Product details
Overview
BZW04P13HE3/54 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 12.8 V stand-off voltage (VWM), 14.3–16.5 V breakdown voltage (VBR), 21.2 V clamping voltage (VC) at 19.0 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the BZW04P13HE3/54 datasheet, BZW04P13HE3/54 pinout, BZW04P13HE3/54 application, or BZW04P13HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AL (DO-41) package, bi-directional symmetry, low clamping ratio (VC/VBR ≈ 1.42), and suitability for inductive switching surge suppression in harsh environments.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, enabling single-device protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable leakage performance and fast response (<1 ns), while the 10/1000 μs surge rating reflects standardized lightning and EFT immunity testing conditions.
The device is rated for continuous operation from –55 °C to +175 °C junction temperature and supports repetitive surge events at ≤0.01% duty cycle. Its 1.5 W steady-state power dissipation (PD) and 1.0 mA test current (IT) define DC biasing limits, and the 0.084 %/°C VBR temperature coefficient indicates moderate thermal drift in breakdown voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 12.8 V - maximum continuous reverse working voltage before significant conduction begins; defines safe operating margin below clamping threshold. |
| VBR (min/max) | 14.3 V / 16.5 V at 1.0 mA - guaranteed breakdown onset range; ensures predictable turn-on during transients. |
| VC @ IPPM | 21.2 V at 19.0 A - clamped voltage under 10/1000 μs surge; determines maximum stress imposed on protected circuitry. |
| PPPM | 400 W - peak pulse power handling capability; validates robustness against IEC 61000-4-5 Level 4 surges. |
| ID @ VWM | 1.0 μA - reverse leakage current at stand-off voltage; critical for low-power sensor and battery-backed circuits. |

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 | Same DO-214AA package; 13 V VWM, 21.5 V VC @ 19.1 A; lower PPPM (600 W), higher capacitance (~150 pF). | Higher junction capacitance limits use in >10 Mbps data lines; better suited for power rail vs. high-speed signal protection. | Select SMBJ13CA only when board space requires SMC/SMB footprint and higher steady-state power derating is acceptable. |
| 1.5KE13CA | DO-201AD package; same 13 V VWM, 21.2 V VC @ 19.0 A; higher PPPM (1500 W), larger form factor, slower response due to higher parasitic inductance. | Preferred for high-energy AC mains protection; unsuitable for compact PCB layouts or fast-edge signal lines. | Choose 1.5KE13CA where surge energy exceeds 400 W but layout allows axial-to-radial conversion and thermal mass permits larger case. |
Compared with BZW04P13HE3/54, SMBJ13CA offers higher surge rating but compromises signal integrity in high-frequency applications, while 1.5KE13CA delivers greater energy absorption at the cost of size and speed - making BZW04P13HE3/54 optimal for space-constrained, AEC-Q101–required bi-directional protection.

FAQ
What is the clamping voltage of BZW04P13HE3/54 under a 10/1000 μs surge?
The BZW04P13HE3/54 clamps to a maximum of 21.2 V when subjected to its rated 19.0 A peak pulse current 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 surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is BZW04P13HE3/54 suitable for automotive applications?
Yes, BZW04P13HE3/54 is AEC-Q101 qualified and manufactured with HE3 suffix indicating full compliance with automotive reliability testing including temperature cycling, highly accelerated life testing (HALT), and ESD robustness. Its –55 °C to +175 °C operating range and bi-directional symmetry make it appropriate for engine control units, body electronics, and ADAS sensor protection in passenger and commercial vehicles.
How does the bi-directional nature of BZW04P13HE3/54 affect PCB layout?
The bi-directional design of BZW04P13HE3/54 eliminates polarity marking - both leads are functionally identical, allowing placement without orientation verification. This simplifies automated assembly and reduces risk of misorientation-related field failures, especially in high-density layouts where visual inspection is limited. No silkscreen polarity indicator is required.
What is the maximum steady-state power dissipation for BZW04P13HE3/54?
The BZW04P13HE3/54 has a maximum steady-state power dissipation (PD) of 1.5 W when mounted on an infinite heatsink at lead temperature (TL) = 75 °C. Derating follows the curve in Figure 5 of Vishay document 88316, reducing to ~0.75 W at TL = 125 °C - important for thermal design in enclosed enclosures or high-ambient environments.
Does BZW04P13HE3/54 meet RoHS and REACH requirements?
Yes, BZW04P13HE3/54 carries the HE3 suffix, confirming RoHS Directive 2011/65/EU compliance and adherence to Vishay's Material Category Policy. It contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits, and full substance declarations are available via Vishay's compliance portal upon request.
