Product details
Overview
1.5SMC62AHM3/I from Vishay General Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, featuring 62 V breakdown voltage (VBR = 58.9–65.1 V at 1 mA), 53.0 V stand-off voltage (VWM), and 85.0 V maximum clamping voltage (VC) at 17.6 A peak pulse current - designed for robust overvoltage protection of automotive power rails and industrial sensor interfaces.
For engineers reviewing the 1.5SMC62AHM3/I datasheet, 1.5SMC62AHM3/I pinout, 1.5SMC62AHM3/I application, or 1.5SMC62AHM3/I equivalent, this part delivers AEC-Q101 qualified surge immunity with halogen-free RoHS compliance, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive ECUs and industrial I/O modules.
Technical Context
The 1.5SMC62AHM3/I operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve sub-nanosecond response time and stable clamping under repetitive 10/1000 µs transients. Its thermal resistance (RθJA = 75 °C/W) and junction temperature limit (TJ = 150 °C) support operation on standard PCB copper pads without forced cooling.
Designed for automotive-grade reliability, it meets AEC-Q101 qualification with halogen-free construction (HM3 suffix), JESD201 Class 2 whisker resistance, and UL 94 V-0 molding compound - enabling use in under-hood environments where thermal cycling and humidity exposure are severe.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at 1 mA - defines precise avalanche onset threshold for repeatable overvoltage triggering |
| VWM | 53.0 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 85.0 V at 17.6 A - clamping voltage during 10/1000 µs surge, limiting downstream IC stress |
| PPPM | 1500 W - peak pulse power handling capability per single 10/1000 µs waveform at 0.01% duty cycle |
| IFSM | 200 A - non-repetitive forward surge current rating (8.3 ms half-sine), supporting inrush tolerance |
| TJ max | 150 °C - maximum junction temperature enabling operation in engine bay or industrial enclosures |
| RθJA | 75 °C/W - thermal resistance from junction to ambient on standard 8 mm × 8 mm copper pads |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting 12 V/24 V battery-fed microcontrollers and CAN transceivers from load dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp positive-going surges above 53 V. Use Value: Limits clamped voltage to 85 V, staying within absolute maximum ratings of automotive-grade MCUs and transceivers rated to 95 V. |
Use Scenario: Safeguarding analog outputs of pressure/temperature sensors connected to PLC analog input cards. IC Role / Device Role / Timing Role: Standoff voltage (53 V) ensures no conduction during normal 24 V loop operation; fast avalanche response (<1 ns) suppresses ESD and EFT bursts. Use Value: Prevents sensor output saturation and ADC offset errors caused by sub-microsecond transients on 4–20 mA or 0–10 V lines. |
| DC-DC Converter Input Protection | Motor Drive Gate Driver Protection |
|
Use Scenario: Shielding buck converter inputs from back-EMF spikes generated by relay coils or solenoid actuation. IC Role / Device Role / Timing Role: Placed across input capacitor to absorb repetitive 10/1000 µs pulses up to 1500 W without degradation. Use Value: Maintains system uptime by preventing input-stage MOSFET failure due to voltage overshoot exceeding 60 V rating. |
Use Scenario: Clamping Miller-induced voltage spikes on high-side gate driver supply rails in half-bridge inverters. IC Role / Device Role / Timing Role: Connected between gate driver VDD and ground to clamp positive transients before they exceed 65 V breakdown threshold. Use Value: Avoids false turn-on of power devices and ensures reliable PWM timing integrity under fast-switching conditions. |
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-E3/52 | Lower peak power (600 W), SMB package (smaller footprint), VBR = 71.1–78.6 V, VC = 103 V @ 5.8 A | Not AEC-Q101 qualified; suitable for commercial-grade consumer or computing applications only | Select when board space is constrained and surge energy is ≤600 W; verify clamping margin against downstream device ratings. |
| 1.5KE62A | Through-hole DO-201 package, same VBR/VC specs, but higher RθJA (~50 °C/W on larger pads), no AEC-Q101 or halogen-free certification | Limited to non-automotive industrial or legacy designs requiring through-hole assembly | Choose only if SMT assembly is unavailable; expect reduced thermal performance and no automotive qualification. |
Compared with SMBJ64A-E3/52 and 1.5KE62A, the 1.5SMC62AHM3/I uniquely combines AEC-Q101 qualification, halogen-free compliance, 1500 W surge capacity, and SMC package scalability - making it the only option qualified for next-generation automotive power distribution modules and industrial safety-critical controllers.

FAQ
What is the clamping voltage of the 1.5SMC62AHM3/I at its rated peak pulse current?
The 1.5SMC62AHM3/I has a maximum clamping voltage (VC) of 85.0 V at its rated peak pulse current (IPPM) of 17.6 A, measured under the standardized 10/1000 µs waveform. This value ensures that downstream components exposed to the protected line remain within their absolute maximum voltage ratings during surge events. The 1.5SMC62AHM3/I maintains this clamping performance across its qualified operating temperature range.
Is the 1.5SMC62AHM3/I AEC-Q101 qualified and what does the 'HM3' suffix indicate?
Yes, the 1.5SMC62AHM3/I is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control, body electronics, and ADAS subsystems. The 'HM3' suffix denotes halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance - meeting stringent environmental and reliability requirements for modern automotive supply chains. This qualification is explicitly documented in Vishay's 1.5SMC series datasheet revision 09-Mar-2026.
What is the standoff voltage (VWM) of the 1.5SMC62AHM3/I and how does it relate to system operating voltage?
The 1.5SMC62AHM3/I has a maximum reverse standoff voltage (VWM) of 53.0 V, meaning it remains non-conductive with leakage <1 µA up to this DC or RMS voltage. This allows safe integration into 48 V nominal automotive systems or 36 V industrial power rails, providing margin below the 58.9 V minimum breakdown voltage. Engineers must ensure normal operating voltage stays ≤53.0 V to prevent premature conduction and power loss in the 1.5SMC62AHM3/I.
Can the 1.5SMC62AHM3/I be used in bidirectional configurations?
No, the 1.5SMC62AHM3/I is a unidirectional TVS diode, identified by the 'A' suffix and cathode band marking. Bidirectional variants use the 'CA' suffix (e.g., 1.5SMC62CA). Using the 1.5SMC62AHM3/I in reverse-biased configurations will not provide symmetrical clamping and may fail catastrophically under negative transients. For bidirectional protection, select the correctly specified 1.5SMC62CA variant instead of the 1.5SMC62AHM3/I.
What is the thermal resistance and recommended pad layout for optimal performance of the 1.5SMC62AHM3/I?
The 1.5SMC62AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal - as defined in Vishay's datasheet Figure 2. To maintain reliability under repetitive surges, PCB layout must replicate this minimum pad area; reducing copper area increases junction temperature and de-rates peak pulse power. The 1.5SMC62AHM3/I does not require external heatsinking under these conditions.
