Product details
Overview
BZW04-13HE3/54 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 12.8 V stand-off voltage (VWM), 14.3–15.8 V breakdown voltage (VBR) at 1 mA test current, 21.2 V clamping voltage (VC) at 19.0 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the BZW04-13HE3/54 datasheet, BZW04-13HE3/54 pinout, BZW04-13HE3/54 application, or BZW04-13HE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-41 mechanical data, clamping performance under surge conditions, and direct alternatives for ESD/transient-hardened designs.
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 VBR tolerance and low leakage (<1.0 μA at VWM), while the 175 °C maximum junction temperature supports operation in under-hood automotive environments.
The 400 W peak pulse rating is specified per 10/1000 μs waveform at TA = 25 °C and derates linearly above 25 °C per Vishay's Fig. 2 curve. Clamping voltage VC = 21.2 V at IPPM = 19.0 A confirms low incremental surge resistance, critical for limiting transient energy delivered to downstream ICs like microcontrollers or CAN transceivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 12.8 V - Maximum continuous reverse working voltage before conduction begins; defines safe operating margin below system rail or signal swing. |
| VBR min/max | 14.3 V / 15.8 V at IT = 1 mA - Tight breakdown window ensures predictable turn-on during transients without premature leakage. |
| VC @ IPPM | 21.2 V at 19.0 A - Clamping voltage limits stress on protected circuitry; 8.4 V overshoot above VWM provides headroom for fast-rising surges. |
| PPPM | 400 W - Peak transient energy absorption capability with 10/1000 μs waveform; sufficient for ISO 7637-2 Pulse 1/2a/3a and IEC 61000-4-5 Level 3. |
| ID @ VWM | <1.0 μA - Ultra-low reverse leakage preserves signal integrity and battery life in always-on sensor nodes. |
| TJ max | +175 °C - Enables placement near heat sources (e.g., engine control units) without thermal derating concerns. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; no polarity marking for bidirectional operation; matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative half-cycle) | Conducts during negative-going surges; symmetric with cathode due to bidirectional structure. |
| Cathode | Transient current entry (positive half-cycle) | Conducts during positive-going surges; identical clamping behavior as anode per bidirectional design. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR over lifetime and temperature; eliminates risk of junction degradation under repeated surge stress. |
| 400 W 10/1000 μs rating | Supports high-energy transients common in 12 V automotive systems (e.g., load dump suppression up to ISO 16750-2). |
| AEC-Q101 qualification | Validates suitability for automotive applications including powertrain, body electronics, and ADAS sensor modules. |
| UL 94 V-0 molding compound | Provides flame-retardant encapsulation required for safety-critical PCB layouts in enclosed enclosures. |
| JESD201 class 2 whisker resistance | HE3 suffix guarantees lead finish stability under thermal cycling, preventing tin whisker growth in long-life deployments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | DO-214AA package (SMB), 13 V VWM, same 400 W rating but higher VC = 21.5 V; lower parasitic capacitance (≈150 pF vs. ≈200 pF). | Suitable for high-speed data lines where lower capacitance is critical; less robust mechanical mounting than axial DO-41 in vibration-prone environments. | Select SMBJ13CA when board space is constrained and layout allows surface-mount assembly; prefer BZW04-13HE3/54 for through-hole reliability in automotive harness interfaces. |
| P6KE13CA | DO-15 package, same VWM/VC specs, but only 600 W rating (10/1000 μs); larger footprint and higher thermal resistance. | Better suited for legacy industrial designs using DO-15 footprints; not AEC-Q101 qualified - unsuitable for automotive use cases. | Choose P6KE13CA only for cost-sensitive commercial equipment where AEC-Q101 is not mandated and higher pulse power margin is needed. |
Compared with SMBJ13CA and P6KE13CA, the BZW04-13HE3/54 offers AEC-Q101 qualification in a compact DO-41 axial package with proven reliability in automotive sensor nodes, while balancing clamping performance, thermal robustness, and manufacturability in wave-soldered assemblies.

FAQ
What is the clamping voltage of the BZW04-13HE3/54 under maximum surge conditions?
The BZW04-13HE3/54 has a maximum clamping voltage (VC) of 21.2 V at 19.0 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per JEDEC standards and reflects the actual voltage seen by protected circuitry during worst-case transient events. The BZW04-13HE3/54 maintains this clamping performance across its full operating temperature range (-55 °C to +175 °C), ensuring consistent protection in demanding environments.
Is the BZW04-13HE3/54 suitable for automotive applications?
Yes, the BZW04-13HE3/54 is AEC-Q101 qualified, confirming its reliability for automotive use including engine control units, body electronics, and ADAS sensor modules. Its DO-41 package with JESD201 class 2 whisker resistance, UL 94 V-0 molding, and 175 °C junction rating meet stringent automotive environmental requirements. The BZW04-13HE3/54 is explicitly rated for load dump and inductive switching transients common in 12 V vehicle systems.
How does the HE3 suffix differ from the E3 suffix in BZW04-13HE3/54?
HE3 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD201 class 2 whisker resistance, whereas E3 denotes RoHS compliance and JESD201 class 1A whisker testing only (commercial grade). The BZW04-13HE3/54 is therefore validated for automotive deployment, while BZW04-13E3/54 is intended for commercial applications. Both share identical electrical specs, but the HE3 suffix guarantees extended reliability under thermal cycling and vibration stress.
What is the reverse leakage current of the BZW04-13HE3/54 at its stand-off voltage?
The BZW04-13HE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA at its 12.8 V stand-off voltage (VWM) and TA = 25 °C. This ultra-low leakage preserves signal fidelity in high-impedance sensor circuits and minimizes quiescent power loss in battery-powered systems. Leakage remains below 5.0 μA across the full -55 °C to +125 °C operating range, as confirmed in Vishay's characterization data.
Can the BZW04-13HE3/54 be used in bidirectional signal line protection?
Yes, the BZW04-13HE3/54 is a bidirectional TVS diode - denoted by the absence of polarity marking and symmetric VBR/VC specifications in both directions. It protects AC-coupled or floating differential pairs (e.g., RS-485, CAN, USB D+/D−) without requiring orientation awareness during placement. The BZW04-13HE3/54 delivers identical clamping performance for positive and negative transients, making it ideal for full-duplex communication interfaces.
