Product details
Overview
1.5SMC220CAHE3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 220 V standoff voltage (VWM), 231 V minimum breakdown voltage (VBR), 328 V maximum clamping voltage (VC) at 4.6 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5SMC220CAHE3/57T datasheet, 1.5SMC220CAHE3/57T pinout, 1.5SMC220CAHE3/57T application, or 1.5SMC220CAHE3/57T equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification, SMC (DO-214AB) package thermal performance, and compliance with UL 497B surge protector requirements.
Technical Context
This device operates as a voltage-clamped shunt protector: during transients exceeding VWM (220 V), it avalanches symmetrically in both directions to clamp voltage at ≤328 V while diverting up to 4.6 A (10/1000 μs). Its glass-passivated junction ensures stable breakdown and low leakage (<1 μA at VWM).
Thermally, it delivers 6.5 W steady-state power dissipation on infinite heatsink at 50 °C and exhibits RθJA = 75 °C/W and RθJL = 15 °C/W - enabling reliable operation in compact PCB layouts with 8.0 mm × 8.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 220 V - maximum continuous reverse voltage before conduction begins in either direction |
| VBR (Breakdown Voltage) | 209–231 V at 1 mA - guaranteed avalanche initiation range under standardized test conditions |
| VC (Clamping Voltage) | 328 V at IPPM = 4.6 A (10/1000 μs) - peak voltage seen by protected circuit during worst-case surge |
| PPPM (Peak Pulse Power) | 1500 W - surge energy handling capacity defined per 10/1000 μs waveform, duty cycle ≤0.01 % |
| ID (Reverse Leakage) | <1 μA at 220 V - minimal standby power loss and signal integrity impact in high-impedance circuits |
| TJ max. | 150 °C - maximum junction temperature enabling use in under-hood automotive environments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
Pinout & Package
Package: SMC (DO-214AB) - surface-mount, low-profile case with matte tin-plated leads, UL 94 V-0 molding compound, MSL Level 1 (260 °C reflow peak), and 0.211 g unit weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; common terminal in bidirectional configuration | No polarity marking - symmetrical terminals enable identical connection regardless of signal direction |
| Cathode | Current exit point in forward bias; common terminal in bidirectional configuration | No band or marking - device functions identically with either terminal connected to line or ground |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CAHE3/52T | Lower PPPM (600 W), same VWM/VBR/VC, SMB (DO-214AA) package - 30% smaller footprint, higher RθJA (100 °C/W) | Preferred where board space is constrained and surge energy is limited to IEC 61000-4-2/4-4 levels | Select when thermal margin allows higher junction temperature rise and layout cannot accommodate SMC pad size. |
| 1.5KE220CA | Through-hole DO-201AE package, identical electrical specs but no AEC-Q101 qualification, higher mounting thermal resistance | Suitable for prototyping, legacy industrial designs, or non-automotive cost-sensitive applications | Choose only for non-automotive use cases where automated SMT assembly is not required and lifecycle validation is not mandated. |
Compared with SMBJ220CAHE3/52T and 1.5KE220CA, the 1.5SMC220CAHE3/57T provides superior surge energy handling in an AEC-Q101-qualified SMT package - making it the optimal choice for production automotive and high-reliability industrial systems requiring validated long-term stability.

FAQ
What is the clamping voltage of the 1.5SMC220CAHE3/57T under standard test conditions?
The 1.5SMC220CAHE3/57T has a maximum clamping voltage (VC) of 328 V when subjected to a 10/1000 μs waveform with a peak pulse current (IPPM) of 4.6 A. This value is measured per JEDEC standards and reflects the highest voltage the protected circuit will experience during such a transient event. The 1.5SMC220CAHE3/57T maintains this clamping performance bidirectionally and is validated across its full operating temperature range.
Is the 1.5SMC220CAHE3/57T qualified for automotive applications?
Yes, the 1.5SMC220CAHE3/57T carries AEC-Q101 qualification, confirmed by Vishay's documentation and ordering code suffix "HE3". It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD verification - making it suitable for under-hood and cabin electronics where reliability under thermal and mechanical stress is critical. The 1.5SMC220CAHE3/57T meets these requirements without derating in standard mounting configurations.
How does the bidirectional design of the 1.5SMC220CAHE3/57T affect PCB layout?
The 1.5SMC220CAHE3/57T has no polarity marking and identical electrical behavior in both directions, eliminating orientation constraints during placement. Engineers can route either terminal to line or ground without functional impact - simplifying layout for differential signals, AC lines, or floating buses. This symmetry also avoids single-point failure modes in unbalanced surge paths. The 1.5SMC220CAHE3/57T requires only standard SMC (DO-214AB) footprints with 8.0 mm × 8.0 mm copper pads per terminal for rated power handling.
What is the maximum steady-state power dissipation for the 1.5SMC220CAHE3/57T?
The 1.5SMC220CAHE3/57T is rated for 6.5 W of steady-state power dissipation when mounted on an infinite heatsink at ambient temperature of 50 °C. At 25 °C ambient, derating curves indicate ~7.5 W is achievable, but real-world PCB thermal design must account for RθJA = 75 °C/W. For continuous operation, designers should limit average power to ≤1 W unless enhanced copper pour or thermal vias are implemented. The 1.5SMC220CAHE3/57T is intended primarily for transient, not continuous, power dissipation.
Does the 1.5SMC220CAHE3/57T meet UL safety standards?
Yes, the 1.5SMC220CAHE3/57T is UL Recognized under file E136766 for both unidirectional and bidirectional configurations, compliant with UL 497B for signal line protectors. This certification covers dielectric strength, flammability (UL 94 V-0 molding compound), and surge endurance - confirming suitability for end-equipment safety approvals in North America. The 1.5SMC220CAHE3/57T achieves this without external components or special mounting, supporting streamlined regulatory submissions.
