Product details
Overview
1.5SMC62AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, designed for high-energy surge protection. It features a 62 V breakdown voltage (VBR = 58.9–65.1 V at IT = 1.0 mA), 53.0 V stand-off voltage (VWM), and clamps transients to ≤85.0 V at 17.6 A peak pulse current (IPPM) under 10/1000 µs waveform - deployed on power rails and signal lines of automotive ECUs and industrial sensor interfaces.
For engineers reviewing the 1.5SMC62AHM3_A/I datasheet, 1.5SMC62AHM3_A/I pinout, 1.5SMC62AHM3_A/I application, or 1.5SMC62AHM3_A/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), clamping performance, and halogen-free RoHS-compliant sourcing details - all critical for ESD/surge protection design-in and BOM validation.
Technical Context
The 1.5SMC62AHM3_A/I operates as a unidirectional avalanche diode with glass-passivated junction, enabling fast response (<1 ns) to transient overvoltages while maintaining low incremental surge resistance. Its 1500 W peak pulse power rating (10/1000 µs) and 200 A IFSM capability support robust protection against lightning-induced surges and inductive switching spikes in DC power systems.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads, it meets MSL Level 1 per J-STD-020 (peak reflow 260 °C) and is qualified to AEC-Q101 for automotive applications. The cathode band denotes polarity, and its thermal resistance profile (RθJL = 15 °C/W) supports reliable operation up to TJ = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at IT = 1.0 mA - defines precise avalanche onset threshold for predictable clamping behavior |
| VWM | 53.0 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | ≤85.0 V at IPPM = 17.6 A (10/1000 µs) - ensures protected ICs see no more than 85 V during worst-case surge |
| PPPM | 1500 W - sustains single high-energy transients without failure, suitable for ISO 7637-2 Pulse 5a/b compliance |
| IFSM | 200 A (8.3 ms half-sine) - withstands repetitive load-dump events in 12 V automotive systems |
| TJ max. | +150 °C - enables deployment in under-hood environments and high-ambient industrial enclosures |
| RθJA | 75 °C/W - determines required PCB copper area for thermal management at 6.5 W steady-state dissipation |

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-E3/52T (Vishay) | Lower PPPM (600 W), SMB package (smaller footprint), VBR = 71.1–78.6 V, VC = 103 V @ 5.8 A | Not rated for AEC-Q101; limited to commercial-grade industrial use | Select when space-constrained layouts require smaller SMD package and surge energy demand is ≤600 W |
| 1.5KE62A (ON Semiconductor) | Through-hole DO-201 package, same VBR/VC specs but higher RθJA (~100 °C/W), no AEC-Q101 option | Requires wave soldering; unsuitable for fully SMT automotive production | Choose only for legacy through-hole designs or prototyping where rework flexibility outweighs production efficiency |
Compared with SMBJ64A-E3/52T and 1.5KE62A, the 1.5SMC62AHM3_A/I uniquely combines AEC-Q101 qualification, 1500 W surge capacity in SMC form factor, and halogen-free compliance - making it the only drop-in solution for volume automotive SMT lines requiring zero layout change and full regulatory traceability.

FAQ
What is the clamping voltage of the 1.5SMC62AHM3_A/I under maximum surge conditions?
The 1.5SMC62AHM3_A/I clamps to a maximum of 85.0 V when subjected to its rated peak pulse current of 17.6 A (10/1000 µs waveform). This value is measured per standard test conditions in the Vishay datasheet (Document Number: 88303, Rev. 09-Mar-2026) and reflects worst-case device behavior at TA = 25 °C with recommended PCB pad layout. The 1.5SMC62AHM3_A/I maintains this clamping performance across its full operating temperature range.
Is the 1.5SMC62AHM3_A/I qualified for automotive applications?
Yes, the 1.5SMC62AHM3_A/I is AEC-Q101 qualified, as confirmed by the HM3 suffix and documentation in Vishay's 1.5SMC Series datasheet (Rev. 09-Mar-2026). It undergoes stress testing including temperature cycling, high-temperature reverse bias, and surge endurance per AEC-Q101-004 and AEC-Q101-007. The 1.5SMC62AHM3_A/I is approved for use in engine control units, body electronics, and ADAS modules where automotive-grade reliability is required.
What does the "HM3_A/I" suffix mean in 1.5SMC62AHM3_A/I?
The "HM3" denotes halogen-free, RoHS-compliant construction; "A" indicates AEC-Q101 qualification; and "I" specifies packaging in 13-inch tape-and-reel (3500 units per reel). This full suffix confirms the 1.5SMC62AHM3_A/I meets automotive environmental standards, contains no brominated flame retardants, and ships in high-volume SMT-ready format - distinct from commercial-grade M3 or E3 variants.
How does the 1.5SMC62AHM3_A/I compare to bidirectional TVS diodes like 1.5SMC62CA?
The 1.5SMC62AHM3_A/I is unidirectional and intended for DC line protection where polarity is fixed (e.g., +12 V rail to ground), offering lower leakage and tighter VBR tolerance than bidirectional equivalents. In contrast, 1.5SMC62CA protects AC or polarity-agnostic signals but exhibits higher reverse leakage and symmetric clamping. The 1.5SMC62AHM3_A/I cannot substitute for 1.5SMC62CA in AC-coupled applications due to its inherent polarity dependence.
What is the thermal resistance and maximum power dissipation of the 1.5SMC62AHM3_A/I?
The 1.5SMC62AHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per datasheet Fig. 2. Its steady-state power dissipation (PD) is rated at 6.5 W at TA = 50 °C. Derating applies above 50 °C ambient, and the 1.5SMC62AHM3_A/I must not exceed TJ = 150 °C under any operating condition.
