Product details
Overview
BZW04-7V0HE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of signal and power lines. It features a 7.02 V stand-off voltage (VWM), 7.79–8.61 V breakdown voltage (VBR) at 10 mA, 12.1 V clamping voltage (VC) at 33.0 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the BZW04-7V0HE3/54 datasheet, BZW04-7V0HE3/54 pinout, BZW04-7V0HE3/54 application, or BZW04-7V0HE3/54 equivalent, this AEC-Q101 qualified TVS offers verified bidirectional surge suppression, low leakage (<200 μA at VWM), and stable temperature coefficient (0.065 %/°C), critical for ESD and load-switching transient mitigation in harsh environments.
Technical Context
This device operates as a voltage-clamped shunt protector: during transients exceeding VWM, it avalanches into low-impedance conduction to divert surge energy away from downstream circuitry. Its glass-passivated junction ensures stable VBR tolerance and repeatable clamping behavior across temperature.
Rated for 10/1000 μs waveform per IEC 61000-4-5, it delivers 33.0 A peak pulse current (IPPM) while maintaining ≤12.1 V clamping - enabling reliable protection of 5 V logic rails and analog sensor inputs without overstressing connected ICs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.02 V - maximum continuous reverse operating voltage before avalanche onset; defines safe working margin for 5 V systems. |
| VBR (min/max) | 7.79 V / 8.61 V at 10 mA - tight breakdown window ensures predictable turn-on and minimal variation across production lots. |
| VC @ IPPM | 12.1 V at 33.0 A - clamping voltage limits stress on protected ICs during 400 W surges, preserving signal integrity. |
| IPPM | 33.0 A - peak surge current handling capability under standardized 10/1000 μs waveform; sufficient for ISO 7637-2 Pulse 1/2a/2b. |
| PPPM | 400 W - peak pulse power rating confirms suitability for automotive and industrial transient standards including IEC 61000-4-4/5. |
| TJ max. | 175 °C - high junction temperature rating supports operation in under-hood and industrial control cabinet environments. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; no polarity marking for bidirectional configuration - both terminals are functionally identical and interchangeable in circuit layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Surge current path | Either terminal conducts during positive or negative transients - no orientation required during placement. |
| Lead 1 / Lead 2 | PCB interconnect interface | Matte tin-plated, J-STD-002 solderable leads; 0.028–0.034 inch diameter supports standard through-hole reflow or wave soldering. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures long-term VBR stability and low parameter drift over temperature and lifetime - critical for automotive field reliability. |
| 400 W peak pulse power (10/1000 μs) | Validated surge handling for repetitive transients up to 0.01 % duty cycle - supports continuous protection in motor drive feedback loops. |
| AEC-Q101 qualification | Confirms compliance with automotive stress tests including HTSL, TC, and AC/HTRB - enables use in ADAS sensor modules and body control units. |
| UL 94 V-0 molding compound | Self-extinguishing epoxy housing meets flammability safety requirements for industrial and transportation equipment enclosures. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ESD >15 kV), improving protection margin for precision analog front-ends. |
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 inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional shunt clamp placed directly at connector entry point to limit line voltage to ≤12.1 V during ISO 7637-2 Pulse 5a. Use Value: Prevents latch-up or permanent damage to 5 V rail-connected transceivers without adding series impedance or signal delay. |
Use Scenario: Safeguarding digital input channels of programmable logic controllers against 2 kV EFT bursts and 1 kV surge per IEC 61000-4-4/5. IC Role / Device Role / Timing Role: Primary transient suppressor on 24 V DC input lines, mounted upstream of optocoupler isolation stage. Use Value: Maintains functional safety integrity by clamping transients below the optocoupler's absolute maximum rating (typically 30 V). |
| Consumer Power Adapter Interface | Telecom Line Card Surge Protection |
Use Scenario: Shielding USB-C PD controller and voltage monitor ICs from surges induced by hot-plug events or shared ground noise in multi-port adapters. IC Role / Device Role / Timing Role: Secondary-level TVS on VBUS line after primary fuse and common-mode choke, responding within <1 ns. Use Value: Enables compliance with UL 62368-1 transient immunity requirements while preserving 5–20 V PD negotiation range. |
Use Scenario: Protecting Ethernet PHY and PoE controller pins on telecom line cards exposed to lightning-induced surges on RJ45 ports. IC Role / Device Role / Timing Role: First-stage shunt device on differential pairs, coordinated with GDT and series impedance for multi-level protection. Use Value: Limits coupled surge energy to <100 mJ per line pair, preventing PHY latch-up and maintaining IEEE 802.3af/at interoperability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | Unidirectional; 7.0 V VWM; SMC package (larger footprint); 600 W PPPM. | Requires correct polarity placement; better suited for higher-energy surges where board space permits. | Select when higher peak power (600 W) is needed and unidirectional protection suffices for DC-biased lines. |
| 1.5KE7.5CA | Unidirectional/bidirectional option; 7.5 V VWM; DO-201 package; 1500 W PPPM; higher VC (12.9 V). | Higher clamping voltage reduces protection margin for 5 V logic; larger package increases layout area. | Choose only if legacy DO-201 footprint compatibility is mandatory and system can tolerate 12.9 V clamping. |
Compared with SMBJ7.0A and 1.5KE7.5CA, the BZW04-7V0HE3/54 provides AEC-Q101 qualification, tighter VBR tolerance, lower VC, and DO-41 compatibility - making it optimal for space-constrained, automotive-grade 5 V signal line protection where bidirectional symmetry and reliability are essential.

FAQ
What is the polarity configuration of BZW04-7V0HE3/54?
The BZW04-7V0HE3/54 is a bidirectional TVS diode with no polarity marking - both terminals are functionally identical and conduct during either positive or negative voltage transients. This eliminates orientation concerns during PCB assembly and simplifies design for AC-coupled or floating signal lines.
Does BZW04-7V0HE3/54 meet automotive qualification standards?
Yes, BZW04-7V0HE3/54 carries the HE3 suffix, confirming full AEC-Q101 qualification per Vishay documentation (Document Number 88316, Revision 16-Sep-2021). It has passed stress tests including high-temperature reverse bias, temperature cycling, and ESD, making it suitable for under-hood and chassis-mounted automotive applications.
What is the maximum clamping voltage of BZW04-7V0HE3/54 under surge conditions?
The BZW04-7V0HE3/54 exhibits a maximum clamping voltage (VC) of 12.1 V at 33.0 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per IEC 61000-4-5 and ensures protected 5 V circuits remain within safe operating limits during standardized surge events.
Can BZW04-7V0HE3/54 be used in place of unidirectional TVS diodes?
No - BZW04-7V0HE3/54 is strictly bidirectional and must not replace unidirectional TVS diodes in DC-biased applications without circuit review. Its symmetrical V-I curve provides equal protection for both polarities, but lacks the forward conduction path of unidirectional types; using it on a DC rail may cause unintended conduction during normal operation.
What package type and lead finish does BZW04-7V0HE3/54 use?
BZW04-7V0HE3/54 uses the DO-41 (DO-204AL) axial package with matte tin-plated leads compliant with J-STD-002 and JESD22-B102. The HE3 suffix also indicates JESD201 Class 2 whisker resistance, ensuring long-term solder joint integrity in high-reliability applications.
