Product details
Overview
BZW04-110HE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for circuit-level ESD and surge protection. It features 111 V standoff voltage (VWM), 124–137 V breakdown range (VBR at 1 mA), 179 V clamping voltage at 2.2 A peak pulse current (IPPM), and 400 W peak pulse power rating with 10/1000 μs waveform. It is AEC-Q101 qualified and used to protect automotive sensor signal lines against inductive switching transients.
For engineers reviewing the BZW04-110HE3/54 datasheet, BZW04-110HE3/54 pinout, BZW04-110HE3/54 application, or BZW04-110HE3/54 equivalent, this page delivers verified electrical parameters, mechanical package details, real-world use cases in automotive and industrial systems, and validated alternative parts for design continuity and supply resilience.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical VBR, VC, and IPPM specifications in forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 μA at VWM), while the DO-41 package supports manual and automated assembly with J-STD-002-compliant matte tin leads.
The device sustains 400 W peak pulse power under standardized 10/1000 μs transients at ≤0.01% duty cycle and derates linearly above 25 °C ambient per Fig. 2. Junction temperature range spans −55 °C to +175 °C, enabling deployment in under-hood automotive environments and industrial control cabinets where thermal cycling is severe.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 111 V - Maximum continuous reverse operating voltage before conduction begins; defines safe working margin for 12 V/24 V automotive signal lines. |
| VBR (min/max) | 124 V / 137 V at 1 mA - Confirmed breakdown threshold range; ensures reliable triggering during fast-rising transients without premature conduction. |
| VC @ IPPM | 179 V at 2.2 A - Clamped voltage during full 400 W surge; limits downstream IC stress to survivable levels per IEC 61000-4-5 Level 3. |
| PPPM | 400 W - Peak pulse power handling with 10/1000 μs waveform; meets ISO 7637-2 Pulse 1/2/5a requirements for automotive electronics. |
| IPPM | 2.2 A - Peak pulse current capability; sufficient to absorb typical load-dump and inductive kick energy in CAN/LIN bus nodes. |
| TJ max | +175 °C - Maximum junction temperature; enables operation in high-ambient engine bay locations without thermal shutdown. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including HTOL, TC, HAST, and ESD testing; suitable for ASIL-B supporting functions. |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; no polarity marking for bidirectional configuration; lead finish: matte tin, solderable per J-STD-002 and JESD22-B102; UL 94 V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional transient conduction path | No designated anode/cathode; terminals interchangeable; conducts identically in either direction upon overvoltage event. |
| Lead 1 | Connection to protected line (e.g., CAN_H) | Direct series or shunt placement between signal line and ground; requires minimal trace inductance for sub-nanosecond response. |
| Lead 2 | Connection to reference plane (e.g., chassis ground) | Low-inductance grounding essential; recommended via short, wide trace or direct via to internal ground plane to preserve clamping speed. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable, repeatable breakdown characteristics across temperature and lifetime; eliminates surface degradation under repeated surges. |
| 400 W peak pulse power (10/1000 μs) | Supports robust protection against ISO 7637-2 Pulse 5a (load dump) in 12 V systems without derating or parallel devices. |
| AEC-Q101 qualification | Validates suitability for automotive applications including powertrain, body control, and ADAS sensor interfaces without additional qualification effort. |
| Low incremental surge resistance | Minimizes VC overshoot during fast transients; measured clamping voltage remains tightly controlled at 179 V even at full IPPM. |
| RoHS-compliant HE3 suffix | Indicates AEC-Q101 qualification and JESD201 Class 2 whisker resistance; required for automotive production traceability and long-term reliability. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | DO-214AA package; 110 V VWM; 122–135 V VBR; 187 V VC @ 2.1 A; same 400 W rating but higher clamping voltage. | Surface-mount only; requires PCB rework for through-hole replacement; better suited for space-constrained telecom modules than legacy automotive harnesses. | Select when board area is constrained and reflow assembly is available; verify thermal pad layout matches SMBJ footprint. |
| 1.5KE110CA | DO-201AD package; 110 V VWM; 122–135 V VBR; 187 V VC @ 2.1 A; 1500 W rating but larger size and slower response due to higher junction capacitance. | Higher power rating but 3× larger DO-201AD body; not AEC-Q101 qualified; unsuitable for automotive under-hood mounting. | Use only in non-automotive industrial settings where surge amplitude exceeds 400 W and lead-free wave solder compatibility is required. |
Compared with BZW04-110HE3/54, SMBJ110CA offers SMT compatibility at the cost of higher clamping and no AEC-Q101 validation, while 1.5KE110CA trades automotive qualification and compact DO-41 form factor for raw power headroom-making BZW04-110HE3/54 the optimal choice for AEC-compliant, space-aware, and thermally demanding deployments.

FAQ
What is the clamping voltage of BZW04-110HE3/54 under maximum surge conditions?
The BZW04-110HE3/54 exhibits a maximum clamping voltage (VC) of 179 V at its rated peak pulse current of 2.2 A using the standard 10/1000 μs waveform. This value is measured per IEC 61000-4-5 test conditions and represents the upper limit of voltage seen by downstream circuitry during a full-power transient event. The BZW04-110HE3/54 maintains this clamping performance across its qualified temperature range and after repeated surge exposure due to its glass-passivated junction.
Is BZW04-110HE3/54 suitable for automotive applications?
Yes, BZW04-110HE3/54 is AEC-Q101 qualified and explicitly intended for automotive use. Its DO-41 package, −55 °C to +175 °C operating range, and robust 400 W surge rating meet requirements for engine control units, body electronics, and sensor interfaces. The HE3 suffix confirms compliance with JESD201 Class 2 whisker testing and RoHS standards required for automotive production. BZW04-110HE3/54 has been validated for ISO 7637-2 Pulse 1, 2a, and 5a immunity in 12 V systems.
How does the bidirectional nature of BZW04-110HE3/54 affect its circuit implementation?
As a bidirectional TVS, BZW04-110HE3/54 has no polarity marking and conducts identically in both directions-making it ideal for AC-coupled or differential signal lines like CAN, LIN, or RS-485. It is installed as a shunt device between the protected line and ground, with no need to observe anode/cathode orientation. This simplifies layout and eliminates risk of incorrect placement during manual or automated assembly. The BZW04-110HE3/54 achieves symmetrical VBR and VC values in both polarities per datasheet Table "BIDIRECTIONAL TYPES".
What is the meaning of the "HE3/54" suffix in BZW04-110HE3/54?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD201 Class 2 whisker resistance; "/54" specifies the packaging format: 13-inch paper tape and reel containing 550 units. This ordering code ensures traceability to Vishay's qualified manufacturing lot and guarantees compliance with automotive supply chain requirements. BZW04-110HE3/54 is distinct from commercial-grade "E3" variants, which lack AEC-Q101 validation and Class 2 whisker testing.
Can BZW04-110HE3/54 replace unidirectional TVS diodes in existing designs?
No-BZW04-110HE3/54 is strictly bidirectional and must not be substituted for unidirectional TVS diodes without circuit review. Unidirectional parts include a cathode band and conduct only in reverse bias; replacing them with BZW04-110HE3/54 would allow forward conduction during normal operation, potentially disrupting bias networks or causing leakage paths. If bidirectional protection is required, confirm that the protected node is referenced to ground and does not rely on DC polarity for functionality before deploying BZW04-110HE3/54.
