Product details
Overview
BZW04P9V4B-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 BZW04P9V4B-E3/54 datasheet, BZW04P9V4B-E3/54 pinout, BZW04P9V4B-E3/54 application, or BZW04P9V4B-E3/54 equivalent, key selection criteria include its bi-directional symmetry, AEC-Q101 qualification, DO-204AL (DO-41) package compatibility, low 0.075 %/°C VBR temperature coefficient, and 1.0 mA test current for precise breakdown validation.
Technical Context
This bi-directional TVS operates symmetrically in both polarities, with identical electrical characteristics forward and reverse - enabling single-device protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable leakage performance and fast response (<1 ns) to ESD and surge transients.
The device is rated for 400 W peak pulse power under 10/1000 μs waveform at TA = 25 °C, derated 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 rails. |
| VBR min/max | 10.5 V / 12.1 V at IT = 1.0 mA - tight breakdown window ensures predictable turn-on across production lots. |
| VC @ IPPM | 15.6 V at 25.7 A - clamping voltage limits downstream IC stress during 400 W transient events. |
| ID @ VWM | 5.0 µA - ultra-low reverse leakage preserves signal integrity in high-impedance sensor circuits. |
| PPPM | 400 W - peak surge handling capability per 10/1000 μs standard waveform, suitable for IEC 61000-4-5 Level 3. |
| TJ max | +175 °C - extended thermal rating enables under-hood automotive use and high-ambient industrial environments. |
| AEC-Q101 | Qualified - certified for automotive electronics per stress test requirements including HTGB, H3TRB, and TCT. |
Pinout & Package
Package: DO-204AL (DO-41), axial-leaded, epoxy-molded case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bi-directional) | Transient conduction path | No polarity marking; terminals are functionally identical - conducts surge current equally in either direction. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable, low-leakage operation and long-term reliability under thermal cycling and humidity exposure. |
| 400 W peak pulse power (10/1000 μs) | Supports robust protection against lightning-induced surges and inductive switching transients in industrial controls. |
| AEC-Q101 qualified | Validated for automotive applications including body electronics, infotainment, and ADAS sensor interfaces. |
| Bi-directional symmetry | Eliminates need for polarity-aware layout; simplifies PCB design for differential or AC-coupled signal lines. |
| Low 0.075 %/°C VBR tempco | Minimizes drift in clamping threshold across –55 °C to +175 °C, critical for wide-temperature automotive deployment. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed directly at connector entry point to shunt transients before reaching protected ICs. Use Value: Prevents latch-up or permanent damage to 5 V or 12 V sensor front-ends while maintaining signal fidelity via low 5.0 µA leakage. |
Use Scenario: Safeguarding digital input modules in programmable logic controllers exposed to relay coil flyback and field wiring surges. IC Role / Device Role / Timing Role: Primary surge suppression element on 24 V DC input channels, coordinated with upstream fusing. Use Value: Withstands repetitive 400 W transients without degradation, extending system uptime in factory automation environments. |
| Telecom Line Interface | Consumer Audio Signal Path |
Use Scenario: Shielding RS-485/RS-422 transceivers in base station backhaul equipment from induced lightning surges on long cable runs. IC Role / Device Role / Timing Role: First-line transient suppressor on differential pair, placed before common-mode choke and receiver IC. Use Value: Symmetrical 15.6 V clamping ensures balanced protection without skewing differential voltage margins. |
Use Scenario: Guarding line-in/line-out jacks in AV receivers and smart speakers against ESD during user connection/disconnection. IC Role / Device Role / Timing Role: Low-capacitance TVS (typ. <50 pF) integrated near jack to absorb human-body-model (HBM) discharges. Use Value: Sub-1 ns response time prevents ESD energy from propagating into audio codec or amplifier circuitry. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0A | Uni-directional; 9.0 V VWM; 14.4 V VC @ 27.8 A; same DO-214AA package but different footprint. | Requires polarity-aware placement; unsuitable for AC or floating lines without external biasing. | Select when unidirectional protection suffices and board space allows SMB package; verify layout clearance vs. DO-41. |
| P6KE9.1A | Uni-directional; 9.1 V VWM; 13.4 V VC @ 29.8 A; larger DO-15 package; lower PPPM (600 W) but higher IFSM (100 A). | Higher surge margin but incompatible pin spacing; not AEC-Q101 qualified. | Prefer for non-automotive industrial designs needing higher single-pulse tolerance and legacy DO-15 compatibility. |
Compared with BZW04P9V4B-E3/54, SMBJ9.0A offers tighter clamping but lacks bi-directional flexibility, while P6KE9.1A delivers higher surge capacity in a non-automotive-qualified, physically larger package - making BZW04P9V4B-E3/54 the optimal choice for space-constrained, AEC-Q101–required bi-directional protection.

FAQ
What is the clamping voltage of BZW04P9V4B-E3/54 and how is it measured?
The BZW04P9V4B-E3/54 has a maximum clamping voltage (VC) of 15.6 V, measured at a peak pulse current (IPPM) of 25.7 A using the standardized 10/1000 μs double-exponential waveform. This value represents the upper voltage limit imposed on protected circuitry during a worst-case transient event, ensuring downstream ICs remain within safe operating voltage ranges.
Is BZW04P9V4B-E3/54 suitable for automotive applications?
Yes, BZW04P9V4B-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its –55 °C to +175 °C operating junction temperature range, glass-passivated junction, and rigorous stress testing (including HTGB and TCT) validate its suitability for engine control units, body electronics, and ADAS sensor interfaces.
Does BZW04P9V4B-E3/54 have polarity markings?
No, BZW04P9V4B-E3/54 is a bi-directional TVS diode and carries no polarity marking on the DO-41 package. Both terminals are functionally identical, allowing installation without orientation concern - a key advantage for protecting AC-coupled or floating signal paths.
What is the maximum reverse leakage current for BZW04P9V4B-E3/54 at its stand-off voltage?
At its 9.4 V stand-off voltage (VWM), the BZW04P9V4B-E3/54 exhibits a maximum reverse leakage current (ID) of 5.0 µA at TA = 25 °C. This ultra-low leakage preserves signal integrity in high-impedance circuits such as precision sensor front-ends and analog monitoring paths.
How does the temperature coefficient affect BZW04P9V4B-E3/54's breakdown voltage?
The BZW04P9V4B-E3/54 has a maximum temperature coefficient of 0.075 %/°C for its breakdown voltage (VBR). This means VBR increases by up to 0.075 % per degree Celsius rise in junction temperature - a tightly controlled drift that ensures consistent clamping behavior across its full –55 °C to +175 °C operating range.
