Product details
Overview
BZW04-8V5HE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features 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 MOSFET gates, sensor interfaces, and microcontroller I/O in automotive ECUs and industrial PLCs.
For engineers reviewing the BZW04-8V5HE3/54 datasheet, BZW04-8V5HE3/54 pinout, BZW04-8V5HE3/54 application, or BZW04-8V5HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, bidirectional polarity, low 0.075 %/°C VBR temperature coefficient, and 10 μA max reverse leakage at VWM - critical for low-power, high-reliability transient suppression in automotive and industrial environments.
Technical Context
This device operates as a voltage-clamping surge protector with symmetrical bidirectional conduction, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance, while the DO-41 package supports manual or automated through-hole assembly with JESD22-B106-compliant soldering.
The BZW04-8V5HE3/54 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 maintains clamping performance across -55 °C to +175 °C operating junction temperature range - making it suitable for under-hood automotive and high-temperature industrial deployments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.55 V - maximum continuous reverse working voltage before clamping initiates; sets safe operating margin for 9 V nominal supply rails. |
| VBR min/max | 9.50 V / 10.5 V at 1 mA - defines precise breakdown threshold window for predictable turn-on during overvoltage events. |
| VC @ IPPM | 14.5 V at 27.6 A - clamping voltage under full 400 W surge; limits downstream IC stress to safe levels during ESD or load dump. |
| PPPM | 400 W - peak pulse power capability with 10/1000 μs waveform; meets IEC 61000-4-5 Level 3 surge immunity requirements. |
| ID @ VWM | 10 μA max - ultra-low reverse leakage ensures minimal quiescent current impact on battery-powered sensor nodes. |
| TJ max | +175 °C - extended junction temperature rating enables use in engine control modules and motor drive inverters. |

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting analog output lines of pressure/temperature sensors in engine control units exposed to load dump and ISO 7637-2 transients. IC Role / Device Role / Timing Role: Bidirectional TVS clamps both positive and negative voltage spikes on 0–5 V sensor outputs to prevent ADC input damage. Use Value: Maintains signal integrity with <14.5 V clamping during 27.6 A surges, preserving sensor accuracy and ECU uptime. | Use Scenario: Shielding digital input channels of programmable logic controllers from inductive kickback when switching solenoids or relays. IC Role / Device Role / Timing Role: Fast-response TVS suppresses >100 ns transients before they reach FPGA or microcontroller GPIO pins. Use Value: Limits transient energy to <400 W with sub-nanosecond response, preventing latch-up or permanent I/O port failure. |
| Consumer Audio Interface Protection | Telecom Line Card Surge Suppression |
Use Scenario: Safeguarding line-in/line-out jacks of home theater receivers against ESD and cable-induced surges. IC Role / Device Role / Timing Role: Bidirectional clamping protects unbalanced audio paths where signal swings above and below ground. Use Value: Low 10 μA leakage avoids DC offset in analog audio stages; 8.55 V VWM matches typical 9 V rail headroom. | Use Scenario: Front-end protection of DSL or POTS line cards against lightning-induced surges on twisted-pair copper lines. IC Role / Device Role / Timing Role: Primary surge limiter in series with GDT or MOV-based hybrid protection circuits. Use Value: 14.5 V VC ensures downstream transceiver ICs (e.g., ADSL PHY) remain within absolute maximum ratings during 10/1000 μs surges. |
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 | Surface-mount SMB package; same 8.5 V VWM but 600 W PPPM rating; higher VC (13.6 V @ 32.1 A). | Preferred for space-constrained PCBs; requires rework for existing DO-41 footprints. | Select when board area is limited and higher surge margin is needed; not drop-in compatible due to SMT vs. through-hole packaging. |
| P6KE8.5CA | Legacy 600 W DO-15 package; identical VWM/VBR specs but larger footprint and lower thermal mass; 13.6 V VC @ 29.1 A. | Suitable for legacy designs with DO-15 land patterns; less optimized for high-frequency transient response. | Choose for cost-sensitive industrial replacements where DO-15 compatibility is mandatory; verify mechanical clearance and thermal derating. |
Compared with SMBJ8.5CA and P6KE8.5CA, the BZW04-8V5HE3/54 offers AEC-Q101 qualification and tighter VBR tolerance in a compact DO-41 package - making it optimal for new automotive and high-reliability industrial designs requiring validated automotive-grade robustness and through-hole manufacturability.

FAQ
What is the polarity configuration of the BZW04-8V5HE3/54?
The BZW04-8V5HE3/54 is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive and negative voltage transients. Unlike unidirectional variants, it has no cathode marking and functions identically regardless of terminal orientation - ideal for protecting AC-coupled or differential signal paths without polarity constraints.
Does the BZW04-8V5HE3/54 meet automotive qualification standards?
Yes, the BZW04-8V5HE3/54 carries the HE3 suffix, indicating full AEC-Q101 qualification. This includes rigorous testing for temperature cycling, highly accelerated life testing (HALT), and ESD robustness - confirming suitability for automotive powertrain, body electronics, and ADAS sensor interface applications.
What is the maximum clamping voltage of the BZW04-8V5HE3/54 under surge conditions?
The BZW04-8V5HE3/54 exhibits a maximum clamping voltage (VC) of 14.5 V when subjected to its rated peak pulse current of 27.6 A using the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and ensures downstream ICs remain within safe voltage limits during surge events.
How does the BZW04-8V5HE3/54 differ from the unidirectional BZW04-8V5E3/54?
The BZW04-8V5HE3/54 is bidirectional with no polarity marking and symmetrical VBR/VWM characteristics, whereas the unidirectional BZW04-8V5E3/54 has a cathode band and only clamps positive transients. Both share identical DO-41 packaging and AEC-Q101 qualification, but the bidirectional version is required for AC signal or differential bus protection.
What is the reverse leakage current specification for the BZW04-8V5HE3/54 at its standoff voltage?
At its 8.55 V standoff voltage (VWM), the BZW04-8V5HE3/54 specifies a maximum reverse leakage current (ID) of 10 μA at 25 °C. This ultra-low leakage preserves signal integrity and minimizes standby power loss in battery-operated sensor nodes and low-power industrial monitoring systems.
