thermal/humidity stress, eliminating latent short-circuit risk in sealed modules. |
Applications
| Automotive Sensor Protection | Industrial PLC Input Protection |
|---|---|

Use Value: Enables direct integration into compact white-goods PCBs without polarity concerns or additional rectification components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | Same DO-214AA package; lower PPPM (600 W), higher VC (17.0 V), wider VBR tolerance (11.1–12.3 V). | Surface-mount only; requires rework of layout and reflow process - not drop-in for through-hole designs. | Select when board space is constrained and SMT assembly is available; verify clamping margin against protected IC's absolute maximum ratings. |
| P6KE10CA | Higher PPPM (600 W), larger DO-15 package, slower response due to higher junction capacitance (~500 pF vs. ~100 pF for BZW04P10HE3/54). | Less suitable for high-speed signal lines; better for bulk power rail protection where capacitance is non-critical. | Choose for cost-sensitive industrial power supplies where footprint and speed are secondary to energy handling. |
Compared with SMBJ10CA and P6KE10CA, the BZW04P10HE3/54 offers optimal balance of axial-leaded compatibility, AEC-Q101 qualification, and low-clamp performance in compact DO-41 form - making it the preferred choice for automotive and industrial through-hole designs requiring validated reliability.

FAQ
What is the clamping voltage of BZW04P10HE3/54 at its rated peak pulse current?
The BZW04P10HE3/54 has a maximum clamping voltage (VC) of 16.7 V at 24.0 A peak pulse current (IPPM), measured under standardized 10/1000 μs waveform conditions. This value ensures protected downstream components - such as 12 V-rated microcontrollers or analog front-ends - remain within safe operating limits during surge events. The clamping performance is guaranteed across the full operating temperature range and is integral to the device's AEC-Q101 qualification.
Is BZW04P10HE3/54 unidirectional or bidirectional?
BZW04P10HE3/54 is a bi-directional transient voltage suppressor, indicated by the "B" suffix implicitly included in its functional designation (though omitted in the part number string itself). Its electrical characteristics - including VBR, VC, and ID - apply identically in both polarities, and it carries no polarity marking on the DO-41 package. This symmetry enables straightforward placement across AC-coupled lines or differential buses without orientation constraints.
Does BZW04P10HE3/54 meet automotive qualification standards?
Yes, BZW04P10HE3/54 is explicitly AEC-Q101 qualified, as confirmed by the "HE3" suffix in its ordering code. This qualification covers stress tests including high-temperature operating life, temperature cycling, mechanical shock, and humidity bias, validating its suitability for automotive powertrain, chassis, and body electronics. The device also meets JESD 201 Class 2 whisker resistance and RoHS Directive 2011/65/EU compliance.
What is the maximum junction temperature rating for BZW04P10HE3/54?
The BZW04P10HE3/54 has a maximum junction temperature (TJ max) of +175 °C, enabling reliable operation in high-ambient environments such as engine compartments or enclosed industrial enclosures. This rating is supported by its glass-passivated chip junction and DO-204AL package construction, and derating curves in the Vishay datasheet (Document 88316, Fig. 2 and Fig. 5) define allowable power dissipation versus ambient temperature.
How does the HE3 suffix differ from the E3 suffix in BZW04P10 variants?
The HE3 suffix in BZW04P10HE3/54 denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas the E3 suffix (e.g., BZW04P10-E3/54) indicates RoHS compliance and commercial-grade qualification only. Both share identical electrical specs and DO-41 packaging, but HE3 is required for automotive applications demanding extended reliability validation - including accelerated lifetime testing and failure mode analysis per AEC standards.
