Product details
Overview
1.5SMC62CA-M3/57T 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 62 V breakdown voltage (VBR = 58.9–65.1 V at IT = 1.0 mA), 1500 W peak pulse power (10/1000 µs), clamping voltage of 85.0 V at 17.6 A, and operates across -65 °C to +150 °C. It is widely deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5SMC62CA-M3/57T datasheet, 1.5SMC62CA-M3/57T pinout, 1.5SMC62CA-M3/57T application, or 1.5SMC62CA-M3/57T equivalent, key selection criteria include bidirectional clamping capability, SMC (DO-214AB) package compatibility, AEC-Q101 qualification status, and thermal resistance (RθJA = 75 °C/W) under standard PCB pad layout.
Technical Context
This device functions as a voltage-clamped surge protector with symmetrical avalanche behavior in both directions, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM = 53.0 V).
The 1.5SMC62CA-M3/57T delivers fast response time (<1.0 ns), low incremental surge resistance, and meets MSL level 1 per J-STD-020 with 260 °C reflow peak. It is halogen-free and RoHS-compliant (M3 suffix), supporting automated SMT placement on standard 8.0 mm × 8.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at 1.0 mA - defines precise avalanche initiation window for predictable clamping onset |
| VWM | 53.0 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 85.0 V at 17.6 A - clamping voltage during 1500 W transient, limiting downstream stress |
| PPPM | 1500 W (10/1000 µs waveform) - peak surge energy handling capacity under standardized lightning-like pulse |
| RθJA | 75 °C/W - thermal resistance from junction to ambient, critical for derating above 25 °C ambient |
| TJ range | -65 °C to +150 °C - extended temperature operation suitable for under-hood automotive and industrial environments |
| Package | SMC (DO-214AB) - surface-mount package with 7.75 mm × 6.22 mm footprint and 2.62 mm height, optimized for high-power dissipation |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, polarity-unmarked for bidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Cathode | Current exit terminal in forward bias; functionally identical to anode in bidirectional configuration | Terminal pair forms a symmetric voltage clamp - both pins serve as interchangeable surge current paths |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR, VC, and IPPM in both polarities - eliminates need for polarity-aware routing in AC or differential lines |
| 1500 W peak pulse rating | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-earth) when mounted per recommended 8.0 mm × 8.0 mm pad layout |
| Halogen-free & RoHS-compliant (M3) | Meets environmental compliance requirements for automotive and industrial end equipment without compromising surge performance |
| AEC-Q101 qualified option | Available in HM3 variant - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| Low leakage & stable VBR | <1.0 µA at 53.0 V; ±5% VBR tolerance - ensures minimal standby power loss and repeatable protection threshold |
Applications
| Automotive Sensor Interface | Industrial PLC Analog Input |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Lower PPPM (600 W), smaller SMB package (DO-214AA), VC = 103 V @ 5.8 A | Best suited for space-constrained, lower-energy circuits (e.g., USB data lines); not rated for 1500 W surges | Select when board area is limited and peak surge energy remains below 600 W - verify clamping margin with system-level testing. |
| 1.5KE62CA | Through-hole TO-204AE (DO-41), same VBR/VC, but higher RθJA (~100 °C/W) and no M3/halogen-free option | Preferred for legacy through-hole designs or prototyping; lacks SMT automation support and modern environmental compliance | Choose only for manual assembly or backward-compatible replacements - avoid in new automotive or RoHS-mandated designs. |
Compared with SMBJ64CA and 1.5KE62CA, the 1.5SMC62CA-M3/57T uniquely combines 1500 W surge capacity, SMC surface-mount scalability, halogen-free compliance, and bidirectional symmetry - making it optimal for high-reliability automotive and industrial SMT production.

FAQ
What is the clamping voltage of the 1.5SMC62CA-M3/57T under maximum surge conditions?
The 1.5SMC62CA-M3/57T clamps to 85.0 V at its peak pulse current of 17.6 A (10/1000 µs waveform). This value is measured per standard test conditions with devices mounted on 8.0 mm × 8.0 mm copper pads. The clamping voltage directly determines the maximum stress imposed on downstream circuitry during surge events, and must be verified against the absolute maximum ratings of protected ICs.
Is the 1.5SMC62CA-M3/57T suitable for automotive applications?
Yes - the 1.5SMC62CA-M3/57T is halogen-free and RoHS-compliant (M3 suffix), and an AEC-Q101 qualified version (HM3 suffix) is available. While the M3 variant itself is not certified, its construction, thermal performance (TJ = -65 °C to +150 °C), and surge capability align with automotive subsystem requirements such as body control modules and sensor interfaces when used within validated design margins.
How does the bidirectional nature of the 1.5SMC62CA-M3/57T affect PCB layout?
The 1.5SMC62CA-M3/57T has no polarity marking and identical electrical behavior in both directions, so PCB layout requires no orientation check during placement. This simplifies automated assembly and eliminates risk of reverse installation. Layout should follow Vishay's recommended 8.0 mm × 8.0 mm copper pad dimensions per terminal to ensure rated 1500 W pulse power handling and thermal performance.
What is the maximum steady-state power dissipation for the 1.5SMC62CA-M3/57T?
The 1.5SMC62CA-M3/57T has a DC power dissipation rating (PD) of 6.5 W at TA = 50 °C on an infinite heatsink. In typical PCB applications, derating applies above 25 °C ambient - for example, at 75 °C ambient, usable PD drops to approximately 4.5 W. This rating governs continuous leakage-related heating, not transient surge energy.
Does the 1.5SMC62CA-M3/57T require external current-limiting components?
No - the 1.5SMC62CA-M3/57T operates as a self-limiting voltage clamp and does not require series resistors or fuses for basic surge suppression. However, in high-repetition-rate surge environments or where fault current must be interrupted, coordination with upstream current-limiting elements (e.g., PTCs or fuses) is recommended to prevent thermal runaway during sustained overvoltage conditions.
