Product details
Overview
BZW04P9V4HE3/54 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 9.4 V stand-off voltage (VWM), 15.6 V clamping voltage (VC) at 25.7 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 protection, and telecom line conditioning.
For engineers reviewing the BZW04P9V4HE3/54 datasheet, BZW04P9V4HE3/54 pinout, BZW04P9V4HE3/54 application, or BZW04P9V4HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AL (DO-41) package, bi-directional symmetry, low 0.075 %/°C VBR temperature coefficient, and compliance with IEC 61000-4-2/4-4/4-5 surge immunity requirements.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction delivers fast response time (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 μs transients at 0.01 % duty cycle.
The device is rated for -55 °C to +175 °C operating junction temperature, supports 1.5 W steady-state power dissipation at TL = 75 °C, and meets JESD22-B106 solderability (275 °C, 10 s) and JESD201 class 2 whisker resistance (HE3 suffix).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.4 V - maximum continuous reverse working voltage before clamping initiates; defines safe operating margin below breakdown. |
| VBR min/max | 10.5 V / 12.1 V at 1 mA - verified breakdown threshold range ensures consistent turn-on across production lots. |
| VC @ IPPM | 15.6 V at 25.7 A - clamping voltage under 10/1000 μs surge; limits downstream IC stress during ESD/EFT events. |
| PPPM | 400 W - peak pulse power handling per 10/1000 μs waveform; supports IEC 61000-4-5 Level 4 (4 kV) surge protection. |
| ID @ VWM | 5.0 µA - ultra-low reverse leakage at stand-off voltage; preserves signal integrity in high-impedance sensor circuits. |
| TJ max | +175 °C - extended junction temperature rating enables use in under-hood automotive and industrial 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 |
|---|---|---|---|
| SMBJ9.0CA | DO-214AA package; 9.0 V VWM; 16.7 V VC @ 24.0 A; same 400 W PPPM rating. | Surface-mount footprint requires PCB redesign; higher thermal resistance than axial DO-41 in free-air conditions. | Select when board space is constrained and reflow assembly is preferred over through-hole mounting. |
| P6KE9.1CA | DO-15 package; 9.1 V VWM; 15.3 V VC @ 26.0 A; 600 W PPPM (10/1000 μs); larger case size. | Higher surge capacity suits legacy industrial designs with >4 kV IEC 61000-4-5 requirements; not AEC-Q101 qualified. | Choose for non-automotive applications needing extra margin on peak current or where DO-15 is already standardized. |

FAQ
What is the clamping voltage of BZW04P9V4HE3/54 under a 10/1000 μs surge?
The BZW04P9V4HE3/54 clamps to a maximum of 15.6 V when subjected to its rated peak pulse current of 25.7 A using the standard 10/1000 μs waveform. This value is measured per IEC 61000-4-5 test conditions and ensures downstream circuitry remains within safe operating limits during surge events. The BZW04P9V4HE3/54 maintains this clamping performance across its full operating temperature range.
Is BZW04P9V4HE3/54 suitable for automotive applications?
Yes, BZW04P9V4HE3/54 is AEC-Q101 qualified and specifically designed for automotive use cases including engine control units, body electronics, and ADAS sensor interfaces. Its DO-204AL package, -55 °C to +175 °C operating range, and validation across HTOL, temperature cycling, and mechanical shock tests confirm suitability for under-hood and chassis-mounted deployments. The BZW04P9V4HE3/54 meets stringent automotive reliability requirements without derating.
How does the HE3 suffix affect BZW04P9V4HE3/54's compliance and reliability?
The HE3 suffix on BZW04P9V4HE3/54 indicates RoHS compliance and AEC-Q101 qualification, with additional validation to JESD201 class 2 whisker resistance. This ensures long-term solder joint integrity in high-reliability applications and compatibility with lead-free reflow processes. Unlike commercial-grade E3 variants, the HE3 version guarantees automotive-grade screening and traceability - critical for BZW04P9V4HE3/54 deployment in safety-critical systems.
What is the reverse leakage current of BZW04P9V4HE3/54 at its stand-off voltage?
At its 9.4 V stand-off voltage (VWM) and TA = 25 °C, the BZW04P9V4HE3/54 exhibits a maximum reverse leakage current (ID) of 5.0 µA. This ultra-low leakage preserves signal integrity in high-impedance sensor circuits and minimizes standby power loss in battery-powered systems. The BZW04P9V4HE3/54 maintains leakage below 10 µA even at elevated temperatures up to +125 °C.
Can BZW04P9V4HE3/54 be used in bi-directional signal lines without polarity concerns?
Yes, BZW04P9V4HE3/54 is a bi-directional TVS diode with symmetrical electrical characteristics in both polarities - no cathode marking, no polarity dependency. It is ideal for protecting AC-coupled interfaces, differential buses (e.g., RS-485, CAN), or floating sensor outputs where voltage transients may occur in either direction. The BZW04P9V4HE3/54 delivers identical clamping behavior regardless of surge polarity.
