Product details
Overview
BZW04-5V8BHE3/54 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 5.8 V standoff voltage (VWM), 6.45–7.14 V breakdown voltage (VBR) at 10 mA, 10.5 V clamping voltage (VC) at 38 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial control systems.
For engineers reviewing the BZW04-5V8BHE3/54 datasheet, BZW04-5V8BHE3/54 pinout, BZW04-5V8BHE3/54 application, or BZW04-5V8BHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, DO-41 mechanical compatibility, low leakage (<1000 μA at VWM), and thermal stability up to +175 °C junction temperature.
Technical Context
This device operates as a voltage-clamping protection element in both polarities, leveraging a glass-passivated silicon junction to achieve fast response (<1 ns) and low incremental surge resistance. Its bidirectional symmetry ensures identical electrical behavior across positive and negative transients, eliminating polarity concerns during PCB layout.
The BZW04-5V8BHE3/54 complies with AEC-Q101 for automotive-grade reliability and supports repetitive surge events at 0.01 % duty cycle. It is rated for 1.5 W steady-state power dissipation on an infinite heatsink at TL = 75 °C and withstands 8.3 ms half-sine forward surge currents up to 40 A in unidirectional variants - though this specific part is bidirectional and thus excludes IFSM rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.8 V - maximum continuous reverse working voltage before clamping begins; defines safe operating margin for protected circuitry. |
| VBR (min/max) | 6.45 V / 7.14 V at 10 mA - tight breakdown tolerance ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 10.5 V at 38 A - clamping voltage limits transient energy delivered to downstream components during 10/1000 μs surge. |
| PPPM | 400 W - peak pulse power handling capacity with standard 10/1000 μs waveform; enables robust ESD and load-dump protection. |
| ID @ VWM | 1000 μA - low reverse leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max. | +175 °C - extended junction temperature range supports under-hood automotive and industrial environments. |
| Package | DO-41 (DO-204AL) - industry-standard axial leaded package with UL 94 V-0 molded epoxy and matte tin-plated leads. |
Pinout & Package

| Consumer Power Adapter Interface | Telecom Line Card Surge Protection |
Use Scenario: Safeguarding USB-C or barrel-jack input stages of wall adapters against ESD and accidental AC mains contact. IC Role / Device Role / Timing Role: Primary-level transient suppressor located between input connector and primary-side controller IC or bridge rectifier. Use Value: Absorbs >15 kV contact ESD (IEC 61000-4-2) and limits let-through voltage to <20 V, protecting secondary-side regulation feedback paths. |
Use Scenario: Front-end protection of Ethernet PHY or DSL line drivers connected to outside plant wiring susceptible to lightning-induced surges. IC Role / Device Role / Timing Role: First-stage clamping device on differential pair or single-ended line interface, coordinated with GDT or MOV secondary protection. Use Value: Limits induced common-mode transients to <15 V peak, preserving signal integrity and preventing damage to 3.3 V or 1.8 V PHY transceivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-E3/52 | Unidirectional; 5.0 V VWM; SMB surface-mount package (vs. DO-41 through-hole); lower VC (9.2 V @ 43.3 A). | Requires polarity-aware placement; better suited for space-constrained PCBs with automated assembly. | Select when board real estate is limited and unidirectional protection suffices with tighter clamping. |
| P6KE6.8A | Unidirectional; 6.8 V VWM; DO-15 package (larger than DO-41); same 400 W PPPM but higher VC (10.5 V @ 38.2 A). | Compatible with legacy DO-15 footprints; slightly higher standoff voltage reduces false triggering in noisy 5 V rails. | Choose for drop-in replacement in existing DO-15 designs where AEC-Q101 is not required. |
Compared with BZW04-5V8BHE3/54, SMBJ5.0A-E3/52 offers superior mounting density and lower clamping but lacks bidirectionality and automotive qualification; P6KE6.8A provides mechanical interchangeability with DO-15 layouts but omits AEC-Q101 validation and has marginally higher leakage.

FAQ
What is the polarity configuration of BZW04-5V8BHE3/54?
BZW04-5V8BHE3/54 is a bidirectional TVS diode with symmetrical terminals - neither lead is marked as anode or cathode. This allows it to suppress transients of either polarity without regard to orientation during PCB assembly, simplifying layout and eliminating polarity-related assembly errors in AC-coupled or floating signal paths.
Is BZW04-5V8BHE3/54 qualified for automotive applications?
Yes, BZW04-5V8BHE3/54 carries the HE3 suffix, indicating full AEC-Q101 qualification. It has undergone stress testing for temperature cycling, humidity bias, mechanical shock, and ESD per automotive standards, making it suitable for engine control, body electronics, and ADAS sensor protection in passenger vehicles and commercial transport.
What does the "B" suffix mean in BZW04-5V8BHE3/54?
The "B" suffix in BZW04-5V8BHE3/54 explicitly denotes bidirectional functionality. Unlike unidirectional variants (e.g., BZW04-5V8HE3/54), this part provides identical clamping behavior for both positive- and negative-going transients, confirmed by matching VBR min/max and VC values in both directions per the Vishay datasheet.
How does BZW04-5V8BHE3/54 compare to standard Zener diodes in surge protection?
BZW04-5V8BHE3/54 is engineered specifically for transient suppression - it delivers 400 W peak pulse power with sub-nanosecond response, whereas general-purpose Zeners lack controlled surge ratings and degrade rapidly under repetitive transients. Its glass-passivated junction and optimized doping ensure stable clamping over lifetime, unlike Zeners which exhibit parameter drift after repeated surges.
What is the maximum allowable soldering temperature for BZW04-5V8BHE3/54?
BZW04-5V8BHE3/54 supports solder dip at 275 °C maximum for 10 seconds per JESD22-B106, and reflow profiles must comply with JEDEC J-STD-020. Lead finish is matte tin, ensuring compatibility with Pb-free and SnPb processes; exceeding these limits risks delamination of the epoxy mold or junction degradation.
