Product details
Overview
1.5SMC62AHE3/57T from Vishay General Semiconductor is a unidirectional 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 rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5SMC62AHE3/57T datasheet, 1.5SMC62AHE3/57T pinout, 1.5SMC62AHE3/57T application, or 1.5SMC62AHE3/57T equivalent, key selection criteria include unidirectional polarity, SMC (DO-214AB) package compatibility, AEC-Q101 qualification, low incremental surge resistance, and clamping performance under repetitive transients in harsh environments.
Technical Context
The 1.5SMC62AHE3/57T operates as a silicon avalanche diode with glass-passivated junction, delivering fast response time (<1 ns) and stable clamping during ESD, lightning-induced surges, and inductive switching events. Its unidirectional configuration enables cathode-referenced protection on DC rails and power inputs.
Thermal design relies on RθJA = 75 °C/W and RθJL = 15 °C/W, with derating above TA = 25 °C per Fig. 2; it supports 200 A non-repetitive forward surge (8.3 ms half-sine) and maintains operation across –65 °C to +150 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at IT = 1 mA - defines precise avalanche initiation threshold for repeatable clamping onset |
| VWM | 53.0 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 85.0 V at 17.6 A - clamped voltage during 1500 W transient, limiting downstream stress |
| PPPM | 1500 W (10/1000 µs) - peak surge energy handling capacity for industrial-grade immunity |
| IFSM | 200 A (8.3 ms half-sine) - withstands high-energy inrush without failure in power supply inputs |
| TJ max. | +150 °C - enables deployment in under-hood automotive and high-temperature industrial enclosures |
| AEC-Q101 | Qualified - validated for automotive electronics per stress test requirements (HTOL, TC, HAST, etc.) |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; meets UL 94 V-0 flammability rating and MSL level 1 (260 °C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias | Connected to protected line's lower-potential side (e.g., GND or return path) in unidirectional configuration |
| Cathode | Current exit terminal in forward bias; marked with band | Connected to protected line's higher-potential side (e.g., VIN, signal rail); defines clamping polarity |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power | Enables single-device protection against IEC 61000-4-5 Level 4 (4 kV/2 Ω) surges without cascaded stages |
| Glass-passivated junction | Ensures long-term reliability and stable VBR drift < ±5 % over lifetime in humid or thermally cycled environments |
| AEC-Q101 qualification | Validates suitability for automotive body control modules, ADAS sensors, and infotainment power rails |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a), improving system margin |
| MSL Level 1 rating | Allows standard SMT assembly without dry-pack or baking, reducing manufacturing cost and complexity |
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 jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor VCC and GND, clamping transients before they reach ASIC input pins. Use Value: Limits voltage to ≤85.0 V during 1500 W surges, preventing latch-up or gate oxide damage in 5 V/12 V sensor ICs. |
Use Scenario: Safeguarding digital input channels of programmable logic controllers exposed to field wiring induced surges. IC Role / Device Role / Timing Role: Standoff-rated TVS on 24 V DC input lines, absorbing inductive kickback from solenoid/relay coils. Use Value: Maintains VWM = 53.0 V while clamping to 85.0 V, ensuring compatibility with 24 V logic thresholds and avoiding false triggering. |
| Power Supply Input Protection | Telecom Line Interface Protection |
|
Use Scenario: Secondary-side overvoltage suppression on DC-DC converter outputs feeding sensitive microcontrollers or FPGAs. IC Role / Device Role / Timing Role: Cathode-connected to regulated output rail; absorbs overshoot from regulator instability or hot-swap events.

Use Scenario: Front-end protection for Ethernet PHY power supplies and auxiliary bias rails in network switches/routers. IC Role / Device Role / Timing Role: Unidirectional TVS on 3.3 V/5 V bias lines, suppressing EFT/burst noise coupled via shared chassis ground. Use Value: Leverages 1 µA leakage at 53.0 V to avoid loading low-current bias networks while delivering 1500 W surge headroom. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A-E3/57T | Lower PPPM (400 W), smaller SMA package (DO-214AC), VC = 103 V @ 3.5 A | Not AEC-Q101 qualified; suited for cost-sensitive consumer electronics, not automotive | Select when board space is constrained and surge energy is ≤400 W; verify thermal margin due to higher RθJA |
| 1.5KE62A-E3/54 | Through-hole TO-204AA (DO-41), same VBR/VC, PPPM = 1500 W, no AEC-Q101 | Lacks SMT compatibility and automotive qualification; used in legacy industrial power supplies | Choose only for through-hole prototyping or repair; not recommended for new AEC-Q101-compliant designs |
Compared with SMAJ64A-E3/57T and 1.5KE62A-E3/54, the 1.5SMC62AHE3/57T uniquely combines SMC surface-mount form factor, 1500 W capability, and AEC-Q101 qualification - making it the only drop-in option for production automotive PCBs requiring zero layout change and certified reliability.

FAQ
What is the clamping voltage of the 1.5SMC62AHE3/57T under maximum surge conditions?
The 1.5SMC62AHE3/57T exhibits a maximum clamping voltage (VC) of 85.0 V at its rated peak pulse current of 17.6 A, measured using the standardized 10/1000 µs double-exponential waveform. This value ensures downstream circuitry remains within safe operating limits during high-energy transients, and is guaranteed across the full operating temperature range.
Is the 1.5SMC62AHE3/57T suitable for automotive applications?
Yes, the 1.5SMC62AHE3/57T is AEC-Q101 qualified and explicitly designated for automotive use with the "HE3" suffix. It has undergone stress testing including high-temperature operating life, temperature cycling, and humidity bias HAST, making it appropriate for engine control units, ADAS camera modules, and body electronics where reliability under thermal and electrical stress is mandatory.
What does the "HE3" suffix indicate in 1.5SMC62AHE3/57T?
The "HE3" suffix in 1.5SMC62AHE3/57T denotes RoHS-compliant construction with AEC-Q101 qualification and matte tin-plated leads meeting JESD 201 Class 2 whisker resistance. It distinguishes this variant from commercial-grade "E3" parts and confirms compliance with automotive reliability and environmental standards.
How does the 1.5SMC62AHE3/57T differ from bidirectional TVS diodes like 1.5SMC62CAHE3/57T?
The 1.5SMC62AHE3/57T is unidirectional and features polarity marking (cathode band), allowing it to protect DC rails with defined voltage reference. In contrast, 1.5SMC62CAHE3/57T is bidirectional, symmetric in both directions, and used for AC lines or differential signals like RS-485 - the 1.5SMC62AHE3/57T is not interchangeable without circuit redesign.
What is the thermal resistance profile of the 1.5SMC62AHE3/57T?
The 1.5SMC62AHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-leads resistance (RθJL) of 15 °C/W, measured on the recommended 8.0 mm × 8.0 mm copper pad layout. These values enable accurate thermal modeling for PCB layout and derating calculations above 25 °C ambient.
