Product details
Overview
1.5SMC62AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge 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 motor drives, and telecom interface protection.
For engineers reviewing the 1.5SMC62AHM3/H datasheet, 1.5SMC62AHM3/H pinout, 1.5SMC62AHM3/H application, or 1.5SMC62AHM3/H equivalent, this part delivers AEC-Q101 qualified transient suppression in SMC (DO-214AB) package with halogen-free RoHS compliance, low incremental surge resistance, and fast response time critical for IEC 61000-4-5 Level 4-compliant designs.
Technical Context
The 1.5SMC62AHM3/H operates as a unidirectional avalanche diode, clamping transients above its reverse stand-off voltage (53.0 V) by entering avalanche breakdown. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<1.0 µA at VWM), while thermal resistance (RθJA = 75 °C/W) supports operation up to 150 °C junction temperature under defined pad layout.
Designed for repetitive surge events at 0.01% duty cycle, it sustains 17.6 A peak pulse current (IPPM) with 85.0 V clamping, delivering <1 ns response time and meeting UL 497B recognition. The cathode-band polarity marking enables unambiguous PCB orientation during automated placement on 8.0 mm × 8.0 mm copper pads.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60A | Lower PPPM (400 W), higher VC/VBR ratio (1.43), SMA package (smaller thermal mass) | Limited to lower-energy surges (IEC 61000-4-2 ESD only); not rated for ISO 7637-2 load dump | Select when board space is constrained and surge energy remains below 400 W; verify thermal derating at 75 °C ambient. |
| 1.5KE62A | Through-hole DO-201 package, identical VBR/VC specs but 20% higher RθJA (90 °C/W) | Requires wave soldering or hand assembly; unsuitable for high-density SMT production | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with SMAJ60A and 1.5KE62A, the 1.5SMC62AHM3/H uniquely combines AEC-Q101 qualification, halogen-free compliance, 1500 W surge capacity, and SMC package thermal performance - making it the preferred choice for volume automotive and industrial SMT production requiring long-term supply stability and regulatory alignment.

FAQ
What is the clamping voltage of the 1.5SMC62AHM3/H under a 10/1000 µs surge?
The 1.5SMC62AHM3/H exhibits a maximum clamping voltage (VC) of 85.0 V when subjected to its rated peak pulse current of 17.6 A with a 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88303 and represents the upper limit of voltage imposed on the protected circuit during standardized surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the 1.5SMC62AHM3/H suitable for automotive applications?
Yes, the 1.5SMC62AHM3/H is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's 1.5SMC series datasheet (Rev. 09-Mar-2026). It meets stress tests including high-temperature reverse bias, temperature cycling, and mechanical shock - making it appropriate for under-hood engine control modules, body electronics, and ADAS power domains where sustained 150 °C operation and surge immunity are required.
What does the "HM3" suffix indicate in 1.5SMC62AHM3/H?
The "HM3" suffix in 1.5SMC62AHM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Per Vishay's ordering information table, HM3 devices use bromine-free flame retardants in the molding compound and meet JESD201 Class 2 whisker resistance - distinguishing them from M3 (halogen-free, commercial grade) and HE3 (RoHS-compliant, AEC-Q101) variants.
How does the 1.5SMC62AHM3/H compare to bidirectional TVS diodes like 1.5SMC62CA?
The 1.5SMC62AHM3/H is unidirectional and intended for DC line protection where polarity is fixed (e.g., +12 V rail to ground), offering lower leakage (<1.0 µA) and tighter VBR tolerance. In contrast, 1.5SMC62CA is bidirectional and suited for AC or differential lines (e.g., RS-485), but exhibits double the leakage at VWM. The 1.5SMC62AHM3/H cannot substitute for 1.5SMC62CA in AC-coupled applications without circuit redesign.
What PCB pad layout is recommended for optimal thermal performance of the 1.5SMC62AHM3/H?
Vishay specifies mounting the 1.5SMC62AHM3/H on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal to achieve rated 1500 W pulse power and 75 °C/W thermal resistance. Reducing pad area increases junction temperature rise during surge events and may cause premature failure; thermal vias to inner ground planes are recommended for sustained high-temperature operation.
