Product details
Overview
1.5SMC62CAHM3/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 62 V standoff voltage (VWM), 68.9–75.1 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (10/1000 μs), clamping voltage of 102 V at 17.6 A, and operates across –65 °C to +150 °C. It is used to protect automotive sensor interfaces and industrial I/O circuits against ESD, lightning surges, and inductive switching transients.
For engineers reviewing the 1.5SMC62CAHM3/I datasheet, 1.5SMC62CAHM3/I pinout, 1.5SMC62CAHM3/I application, or 1.5SMC62CAHM3/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMC (DO-214AB) package compatibility, and verified 102 V clamping performance under 17.6 A surge current.
Technical Context
The 1.5SMC62CAHM3/I is a glass-passivated, surface-mount TVS diode optimized for fast response (<1 ns) and low clamping ratio (VC/VBR ≈ 1.43). Its bidirectional architecture enables symmetrical suppression of positive and negative transients without polarity sensitivity-critical for AC-coupled or differential signal lines.
It delivers 1500 W peak pulse power per the standardized 10/1000 μs waveform, with thermal resistance of 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-leads), enabling reliable operation on standard 8 mm × 8 mm copper pads. The HM3 suffix confirms halogen-free, RoHS-compliant, and AEC-Q101 qualified construction for automotive-grade reliability.

IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed between signal line and ground to shunt transients before reaching downstream ADC or microcontroller input. Use Value: Maintains signal integrity by limiting transient voltage to ≤102 V, preventing latch-up or damage to 3.3 V/5 V interface ICs rated for ≤120 V absolute maximum. |
Use Scenario: Safeguarding 24 V DC digital inputs on programmable logic controllers exposed to relay coil flyback and field wiring surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on input terminal block, operating in parallel with optocoupler input stage. Use Value: Withstands repetitive 1500 W surges while maintaining <1 μA leakage at 62 V, ensuring stable logic thresholds and eliminating false triggering. |
| Telecom Line Interface Protection | Motor Drive Gate Driver Protection |
Use Scenario: Shielding RS-485 transceiver bus lines in outdoor base stations from lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Bidirectional TVS connected line-to-line and line-to-ground to suppress differential and common-mode transients simultaneously. Use Value: Symmetrical 62 V standoff and 102 V clamping enable balanced protection without skewing differential signaling margins. |
Use Scenario: Protecting high-side/low-side gate driver supply rails (e.g., bootstrap circuits) in BLDC inverters from Miller-induced spikes and shoot-through transients. IC Role / Device Role / Timing Role: Clamp placed across VDD and GND pins of gate driver IC to limit supply rail excursions during fast switching. Use Value: Fast <1 ns response and low incremental surge resistance prevent voltage overshoot beyond 102 V, avoiding driver IC overvoltage shutdown or latch-up. |
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 VWM, SMB package (smaller footprint, higher RθJA = 85 °C/W). | Suitable for lower-energy transients (IEC 61000-4-2 ESD only); not recommended for ISO 7637-2 or IEC 61000-4-5. | Select when board space is constrained and surge energy is limited to ≤600 W. |
| 1.5KE62CA | Through-hole DO-201 package, identical electrical specs (62 V VWM, 1500 W), but incompatible with SMT assembly. | Used in legacy or high-reliability through-hole designs; lacks AEC-Q101 qualification in standard variants. | Choose only for manual assembly or retrofit where SMT is unavailable; verify HM3-level automotive compliance separately. |
Compared with SMBJ64CA and 1.5KE62CA, the 1.5SMC62CAHM3/I uniquely combines AEC-Q101 qualification, SMC surface-mount compatibility, and full 1500 W surge rating-making it the preferred choice for new automotive and industrial SMT designs requiring production-ready reliability.

FAQ
What is the clamping voltage of the 1.5SMC62CAHM3/I under a 10/1000 μs surge?
The 1.5SMC62CAHM3/I has a maximum clamping voltage (VC) of 102 V at 17.6 A peak pulse current, measured per the standardized 10/1000 μs waveform. This value is guaranteed across its operating temperature range and forms the basis for system-level overvoltage margin design. The 1.5SMC62CAHM3/I maintains this clamping performance with minimal derating up to +125 °C junction temperature.
Is the 1.5SMC62CAHM3/I suitable for automotive applications?
Yes-the 1.5SMC62CAHM3/I carries the HM3 suffix, confirming it is halogen-free, RoHS-compliant, and fully AEC-Q101 qualified. It has passed stress tests including temperature cycling, high-temperature operating life, and ESD per JESD22 standards. The 1.5SMC62CAHM3/I is approved for use in engine control units, body electronics, and ADAS sensor modules where transient immunity and long-term reliability are mandatory.
What does the "CA" suffix indicate in 1.5SMC62CAHM3/I?
The "CA" suffix in 1.5SMC62CAHM3/I denotes a bidirectional configuration-meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., "A"), the 1.5SMC62CAHM3/I has no cathode band marking and functions identically regardless of terminal orientation, simplifying layout for AC-coupled or differential signal paths.
What is the thermal resistance of the 1.5SMC62CAHM3/I?
The 1.5SMC62CAHM3/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 JEDEC standards, and a junction-to-leads resistance (RθJL) of 15 °C/W. These values enable accurate thermal modeling for power dissipation in continuous and pulsed operation-especially important when designing for repeated surge events in industrial controls.
How does the 1.5SMC62CAHM3/I differ from the 1.5SMC62A variant?
The 1.5SMC62CAHM3/I is bidirectional and AEC-Q101 qualified with halogen-free construction (HM3), whereas the base 1.5SMC62A is unidirectional, commercial-grade, and lacks automotive qualification. The 1.5SMC62CAHM3/I also features tighter VBR tolerance (68.9–75.1 V vs. 68.9–75.1 V for CA, but unidirectional A has different test conditions) and enhanced MSL Level 1 reflow robustness. Functionally, only the 1.5SMC62CAHM3/I supports symmetrical clamping required for RS-485 or CAN bus protection.
