Product details
Overview
1.5SMC62CAHM3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, rated for 1500 W peak pulse power (10/1000 μs), 62 V breakdown voltage (min 58.9 V, max 65.1 V at 1 mA), and clamping voltage of 85.0 V at 17.6 A. It protects signal lines and power rails in automotive sensor units and industrial control interfaces against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1.5SMC62CAHM3_A/I datasheet, 1.5SMC62CAHM3_A/I pinout, 1.5SMC62CAHM3_A/I application, or 1.5SMC62CAHM3_A/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), clamping performance under standardized surge waveforms, and direct alternatives with documented voltage and power trade-offs.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR, VWM, and VC specifications in forward and reverse directions. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for protecting high-speed analog inputs and CAN bus receivers.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads, it meets J-STD-020 MSL Level 1 (peak reflow 260 °C) and supports repetitive surge duty cycles up to 0.01 %. The HM3 suffix confirms halogen-free, RoHS-compliant construction with AEC-Q101 qualification for automotive-grade reliability.

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 64 V nominal VBR, SMB package (smaller footprint, higher RθJA) | Suitable for space-constrained consumer electronics but not automotive-level surge immunity | Select when board area is critical and surge threat level is limited to IEC 61000-4-2 contact discharge only |
| 1.5KE62CA | Same VBR and PPPM, but axial DO-201 package (through-hole, higher inductance, manual assembly) | Used in legacy industrial power supplies where automated SMT is unavailable or thermal mass requirement exceeds SMC capability | Choose only if existing through-hole assembly infrastructure exists and board-level EMI filtering compensates for higher lead inductance |
Compared with 1.5SMC62CAHM3_A/I, SMBJ64CA offers reduced board area at the expense of 60 % lower surge energy handling, while 1.5KE62CA provides identical electrical protection in a less manufacturable form factor requiring manual soldering and delivering inferior high-frequency clamping due to lead inductance.

FAQ
What does the "HM3" suffix mean in 1.5SMC62CAHM3_A/I?
The HM3 suffix in 1.5SMC62CAHM3_A/I indicates halogen-free, RoHS-compliant construction with full AEC-Q101 qualification for automotive applications. It also specifies tape-and-reel packaging in 13-inch reels (I-type carrier), distinguishing it from commercial-grade M3 or E3 variants lacking automotive certification.
Is 1.5SMC62CAHM3_A/I suitable for protecting CAN FD bus lines?
Yes, 1.5SMC62CAHM3_A/I is suitable for CAN FD protection due to its bidirectional symmetry, low clamping voltage (85.0 V), and fast response time. Its 53.0 V stand-off voltage provides adequate margin above CAN FD's ±40 V common-mode range, and its 1500 W rating handles ISO 11898-2 specified surge levels when used with appropriate series impedance.
How does the clamping voltage of 1.5SMC62CAHM3_A/I compare to its breakdown voltage?
The clamping voltage of 1.5SMC62CAHM3_A/I is 85.0 V at 17.6 A, which is approximately 1.34× its minimum breakdown voltage (58.9 V). This clamping ratio reflects low incremental surge resistance and ensures protected circuits experience minimal overvoltage during standardized 10/1000 μs transients.
Can 1.5SMC62CAHM3_A/I be used in place of a unidirectional TVS like 1.5SMC62AHM3_A/I?
No - 1.5SMC62CAHM3_A/I is bidirectional and lacks polarity marking, whereas 1.5SMC62AHM3_A/I is unidirectional with cathode band identification. Substituting them requires verifying circuit topology: bidirectional use is mandatory for AC-coupled or floating lines, while unidirectional types are required for DC-biased rails where reverse conduction must be blocked.
What is the maximum PCB copper pad size needed to achieve the full 1500 W rating for 1.5SMC62CAHM3_A/I?
To achieve the full 1500 W peak pulse power rating, 1.5SMC62CAHM3_A/I requires mounting on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, as specified in the Vishay datasheet. Smaller pads increase thermal resistance and require derating per Figure 2 in document 88303.
