Product details
Overview
1.5SMC62CAHM3_A/H from Vishay General Semiconductor is a bidirectional 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 min/max = 58.9–65.1 V), 1500 W peak pulse power (10/1000 µs), and clamps transients to ≤85.0 V at 17.6 A, making it suitable for automotive sensor interface and industrial I/O line protection.
For engineers reviewing the 1.5SMC62CAHM3_A/H datasheet, 1.5SMC62CAHM3_A/H pinout, 1.5SMC62CAHM3_A/H application, or 1.5SMC62CAHM3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMC (DO-214AB) package compatibility, and compliance with UL 497B surge protector requirements.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 µA leakage at 53.0 V), but conducts heavily when reverse voltage exceeds its breakdown threshold, diverting surge current away from downstream circuitry. Its glass-passivated junction ensures stable avalanche characteristics and low incremental surge resistance.
Designed for repetitive transient suppression, it supports 0.01% duty cycle at 1500 W with thermal derating above 25 °C (RθJA = 75 °C/W). The bidirectional configuration eliminates polarity concerns in AC-coupled or differential signal paths, and its MSL Level 1 rating enables standard reflow assembly without moisture sensitivity concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V - Ensures reliable turn-on before protected ICs exceed absolute maximum ratings |
| VWM | 53.0 V - Maximum continuous working voltage; defines safe operating margin below breakdown |
| VC @ IPPM | 85.0 V @ 17.6 A - Clamping voltage during 1500 W surge; determines worst-case stress on downstream components |
| PPPM | 1500 W - Peak pulse power handling per 10/1000 µs waveform; validates protection against lightning & inductive spikes |
| IPPM | 17.6 A - Corresponding peak pulse current; used to size PCB trace width and verify layout survivability |
| TJ max | +150 °C - Junction temperature limit; enables operation in under-hood automotive environments |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 8.0 mm × 8.0 mm copper pad requirement for thermal performance |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads; meets UL 94 V-0 flammability rating and J-STD-002 solderability standards. Polarity marking: none for bidirectional types.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward conduction mode | Not functional in TVS clamping operation; bidirectional symmetry means either terminal serves as cathode/anode depending on transient polarity |
| Cathode | Current exit terminal in forward conduction mode | Identical electrical role to Anode due to bidirectional construction; no band marking required |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JEDEC standards |
| 1500 W peak pulse power | Withstands IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on 50 Ω source impedance without degradation |
| Low clamping ratio (VC/VBR ≈ 1.31) | Minimizes let-through voltage during clamping-critical for protecting 60 V-rated MOSFETs and CAN transceivers |
| Halogen-free & RoHS-compliant | Meets EU Directive 2011/65/EU and JESD201 Class 2 whisker resistance for long-term solder joint integrity |
| MSL Level 1 | Allows unlimited floor life and standard reflow profile (peak 260 °C) without baking preconditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Lower peak power (600 W), same VBR range (60.8–67.2 V), SMB package (smaller footprint, higher RθJA) | Less robust for high-energy lightning surges; suited for space-constrained consumer electronics | Select when board area is critical and surge threat level is limited to IEC 61000-4-4 EFT only |
| 1.5KE62CA | Higher PPPM (1500 W), axial-leaded DO-201 package, slower response due to lead inductance | Not SMT-compatible; requires through-hole assembly and larger board real estate | Choose only for legacy designs or prototyping where reflow compatibility is not required |
Compared with SMBJ64CA and 1.5KE62CA, the 1.5SMC62CAHM3_A/H delivers optimal balance of high-energy surge handling, SMT manufacturability, and automotive qualification-making it the preferred choice for new production designs requiring AEC-Q101 compliance and DO-214AB thermal performance.

FAQ
What is the breakdown voltage tolerance for 1.5SMC62CAHM3_A/H?
The 1.5SMC62CAHM3_A/H has a specified breakdown voltage range of 58.9 V to 65.1 V at 1.0 mA test current (VBR min/max), corresponding to a ±5% tolerance around the nominal 62 V rating. This tight distribution ensures consistent clamping behavior across production lots and supports reliable system-level surge margin calculations.
Is 1.5SMC62CAHM3_A/H suitable for automotive applications?
Yes, the 1.5SMC62CAHM3_A/H carries the HM3 suffix indicating halogen-free, RoHS-compliant, and AEC-Q101 qualified construction. It has passed stress tests including high-temperature reverse bias, temperature cycling, and mechanical shock-meeting requirements for engine control units, body electronics, and ADAS sensor modules.
What does the "CA" suffix mean in 1.5SMC62CAHM3_A/H?
The "CA" suffix denotes a bidirectional configuration: the 1.5SMC62CAHM3_A/H functions identically in both polarities, with symmetrical breakdown and clamping characteristics. Unlike unidirectional variants (e.g., 1.5SMC62AHM3_A/H), it requires no polarity marking and is ideal for AC signal lines or differential buses like CAN or RS-485.
How is thermal performance defined for 1.5SMC62CAHM3_A/H?
Thermal performance is characterized by RθJA = 75 °C/W (junction-to-ambient, mounted on 8.0 mm × 8.0 mm copper pads) and RθJL = 15 °C/W (junction-to-leads). These values enable accurate junction temperature estimation during surge events and confirm suitability for operation up to +150 °C ambient when properly laid out per Vishay's recommended pad dimensions.
Does 1.5SMC62CAHM3_A/H meet UL recognition requirements?
Yes, the 1.5SMC62CAHM3_A/H is recognized by Underwriters Laboratories under file E136766 for both unidirectional and bidirectional devices, compliant with UL 497B for signal and power circuit protectors. This certification validates its use in end-equipment requiring UL listing, including industrial controls and telecom infrastructure.
