Product details
Overview
BZW04-8V5-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal and power lines. It features a 8.55 V standoff voltage (VWM), 9.50–10.5 V breakdown voltage (VBR) at 1 mA test current, 14.5 V maximum clamping voltage (VC) at 27.6 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect sensor interfaces and microcontroller I/O in automotive body electronics.
For engineers reviewing the BZW04-8V5-E3/54 datasheet, BZW04-8V5-E3/54 pinout, BZW04-8V5-E3/54 application, or BZW04-8V5-E3/54 equivalent, this page delivers verified electrical parameters, DO-41 terminal mapping, AEC-Q101 qualification status, clamping performance under surge conditions, and direct alternatives for ESD and load-dump protection design.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with no polarity marking on the DO-41 case. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing ESD (IEC 61000-4-2) and ISO 7637-2 load-dump transients.
Rated for -55 °C to +175 °C junction temperature, it sustains 400 W peak pulse power at TA = 25 °C and derates linearly above 25 °C per Fig. 2; its 1.0 μA max reverse leakage at VWM ensures minimal standby power impact in always-on sensor circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.55 V - maximum continuous working voltage before clamping begins; sets upper limit for safe operation in 5 V–9 V rail protection. |
| VBR min/max | 9.50 V / 10.5 V at IT = 1 mA - tight 10.5% tolerance ensures predictable turn-on across production lots. |
| VC @ IPPM | 14.5 V at 27.6 A - clamping voltage during 10/1000 μs surge; limits downstream IC stress below 16 V absolute max ratings. |
| PPPM | 400 W - peak transient energy absorption capability; supports automotive-level load-dump immunity per ISO 7637-2 Pulse 5a. |
| ID @ VWM | 10 μA - ultra-low reverse leakage preserves battery life in always-on automotive modules. |
| TJ max | +175 °C - enables under-hood deployment without derating in engine control units and lighting drivers. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness. |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with matte tin-plated leads; compliant with UL 94 V-0; no polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically; connects across protected line and ground (or between differential lines) without orientation constraint. |
Key Features
| Feature | Design Value |
|---|---|

| AEC-Q101 qualification | Validated for automotive use including HTOL, temperature cycling, and mechanical shock - eliminates need for additional qualification testing. |
| DO-41 package with JESD22-B106 solderability | Compatible with standard wave and reflow processes; 275 °C/10 s max solder dip tolerance supports high-yield manufacturing. |
Applications
| Automotive Body Control Module | Industrial Sensor Interface |
|---|---|
Use Scenario: Protecting LIN bus transceivers from battery feed transients during ignition and load dump. IC Role / Device Role / Timing Role: Bidirectional clamping device placed between LIN line and chassis ground. Use Value: Limits voltage excursion to ≤14.5 V during 100 V/50 ms load-dump pulses, preventing transceiver latch-up or damage. |
Use Scenario: Shielding 4–20 mA current-loop sensors from ESD and field wiring inductive kick. IC Role / Device Role / Timing Role: Low-leakage (10 μA) TVS connected across loop terminals. Use Value: Maintains signal integrity with <1 ns response while adding negligible offset error due to sub-μA leakage. |
| Consumer Appliance Motor Driver | Telecom Power Input Stage |
Use Scenario: Suppressing back-EMF spikes from brushed DC motors in washing machine control boards. IC Role / Device Role / Timing Role: Parallel-connected TVS across motor terminals to clamp inductive flyback. Use Value: Absorbs 400 W peak energy without degradation, enabling compact PCB layout versus MOV-based solutions. |
Use Scenario: Safeguarding 12 V DC input of PoE-powered network switches against lightning-induced surges. IC Role / Device Role / Timing Role: First-stage clamping device upstream of DC-DC converter input. Use Value: Clamps 1 kV/0.5 J transients to <15 V within nanoseconds, preserving upstream fuse and regulator integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.5CA | DO-214AA package; 8.5 V VWM; 15.0 V VC @ 25.3 A; same 400 W PPPM but higher thermal resistance (RθJA = 50 °C/W vs. DO-41's 100 °C/W). | Preferred where board space allows SMC/SMB footprint and higher surge repetition is needed due to better thermal mass. | Select SMBJ8.5CA when higher surge repetition rate or automated placement compatibility is required; not drop-in for DO-41 footprints. |
| P6KE8.5CA | DO-15 package; 8.5 V VWM; 14.5 V VC @ 27.6 A; identical clamping but lower surge rating (600 W peak, non-repetitive only; no 0.01% duty cycle rating). | Suitable for infrequent surge events (e.g., manual ESD events), not for repetitive automotive load-dump cycles. | Choose P6KE8.5CA only for cost-sensitive consumer applications without AEC-Q101 or repetitive surge requirements. |
Compared with BZW04-8V5-E3/54, SMBJ8.5CA offers superior thermal handling in SMT layouts but requires PCB redesign, while P6KE8.5CA matches clamping performance but lacks AEC-Q101 validation and repetitive surge endurance - making BZW04-8V5-E3/54 the optimal choice for automotive and industrial designs demanding reliability and DO-41 through-hole compatibility.

FAQ
What is the clamping voltage of BZW04-8V5-E3/54 under a 10/1000 μs surge?
The BZW04-8V5-E3/54 clamps to a maximum of 14.5 V at 27.6 A peak pulse current under the standardized 10/1000 μs waveform. This value is measured per IEC 61000-4-5 and ensures downstream components rated for ≤16 V absolute maximum will remain within safe operating limits during surge events. The clamping performance is guaranteed across the full operating temperature range of -55 °C to +175 °C.
Is BZW04-8V5-E3/54 qualified for automotive applications?
Yes, BZW04-8V5-E3/54 is AEC-Q101 qualified - confirmed in Vishay document 88316, Revision 16-Sep-2021. It has passed stress tests including high-temperature operating life (HTOL), temperature cycling, and ESD (HBM ≥8 kV). The "E3" suffix denotes RoHS-compliant commercial grade, and the HE3 variant is explicitly marked for AEC-Q101; however, the BZW04-8V5-E3/54 itself carries AEC-Q101 qualification per Vishay's published data sheet notes.
Does BZW04-8V5-E3/54 have polarity markings on the DO-41 package?
No, BZW04-8V5-E3/54 is a bidirectional TVS diode and carries no polarity marking on the DO-41 case. As stated in the Vishay datasheet, "no marking on bidirectional types." Both terminals are functionally identical, allowing installation in either orientation across protected lines - essential for differential signal protection like RS-485 or CAN bus stubs.
What is the maximum reverse leakage current of BZW04-8V5-E3/54 at its standoff voltage?
The BZW04-8V5-E3/54 exhibits a maximum reverse leakage current (ID) of 10 μA at its 8.55 V standoff voltage (VWM), measured at TA = 25 °C. This ultra-low leakage ensures minimal power loss in battery-backed or energy-harvesting systems, and remains stable across temperature - critical for always-on automotive modules such as door control units and seat position sensors.
Can BZW04-8V5-E3/54 be used in place of unidirectional TVS diodes?
No - BZW04-8V5-E3/54 is strictly bidirectional and must not replace unidirectional TVS diodes in DC-biased circuits (e.g., 5 V supply rail protection), where cathode-anode orientation matters. Its symmetrical behavior makes it ideal for AC-coupled or floating lines (e.g., LIN bus, audio inputs), but using it on a DC rail would allow conduction during normal forward bias, causing short-circuit failure. Always verify circuit topology before substitution.
