Product details
Overview
BZW04P8V5B-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 8.55 V stand-off voltage (VWM), 9.50–11.0 V breakdown voltage (VBR) at 1 mA, 14.5 V clamping voltage (VC) at 27.6 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the BZW04P8V5B-E3/54 datasheet, BZW04P8V5B-E3/54 pinout, BZW04P8V5B-E3/54 application, or BZW04P8V5B-E3/54 equivalent, key selection criteria include its bi-directional capability, AEC-Q101 qualification, DO-204AL (DO-41) through-hole package, low 0.07 %/°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, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable leakage performance and fast response (<1 ns) to ESD and lightning-induced transients.
The device delivers 400 W peak pulse power handling per 10/1000 μs waveform at TA = 25 °C, with thermal derating above 25 °C per Fig. 2 and junction temperature limits up to 175 °C. It exhibits low incremental surge resistance and excellent clamping ratio (VC/VBR ≈ 1.45), critical for safeguarding sensitive downstream ICs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.55 V - maximum continuous reverse operating voltage before conduction begins; defines safe working margin for 5 V–9 V nominal systems. |
| VBR (min/max) | 9.50 V / 11.0 V at IT = 1 mA - precise breakdown threshold ensuring reliable triggering during overvoltage events. |
| VC @ IPPM | 14.5 V at 27.6 A - clamped voltage seen by protected circuit during worst-case 400 W transient; limits stress on downstream components. |
| PPPM | 400 W - peak transient energy absorption capacity with 10/1000 μs waveform, supporting IEC 61000-4-5 Level 3 (1 kV line-to-line). |
| ID @ VWM | 10 μA - ultra-low reverse leakage at stand-off voltage, minimizing standby power loss and signal distortion. |
| TJ max. | 175 °C - extended junction temperature rating enables use in under-hood automotive and high-ambient industrial environments. |
| Temp. Coeff. | 0.07 %/°C - low VBR drift over temperature ensures consistent protection threshold across -55 °C to +175 °C range. |
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 |

| 400 W peak pulse power | Withstands repetitive 10/1000 μs surges at 0.01 % duty cycle - suitable for industrial motor drive I/O and telecom line protection. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes voltage overshoot during clamping, reducing risk of latch-up or damage to 3.3 V/5 V logic and analog front-ends. |
| RoHS-compliant, matte tin leads | Meets JESD201 Class 1A whisker resistance; supports lead-free reflow and wave soldering processes. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed directly at connector entry point to shunt transients before reaching interface ICs. Use Value: Maintains signal integrity under ±200 V/50 ms load dump events while adding <0.5 pF parasitic capacitance - no data rate degradation. |
Use Scenario: Shielding digital input modules from inductive kickback in factory automation systems with solenoids and relays. IC Role / Device Role / Timing Role: Primary overvoltage suppression element on 24 V DC input channels, coordinated with series impedance and filtering. Use Value: Limits transient voltage to ≤14.5 V during 400 W surges, preventing false triggering and microcontroller reset events. |
| Consumer Audio Line Protection | Telecom DSL/ADSL Interface |
Use Scenario: Safeguarding line-level audio inputs/outputs in AV receivers and smart speakers against ESD and cable discharge events. IC Role / Device Role / Timing Role: Bi-directional TVS placed across unbalanced RCA or 3.5 mm jack pins to absorb ±15 kV contact ESD (IEC 61000-4-2). Use Value: Sub-1 ns response time clamps ESD pulses before audio codec inputs saturate, preserving dynamic range and THD+N performance. |
Use Scenario: Protecting ADSL line drivers and SLIC interfaces from lightning-induced surges on telephone line pairs. IC Role / Device Role / Timing Role: First-stage transient suppressor on tip/ring lines, upstream of gas discharge tube (GDT) and secondary filtering. Use Value: Handles 10/1000 μs surges up to 400 W (IEC 61000-4-5), enabling compact design without external heat sinking. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.5CA | Same DO-214AA package; higher 600 W PPPM but larger 15.0 V VC at 38.9 A - less tight clamping than BZW04P8V5B-E3/54. | Preferred where board space is constrained and higher surge margin is needed, but less optimal for low-voltage rail protection. | Select SMBJ8.5CA only if 15.0 V clamping is acceptable for protected IC's absolute maximum rating. |
| P6KE8.5CA | DO-15 package; same 8.5 V VWM and 14.5 V VC, but lower 600 W rating derated to 400 W at elevated ambient - identical clamping but larger footprint. | Used in legacy industrial designs with existing DO-15 footprints; not AEC-Q101 qualified. | Choose P6KE8.5CA only for non-automotive applications where DO-15 compatibility is mandatory and AEC-Q101 is not required. |
Compared with SMBJ8.5CA and P6KE8.5CA, BZW04P8V5B-E3/54 offers AEC-Q101 qualification, tighter VBR tolerance (±7.9 % vs ±10 %), and DO-41 through-hole mounting ideal for high-reliability wired connections - making it the preferred choice for automotive and ruggedized industrial deployments.
