Product details
Overview
BZW04P14B-E3/73 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 13.6 V stand-off voltage (VWM), 22.5 V clamping voltage (VC) at 17.8 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the BZW04P14B-E3/73 datasheet, BZW04P14B-E3/73 pinout, BZW04P14B-E3/73 application, or BZW04P14B-E3/73 equivalent, key selection criteria include its bi-directional clamping symmetry, AEC-Q101 qualification, DO-204AL (DO-41) package compatibility, low 0.086 %/°C VBR temperature coefficient, and 1.0 μA max reverse leakage at VWM.
Technical Context
This bi-directional TVS diode uses a glass passivated chip junction to deliver symmetrical clamping in both polarities, enabling protection of AC-coupled or floating signal paths without polarity concerns. Its 10/1000 μs surge response supports IEC 61000-4-5 Level 3/4 compliance when properly laid out with low-inductance traces.
The device operates across –55 °C to +175 °C junction temperature range and maintains stable breakdown behavior with only 0.086 %/°C VBR drift. It is rated for 1.5 W steady-state power dissipation on an infinite heatsink at TL = 75 °C and withstands solder dip up to 275 °C for 10 s per JESD 22-B106.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13.6 V - maximum continuous reverse operating voltage before clamping begins; defines safe working margin below breakdown. |
| VBR min/max | 15.2 V / 17.6 V at 1.0 mA - guaranteed breakdown onset range; ensures predictable turn-on during transients. |
| VC @ IPPM | 22.5 V at 17.8 A - clamped voltage under 10/1000 μs surge; determines protected circuit's maximum stress level. |
| PPPM | 400 W - peak pulse power handling with 10/1000 μs waveform; validates immunity to common lightning/inductive spikes. |
| ID @ VWM | 1.0 μA - max reverse leakage at stand-off voltage; minimizes quiescent power loss and signal distortion. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ14CA | Same DO-214AA package; 14 V VWM, 23.2 V VC @ 17.2 A; lower PPPM (600 W vs. 400 W), higher capacitance (~150 pF). | Better suited for high-speed data lines where lower clamping voltage is critical; less optimal for high-temp automotive under-hood use due to 150 °C TJ max. | Select SMBJ14CA if board space allows SMD footprint and lower VC is prioritized over AEC-Q101 qualification. |
| P6KE15CA | DO-15 package; 15 V VWM, 24.4 V VC @ 16.4 A; same 400 W PPPM but larger body size and 150 °C TJ max. | Legacy through-hole alternative with higher thermal mass; lacks AEC-Q101 qualification and RoHS-compliant lead finish per JESD 201 Class 1A. | Choose P6KE15CA only for cost-sensitive industrial replacements where AEC-Q101 and whisker resistance are not required. |
Compared with SMBJ14CA and P6KE15CA, BZW04P14B-E3/73 uniquely combines AEC-Q101 qualification, DO-41 axial form factor, 175 °C junction rating, and JESD 201 Class 1A whisker resistance - making it the preferred choice for new automotive and high-reliability industrial designs requiring proven long-term stability.

FAQ
What is the clamping voltage of BZW04P14B-E3/73 under a 10/1000 μs surge?
The BZW04P14B-E3/73 clamps to a maximum of 22.5 V when subjected to its rated 17.8 A peak pulse current with a 10/1000 μs waveform. This value is measured per IEC 61000-4-5 test conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The BZW04P14B-E3/73 maintains this clamping performance across its full operating temperature range.
Is BZW04P14B-E3/73 suitable for automotive applications?
Yes, BZW04P14B-E3/73 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its 175 °C maximum junction temperature, glass passivated junction, and JESD 201 Class 1A whisker-resistant matte tin leads meet stringent automotive reliability requirements. The BZW04P14B-E3/73 is commonly deployed in engine control units, body control modules, and ADAS sensor interfaces.
Does BZW04P14B-E3/73 have polarity markings?
No, BZW04P14B-E3/73 is a bi-directional TVS diode and carries no polarity marking on its DO-204AL (DO-41) package. Both leads are functionally identical, allowing unrestricted orientation during placement. This symmetry enables straightforward integration into AC-coupled or floating signal paths without concern for anode/cathode alignment. The BZW04P14B-E3/73 behaves identically regardless of voltage polarity applied.
What is the maximum reverse leakage current for BZW04P14B-E3/73 at its stand-off voltage?
The BZW04P14B-E3/73 exhibits a maximum reverse leakage current (ID) of 1.0 μA at its 13.6 V stand-off voltage (VWM) and 25 °C ambient temperature. This ultra-low leakage preserves signal integrity in high-impedance analog circuits and avoids unnecessary power drain in battery-operated systems. The BZW04P14B-E3/73 maintains tight leakage control across its full –55 °C to +175 °C operating range.
How does the temperature coefficient affect BZW04P14B-E3/73's breakdown voltage?
The BZW04P14B-E3/73 has a maximum temperature coefficient of 0.086 %/°C for its breakdown voltage (VBR), meaning VBR increases by up to 0.086 % per degree Celsius rise in junction temperature. This low drift ensures stable clamping onset across wide thermal ranges - critical for automotive and industrial applications. The BZW04P14B-E3/73's predictable VBR shift supports accurate system-level surge margin analysis without derating overhead.
