Product details
Overview
BZW04P9V4-E3/54 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 BZW04P9V4-E3/54 datasheet, BZW04P9V4-E3/54 pinout, BZW04P9V4-E3/54 application, or BZW04P9V4-E3/54 equivalent, key selection criteria include its DO-204AL (DO-41) axial package, AEC-Q101 qualification, bi-directional symmetry, low 0.075 %/°C VBR temperature coefficient, and compliance with IEC 61000-4-2/4-4/4-5 surge immunity standards.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with identical electrical characteristics forward and reverse - enabling single-device protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance under repetitive transients.
The device delivers 400 W peak pulse power handling per 10/1000 μs waveform at TA = 25 °C, derating linearly above 25 °C per Fig. 2, and supports continuous power dissipation of 1.5 W on an infinite heatsink at TL = 75 °C. Junction temperature range spans −55 °C to +175 °C, validated per AEC-Q101 stress testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.4 V - maximum continuous working voltage before clamping begins; defines safe operating margin for 9 V nominal supply rails. |
| VC @ IPPM | 15.6 V - clamped voltage at 25.7 A peak pulse current; limits downstream IC stress during 10/1000 μs surges. |
| PPPM | 400 W - peak pulse power rating per 10/1000 μs waveform; meets IEC 61000-4-5 Level 4 (4 kV) surge requirements. |
| ID @ VWM | 5.0 μA - reverse leakage at 9.4 V; negligible bias current impact on high-impedance sensor or communication lines. |
| VBR min/max | 10.5 V / 12.1 V - breakdown voltage range at 1.0 mA test current; ensures consistent turn-on across production lots. |
| TJ max | +175 °C - maximum junction temperature; supports under-hood automotive and industrial environments. |
| Package | DO-204AL (DO-41) - axial-leaded, UL 94 V-0 molded epoxy case; compatible with wave soldering (275 °C, 10 s). |

|---|---|
Use Scenario: Protecting CAN/LIN bus nodes and analog sensor outputs (e.g., pressure, temperature) from load dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed directly at connector entry point, shunting surge energy before it reaches MCU or analog front-end. Use Value: Limits transient voltage to ≤15.6 V during 25.7 A events, preserving signal integrity and preventing latch-up in 5 V/3.3 V logic interfaces. |
Use Scenario: Safeguarding half-duplex RS-485 transceivers (e.g., SN65HVD230) against ESD and lightning-induced surges on factory floor cabling. IC Role / Device Role / Timing Role: Bi-directional TVS placed across differential pair (A/B) and ground, providing symmetrical clamping without affecting DC bias. Use Value: Maintains <5 μA leakage at 9.4 V, avoiding signal distortion; clamps 4 kV IEC 61000-4-5 surges within 1 ns response time. |
| Telecom Line Card Protection | Consumer Appliance Motor Control |
Use Scenario: Shielding DSL/VDSL line drivers and POTS interface circuits from induced surges on outside plant wiring. IC Role / Device Role / Timing Role: First-stage protection device mounted at line entry, coordinated with GDT or MOV secondary stages. Use Value: 400 W PPPM rating handles repetitive surges per GR-1089-CORE; DO-41 footprint allows dense PCB placement near connectors. |
Use Scenario: Suppressing commutation spikes from brushed DC motors in washing machines, HVAC blowers, and power tools. IC Role / Device Role / Timing Role: Parallel-mounted across motor terminals to clamp inductive kickback before reaching driver IC or microcontroller GPIO. Use Value: Withstands 40 A non-repetitive forward surge (IFSM); 175 °C TJ rating tolerates enclosure heat buildup during sustained operation. |
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 (SMB) package; 9.0 V VWM; 14.4 V VC @ 27.8 A; same 400 W PPPM rating. | Surface-mount alternative requiring PCB re-layout; higher thermal resistance than axial DO-41 in free-air conditions. | Select when automated SMT assembly is required and board space is constrained. |
| P6KE9.1A | DO-15 package; 9.1 V VWM; 14.5 V VC @ 27.5 A; 600 W PPPM (10/1000 μs); unidirectional only. | Lacks bi-directional symmetry; requires external series resistor or dual-device configuration for AC signals. | Choose only for DC rail protection where polarity is fixed and higher pulse power margin is needed. |
Compared with SMBJ9.0CA and P6KE9.1A, BZW04P9V4-E3/54 offers verified AEC-Q101 qualification, axial through-hole mounting for mechanical robustness in high-vibration environments, and native bi-directional operation - making it optimal for automotive and industrial field-deployed systems where reliability and ease of manual repair matter.

FAQ
What is the clamping voltage of BZW04P9V4-E3/54 under standard surge conditions?
The BZW04P9V4-E3/54 has a maximum clamping voltage (VC) of 15.6 V when subjected to its rated peak pulse current of 25.7 A using the 10/1000 μs waveform. This value is measured per IEC 61000-4-5 test methodology and ensures downstream circuitry remains below destructive voltage thresholds during transient events. The BZW04P9V4-E3/54 maintains this clamping performance across its full operating temperature range.
Is BZW04P9V4-E3/54 suitable for automotive applications?
Yes, BZW04P9V4-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its DO-204AL package, −55 °C to +175 °C junction temperature range, and robust 400 W surge capability make it appropriate for engine control units, body control modules, and ADAS sensor interfaces. The BZW04P9V4-E3/54 meets stress test requirements for humidity, temperature cycling, and mechanical shock defined in AEC-Q101.
Does BZW04P9V4-E3/54 have polarity markings?
No, BZW04P9V4-E3/54 is a bi-directional TVS diode and carries no polarity marking - there is no cathode band or other visual indicator. Its symmetrical construction means either lead can connect to any side of the protected line. This simplifies assembly and eliminates orientation errors during manual or automated insertion - a key advantage of the BZW04P9V4-E3/54 in high-reliability designs.
What is the maximum steady-state power dissipation of BZW04P9V4-E3/54?
The BZW04P9V4-E3/54 has a maximum steady-state power dissipation (PD) of 1.5 W when mounted on an infinite heatsink at a lead temperature (TL) of 75 °C. Derating follows the curve in Figure 5 of the datasheet, reducing allowable power linearly as TL increases beyond 75 °C. This PD rating applies only to continuous DC or low-frequency operation - not to transient pulse conditions where PPPM governs.
How does the temperature coefficient affect BZW04P9V4-E3/54 performance?
The BZW04P9V4-E3/54 has a maximum temperature coefficient of breakdown voltage (VBR) of 0.075 %/°C, meaning VBR shifts by ≤0.075 % per degree Celsius change in junction temperature. This low drift ensures predictable clamping onset across its full −55 °C to +175 °C operating range - critical for maintaining protection margins in under-hood or industrial enclosures where ambient temperatures vary widely. The BZW04P9V4-E3/54 remains stable without recalibration or compensation.
