Product details
Overview
BZW04-7V0BHE3/54 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 a 7.02 V standoff voltage (VWM), 7.79–8.61 V breakdown voltage (VBR) at 10 mA, 33.0 A peak pulse current (IPPM), and 12.1 V clamping voltage (VC) under 10/1000 μs surge - used to protect MOSFETs, sensor interfaces, and microcontroller I/O in automotive and industrial control systems.
For engineers reviewing the BZW04-7V0BHE3/54 datasheet, BZW04-7V0BHE3/54 pinout, BZW04-7V0BHE3/54 application, or BZW04-7V0BHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 400 W peak pulse power rating, low leakage (<200 μA at VWM), and DO-41 mechanical compatibility with legacy through-hole PCB layouts.
Technical Context
This device operates as a bidirectional avalanche diode, symmetrically clamping both positive and negative transients without polarity dependence. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance, enabling consistent clamping performance across repetitive 10/1000 μs pulses at 0.01% duty cycle.
The BZW04-7V0BHE3/54 is rated for 175 °C maximum junction temperature and supports soldering up to 275 °C for 10 s per JESD22-B106. Its 0.065 %/°C VBR temperature coefficient indicates moderate drift over temperature, suitable for ambient ranges from –55 °C to +175 °C in engine bay or industrial enclosure environments.
Key Specifications

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting analog voltage outputs of pressure or temperature sensors connected to vehicle ECUs against load dump and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at sensor connector interface to shunt transients before reaching ADC input stage. Use Value: Prevents latch-up or damage to 12-bit SAR ADCs by limiting transient voltage to ≤12.1 V while maintaining <200 μA leakage at 7.02 V nominal supply. | Use Scenario: Safeguarding digital input channels of programmable logic controllers exposed to relay coil flyback and motor drive noise in factory automation. IC Role / Device Role / Timing Role: Parallel-connected TVS on 24 V DC input lines to clamp induced spikes from inductive switching within <1 ns response time. Use Value: Enables reliable operation at 85 °C ambient with 175 °C junction rating, sustaining 400 W surges without derating in DIN-rail mounted enclosures. |
| Consumer Power Adapter Interface | MOSFET Gate Driver Protection |
Use Scenario: Shielding USB-C PD controller communication lines (CC1/CC2) from ESD and cable-induced transients during hot-plug events. IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS placed adjacent to connector to suppress ±8 kV contact ESD per IEC 61000-4-2. Use Value: Clamps to 12.1 V before controller IC reaches absolute maximum ratings, with no polarity marking simplifying layout and assembly. | Use Scenario: Protecting high-side N-channel MOSFET gate drivers in half-bridge motor controllers from shoot-through-inducing voltage spikes. IC Role / Device Role / Timing Role: Clamp placed between gate and source to limit dV/dt-induced false turn-on during switching transitions. Use Value: Maintains gate oxide integrity with 7.02 V standoff, preventing unintended conduction while surviving 33.0 A surge currents from parasitic inductance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | Unidirectional; SMA package; 7.0 V VWM; 100 W PPPM | Requires external polarity management; lower surge rating limits use in high-energy automotive transients | Select when space-constrained SMT layout is mandatory and peak surge energy is ≤100 W |
| P6KE7.0A | Unidirectional; DO-15 package; 7.0 V VWM; 600 W PPPM | Larger DO-15 footprint; higher clamping voltage (12.6 V) increases downstream stress | Choose for legacy through-hole designs needing higher pulse power where 0.5 V clamping margin is acceptable |
Compared with BZW04-7V0BHE3/54, SMBJ7.0A offers surface-mount compatibility but sacrifices 75% peak power handling and bidirectionality, while P6KE7.0A delivers greater surge capacity in a larger axial package but with reduced clamping precision and unidirectional constraint.

FAQ
What is the clamping voltage of BZW04-7V0BHE3/54 under a 10/1000 μs surge?
The BZW04-7V0BHE3/54 has a maximum clamping voltage (VC) of 12.1 V at 33.0 A peak pulse current under the standardized 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88316 and represents the upper bound of voltage seen by protected circuitry during worst-case transient events, ensuring downstream components remain within safe operating limits.
Is BZW04-7V0BHE3/54 suitable for automotive applications?
Yes, BZW04-7V0BHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass-passivated junction, UL 94 V-0 epoxy, and validation across temperature cycling, high-temperature reverse bias, and ESD stress - making it appropriate for engine control units, body electronics, and ADAS sensor interfaces where reliability under thermal and electrical stress is mandatory.
Does BZW04-7V0BHE3/54 have polarity markings?
No, BZW04-7V0BHE3/54 is a bidirectional TVS diode and carries no polarity marking on the DO-41 package. The device functions identically regardless of lead orientation, simplifying PCB layout and assembly - unlike unidirectional variants (e.g., BZW04-7V0HE3/54) which feature a cathode band.
What is the maximum junction temperature rating for BZW04-7V0BHE3/54?
The BZW04-7V0BHE3/54 has a maximum junction temperature (TJ max) of +175 °C, as specified in the "Maximum Ratings and Thermal Characteristics" table of Vishay document 88316. This allows operation in high-ambient environments such as under-hood automotive locations or sealed industrial enclosures without thermal derating below full 400 W pulse capability at TA = 25 °C.
How does the 7.02 V standoff voltage (VWM) of BZW04-7V0BHE3/54 relate to system supply rails?
The 7.02 V VWM of BZW04-7V0BHE3/54 is selected to safely coexist with nominal 5 V or 6.5 V logic and sensor supply rails while providing margin above normal operating voltage. It ensures the device remains non-conductive during steady-state conditions yet triggers rapidly during overvoltage events exceeding ~7.8 V, making it ideal for protecting 5 V microcontroller I/O, CAN transceivers, and analog front-ends without leakage-induced errors.
