Product details
Overview
1.5SMC62AHM3_A/H 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 rating with 10/1000 µs waveform - deployed in automotive ECUs, industrial I/O modules, and DC power input stages.
For engineers reviewing the 1.5SMC62AHM3_A/H datasheet, 1.5SMC62AHM3_A/H pinout, 1.5SMC62AHM3_A/H application, or 1.5SMC62AHM3_A/H equivalent, key selection considerations include its AEC-Q101 qualification, halogen-free RoHS-compliant HM3 suffix, SMC (DO-214AB) package thermal performance (RθJA = 75 °C/W), and unidirectional polarity with cathode band marking.
Technical Context
This TVS diode operates as a clamping device that diverts transient energy to ground when reverse voltage exceeds VWM (53.0 V), entering avalanche conduction at VBR (min 58.9 V). Its low incremental surge resistance ensures stable clamping under repetitive 10/1000 µs surges up to 0.01% duty cycle.
Designed for high-reliability environments, the 1.5SMC62AHM3_A/H meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), supports 200 A non-repetitive forward surge (8.3 ms half-sine), and maintains operation across –65 °C to +150 °C junction temperature range with 0.104 %/°C VBR temperature coefficient.
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 threshold for repeatable clamping behavior |
| VWM | 53.0 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 85.0 V at 17.6 A - clamping voltage during 1500 W transient, limiting downstream IC stress |
| PPPM | 1500 W - peak pulse power handling with 10/1000 µs waveform, enabling lightning and ESD surge immunity |
| IFSM | 200 A - single half-sine surge current rating (8.3 ms), supporting inductive load switching protection |
| TJ max | +150 °C - maximum junction temperature, allowing use in under-hood automotive and high-ambient industrial settings |
| RθJA | 75 °C/W - thermal resistance from junction to ambient on standard 8.0 mm × 8.0 mm copper pads |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; polarity indicated by cathode band on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient return path | Connected to protected line (e.g., 12 V rail); conducts during positive transients when used in reverse-biased configuration |
| Cathode | Avalanche conduction terminal | Marked with band; tied to system ground to clamp overvoltage by shunting surge current to earth reference |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces |
| Halogen-free & RoHS-compliant (HM3) | Meets environmental compliance requirements for global OEM supply chains without compromising surge robustness |
| 1500 W peak pulse power (10/1000 µs) | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-to-earth) in properly decoupled circuits |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes voltage overshoot during clamping, reducing risk of MOSFET gate oxide damage or MCU brownout |
| MSL Level 1 moisture sensitivity | Enables standard SMT reflow without baking, simplifying manufacturing for high-volume PCB assembly |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Clamping |

Use Scenario: -48 V DC distribution bus feeding multiple line cards in central office equipment. IC Role / Device Role / Timing Role: Distributed TVS array across backplane connectors to localize surge energy and reduce ground bounce. Use Value: Low RθJA (75 °C/W) enables reliable operation at 70 °C ambient without derating, maintaining clamping integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60A | Lower PPPM (400 W), SMA package (higher RθJA ≈ 100 °C/W), same VWM/VBR range | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a or IEC 61000-4-5 Level 4 | Select only for space-constrained consumer-grade designs where 1500 W capability is not required. |
| 1.5KE62A | Through-hole DO-201 package, identical electrical specs but no AEC-Q101 or MSL Level 1 rating | Not suitable for automated SMT production or automotive under-hood deployment due to leaded construction | Choose for legacy through-hole boards or prototyping where reflow compatibility and automotive qualification are irrelevant. |
Compared with SMAJ60A and 1.5KE62A, the 1.5SMC62AHM3_A/H uniquely combines AEC-Q101 qualification, halogen-free compliance, SMC package thermal efficiency, and full 1500 W surge capacity - making it the only option qualified for volume automotive SMT production requiring zero layout change from legacy 1.5SMC designs.

FAQ
What is the clamping voltage of the 1.5SMC62AHM3_A/H under maximum rated surge current?
The 1.5SMC62AHM3_A/H exhibits a maximum clamping voltage (VC) of 85.0 V when subjected to its peak pulse current (IPPM) of 17.6 A with a 10/1000 µs waveform. This value is measured per Figure 1 in Vishay Document 88303 and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The 1.5SMC62AHM3_A/H maintains this clamping performance across its specified operating temperature range.
Is the 1.5SMC62AHM3_A/H qualified for automotive applications?
Yes, the 1.5SMC62AHM3_A/H carries AEC-Q101 qualification, confirmed by its HM3 suffix and documentation in Vishay's 1.5SMC Series datasheet (Rev. 09-Mar-2026, Doc. #88303). This certification validates its reliability for automotive powertrain, chassis, and body electronics applications, including exposure to temperature cycling, mechanical shock, and humidity testing per AEC standards. The 1.5SMC62AHM3_A/H is explicitly listed in the "AEC-Q101 qualified available" feature section.
What does the "HM3" suffix indicate in 1.5SMC62AHM3_A/H?
The "HM3" suffix in 1.5SMC62AHM3_A/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Per Vishay's ordering information table (page 3), HM3 devices meet JESD 201 Class 2 whisker resistance and UL 94 V-0 flammability requirements. The "_A/H" further specifies packaging: 7-inch tape-and-reel (H) with revision code A. This distinguishes it from E3/M3 commercial variants and HE3/HM3 variants with different reel sizes or revisions.
How does the thermal performance of the 1.5SMC62AHM3_A/H compare to smaller packages like SMAJ?
The 1.5SMC62AHM3_A/H delivers superior thermal performance versus SMAJ-series devices, with a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W on standard 8.0 mm × 8.0 mm copper pads - compared to ~100 °C/W for SMAJ60A. This 25% lower RθJA allows the 1.5SMC62AHM3_A/H to sustain higher average power dissipation and maintain clamping stability during repetitive surges in high-ambient environments such as automotive engine bays or industrial enclosures.
Can the 1.5SMC62AHM3_A/H be used in bidirectional configurations?
No, the 1.5SMC62AHM3_A/H is a unidirectional TVS diode, as indicated by its "A" suffix and cathode band marking. Bidirectional operation requires a "CA" suffix (e.g., 1.5SMC62CA). Using the 1.5SMC62AHM3_A/H in reverse-biased signal paths without proper polarity alignment will result in forward conduction and potential device failure. For AC or differential line protection, select the corresponding CA variant instead of the 1.5SMC62AHM3_A/H.
