Product details
Overview
1.5SMC62A-M3/57T from Vishay General Semiconductor is a unidirectional surface-mount 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 1 mA), 53.0 V stand-off voltage (VWM), 85.0 V maximum clamping voltage (VC) at 17.6 A peak pulse current, and 1500 W peak pulse power capability with 10/1000 µs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and DC power rail protection.
For engineers reviewing the 1.5SMC62A-M3/57T datasheet, 1.5SMC62A-M3/57T pinout, 1.5SMC62A-M3/57T application, or 1.5SMC62A-M3/57T equivalent, this part delivers verified AEC-Q101-qualified surge immunity in halogen-free, RoHS-compliant SMC (DO-214AB) packaging - critical for high-reliability designs requiring repeatable clamping performance under lightning-induced transients and inductive switching events.
Technical Context
The 1.5SMC62A-M3/57T operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve sub-nanosecond response time and low incremental surge resistance. Its clamping behavior is defined by a tightly controlled VBR tolerance (±5%) and temperature coefficient of +0.104 %/°C, ensuring stable protection thresholds across -65 °C to +150 °C operating range.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it sustains 200 A non-repetitive forward surge current (IFSM) and dissipates 6.5 W under continuous operation at 50 °C ambient - with thermal resistance of 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-leads), enabling predictable thermal management in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at 1 mA - defines precise avalanche initiation window for reliable overvoltage triggering |
| VWM | 53.0 V - maximum continuous reverse voltage before leakage exceeds 1 μA, setting safe operating margin |
| VC @ IPPM | 85.0 V at 17.6 A - clamped voltage during 10/1000 µs transient, limiting downstream stress |
| PPPM | 1500 W - peak pulse power handling capacity under standardized surge waveform |
| IFSM | 200 A - single half-sine surge current rating (8.3 ms), supporting motor drive and relay coil suppression |
| TJ max | +150 °C - maximum junction temperature, enabling use in under-hood automotive and industrial environments |
| Package | SMC (DO-214AB) - industry-standard 2-pin surface-mount outline with 7.75 mm × 6.22 mm footprint |
Pinout & Package

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and chassis ground, clamping transients before they reach sensitive input stages. Use Value: Maintains signal integrity during 12 V/24 V system load dump events (up to 35 V, 400 ms) while holding VC ≤ 85 V at 17.6 A. |
Use Scenario: Safeguarding digital input modules in programmable logic controllers exposed to relay contact bounce and field wiring surges. IC Role / Device Role / Timing Role: Front-end transient suppressor on 24 V DC input channels, absorbing repetitive inductive spikes from solenoid drivers. Use Value: Withstands 0.01% duty cycle surges up to 1500 W, extending module MTBF and eliminating false triggers in noisy factory environments. |
| DC Power Rail Protection | Consumer Power Adapter Output |
Use Scenario: Secondary-side overvoltage clamp on 48 V PoE++ or telecom rectifier outputs subjected to hot-swap and cable discharge events. IC Role / Device Role / Timing Role: Standoff-rated TVS connected cathode-to-rail, conducting only during overvoltage excursions above 53 V. Use Value: Limits rail excursion to ≤85 V during 10/1000 µs surges, preventing damage to downstream DC-DC converters and FETs. |
Use Scenario: Output-stage surge protection in USB-C PD adapters and wall chargers compliant with UL 62368-1 transient immunity. IC Role / Device Role / Timing Role: Final-stage TVS on regulated 5–20 V output, suppressing ESD and conducted noise coupled from mains input. Use Value: Delivers <1 μA leakage at 53 V, preserving no-load efficiency while meeting IEC 61000-4-2 ±8 kV contact discharge requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A | Lower PPPM (600 W), same VWM/VBR range, SMB package (smaller footprint, higher RθJA) | Preferred for space-constrained consumer electronics where 600 W surge margin suffices | Select when board area is limited and peak surge energy is ≤600 W; verify thermal derating due to higher junction-to-ambient resistance |
| 1.5KE62A | Through-hole DO-201 package, identical electrical specs but incompatible with SMT assembly and higher inductance | Suitable for prototyping, legacy repair, or high-vibration environments where mechanical retention outweighs assembly efficiency | Choose only for manual soldering or ruggedized systems; not recommended for automated production or high-frequency transient suppression |
Compared with SMBJ64A and 1.5KE62A, the 1.5SMC62A-M3/57T uniquely balances 1500 W surge capacity, SMC surface-mount compatibility, AEC-Q101 qualification, and halogen-free construction - making it the optimal choice for volume-manufactured automotive and industrial power electronics requiring zero-layout compromise and full regulatory alignment.

FAQ
What is the maximum clamping voltage of the 1.5SMC62A-M3/57T under a 10/1000 µs surge?
The 1.5SMC62A-M3/57T exhibits a maximum clamping voltage (VC) of 85.0 V when subjected to its rated peak pulse current of 17.6 A using the standardized 10/1000 µs waveform. This value is guaranteed per Vishay's datasheet (Document Number: 88303, Rev. 09-Mar-2026) and represents the upper limit of voltage seen by protected circuitry during worst-case transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the 1.5SMC62A-M3/57T qualified for automotive applications?
Yes, the 1.5SMC62A-M3/57T is AEC-Q101 qualified, as confirmed by Vishay's ordering code structure (M3 suffix with AEC-Q101 grade denoted in documentation). It meets the stress test requirements for temperature cycling, humidity bias, and surge endurance mandated for automotive electronic control units, body modules, and sensor interfaces - making it suitable for under-hood and cabin applications where reliability is non-negotiable.
What does the "M3" suffix indicate in 1.5SMC62A-M3/57T?
The "M3" suffix in 1.5SMC62A-M3/57T designates a halogen-free, RoHS-compliant commercial-grade variant with matte tin-plated leads and JESD 201 Class 2 whisker resistance. Unlike the "E3" variant, M3 ensures full compliance with automotive and industrial environmental directives without sacrificing electrical or thermal performance - and is explicitly listed in Vishay's ordering table as compatible with AEC-Q101 qualification when paired with appropriate revision codes.
How does the 1.5SMC62A-M3/57T differ from bidirectional TVS diodes like 1.5SMC62CA?
The 1.5SMC62A-M3/57T is unidirectional and features polarity marking (cathode band), allowing it to block forward voltage up to ~1.5 V while clamping only in reverse. In contrast, 1.5SMC62CA is bidirectional with symmetrical clamping in both directions and no polarity marking. This makes the 1.5SMC62A-M3/57T ideal for DC power rails and single-polarity signal lines, whereas the CA version suits AC-coupled or differential bus protection where polarity reversal may occur.
What is the thermal resistance specification for the 1.5SMC62A-M3/57T?
The 1.5SMC62A-M3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the minimum recommended 8.0 mm × 8.0 mm copper pad per terminal, and a junction-to-leads resistance (RθJL) of 15 °C/W. These values are essential for calculating steady-state junction temperature rise under continuous power dissipation (PD = 6.5 W) and must be applied with actual PCB copper area and airflow conditions to ensure operation remains within the -65 °C to +150 °C TJ limit.
