Overview
1.5SMC62AHE3/9AT from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge clamping with 1500 W peak pulse power (10/1000 μs), 62 V breakdown voltage (min 58.9 V, max 65.1 V at 1 mA), and 85 V maximum clamping voltage at 17.6 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the 1.5SMC62AHE3/9AT datasheet, 1.5SMC62AHE3/9AT pinout, 1.5SMC62AHE3/9AT application, or 1.5SMC62AHE3/9AT equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 53.0 V stand-off voltage, <1.0 μA reverse leakage at VWM, and thermal resistance of 75 °C/W junction-to-ambient - critical for board-level ESD and lightning transient protection design.
Technical Context
The 1.5SMC62AHE3/9AT employs a glass-passivated silicon junction optimized for fast response to transients (<1.0 ns), low incremental surge resistance, and stable clamping under repetitive 0.01% duty cycle pulses. Its unidirectional configuration provides cathode-banded polarity identification and forward conduction capability up to 200 A (8.3 ms half-sine).
Rated for -65 °C to +150 °C operating junction temperature and compliant with J-STD-020 MSL Level 1 (260 °C peak reflow), it supports automated SMT placement on standard 8.0 mm × 8.0 mm copper pads per terminal. The device meets UL 497B recognition (QVGQ2) and is halogen-free RoHS-compliant per Vishay's HM3/HE3 grading.

Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters for smart home hubs, guarding against transformer regulation failure. IC Role / Device Role / Timing Role: Standoff-rated TVS across DC output (e.g., 5 V or 12 V) to clamp fault conditions before USB-C PD controller or load. Use Value: 53.0 V VWM allows safe operation under normal 60 V max adapter output; 1500 W rating absorbs sustained overvoltage events. |
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 | Lower peak power (600 W), SMB package (smaller footprint), 64 V VBR, higher RθJA (100 °C/W) | Best suited for space-constrained consumer PCBs where surge energy is limited to <600 W | Select when board area is critical and full 1500 W clamping is not required; verify thermal margin with reduced copper pad area |
| 1.5KE62A-T | Through-hole DO-201 package, same VBR/VC, but lower surge repetition capability and no AEC-Q101 qualification | Used in legacy industrial power supplies where manual assembly or high-reliability through-hole mounting is preferred | Choose only for non-automotive, non-SMT designs; avoid where AEC-Q101 compliance or automated placement is mandatory |
Compared with SMBJ64A-E3/52T and 1.5KE62A-T, the 1.5SMC62AHE3/9AT delivers superior surge robustness (1500 W vs. 600 W or 1500 W with inferior thermal performance), automotive qualification, and SMT scalability - making it the optimal choice for next-generation automotive and industrial modules requiring validated reliability and high-density layout.

FAQ
What is the clamping voltage of the 1.5SMC62AHE3/9AT at its rated peak pulse current?
The 1.5SMC62AHE3/9AT has a maximum clamping voltage (VC) of 85.0 V when subjected to its rated 17.6 A peak pulse current (IPPM) under the standard 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 worst-case surge events. Designers use this parameter to ensure downstream components remain within their absolute maximum voltage ratings.
Is the 1.5SMC62AHE3/9AT suitable for automotive applications?
Yes, the 1.5SMC62AHE3/9AT is AEC-Q101 qualified, as confirmed by its "HE3" suffix and documentation in Vishay's 1.5SMC series datasheet (Rev. 09-Mar-2026). It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and surge endurance - making it approved for use in engine control units, body electronics, and ADAS modules where reliability under thermal and electrical stress is mandatory.
What does the "9AT" suffix indicate in 1.5SMC62AHE3/9AT?
The "9AT" suffix in 1.5SMC62AHE3/9AT specifies the packaging format: 13-inch diameter plastic tape-and-reel with 3500 units per reel. This differs from "57T" (7-inch reel, 850 units) and aligns with high-volume SMT production requirements. The "HE3" portion confirms RoHS-compliant, AEC-Q101-qualified construction with matte tin plating and J-STD-020 MSL Level 1 rating.
How does the 1.5SMC62AHE3/9AT compare to bidirectional TVS diodes like 1.5SMC62CAHE3/9AT?
The 1.5SMC62AHE3/9AT is unidirectional and features a cathode band for polarity-sensitive placement, enabling forward conduction and protection against positive-only transients. In contrast, 1.5SMC62CAHE3/9AT is bidirectional with symmetric clamping in both directions and no polarity marking. Use the unidirectional 1.5SMC62AHE3/9AT on DC power rails or single-ended signal lines; choose the CA version only for AC-coupled or differential lines requiring symmetrical surge handling.
What is the thermal resistance of the 1.5SMC62AHE3/9AT, and how does it affect layout?
The 1.5SMC62AHE3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. To maintain safe junction temperatures below 150 °C during repetitive surges, PCB layout must provide adequate copper area and thermal vias - especially critical in automotive under-hood applications where ambient temperatures exceed 85 °C.
