Product details
Overview
1.5SMC62CAHE3/9AT from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for robust ESD and surge 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 100 V at 17.6 A, and operates across –65 °C to +150 °C. It is widely deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5SMC62CAHE3/9AT datasheet, 1.5SMC62CAHE3/9AT pinout, 1.5SMC62CAHE3/9AT application, or 1.5SMC62CAHE3/9AT equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMC (DO-214AB) package compatibility, and compliance with IEC 61000-4-2/4-5 surge immunity requirements.
Technical Context
This device functions as a voltage-clamped shunt protector that activates during overvoltage transients-such as ESD events or inductive switching spikes-and diverts surge current away from sensitive downstream circuitry. Its bidirectional architecture enables symmetrical clamping on both polarities without polarity sensitivity.
It uses a glass-passivated silicon junction for stable breakdown behavior and low leakage (<1 µA at 53 V), with thermal resistance of 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-leads). The device is rated for repetitive 10/1000 µs surges at 0.01% duty cycle and meets MSL Level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 53.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working range. |
| VBR (Breakdown) | 68.9–75.1 V at 1 mA - Voltage at which device enters avalanche conduction; ensures precise, repeatable turn-on threshold. |
| VC (Clamping) | 100 V at 17.6 A - Peak voltage seen by protected circuit during 10/1000 µs surge; limits stress on downstream ICs. |
| PPPM | 1500 W - Peak pulse power handling capacity under standardized 10/1000 µs waveform; supports high-energy transients. |
| IR (Leakage) | <1 µA at 53 V - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss. |
| TJ max. | +150 °C - Maximum junction temperature rating enabling use in under-hood automotive and high-temperature industrial environments. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal (bidirectional) | One end of the symmetrical PN junction; no polarity marking required for bidirectional operation. |
| Cathode | Current exit terminal (bidirectional) | Opposite end of the symmetrical junction; identical electrical behavior to anode in bidirectional mode. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns. |
| 1500 W peak pulse power | Withstands high-energy lightning-induced surges (IEC 61000-4-5 Level 3/4) and inductive load switching spikes. |
| AEC-Q101 qualification | Validates suitability for automotive applications including engine control modules, ADAS sensors, and body electronics. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients, improving protection margin for 3.3 V/5 V logic. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and reflow at 260 °C peak, simplifying SMT assembly without baking requirements. |

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 PPPM (600 W), same VWM (55.1 V), SMB package (smaller footprint, higher RθJA). | Not AEC-Q101 qualified; suitable for commercial-grade consumer or computing applications only. | Select when board space is constrained and automotive qualification is not required. |
| 1.5KE68CA | Higher VWM (58.1 V), same bidirectional function, axial DO-201 package (through-hole, lower thermal performance). | Lacks MSL Level 1 rating and automated placement compatibility; used in legacy or high-reliability through-hole designs. | Choose for prototyping or repair where SMT infrastructure is unavailable, but expect reduced surge repetition capability. |
Compared with SMBJ64CA and 1.5KE68CA, the 1.5SMC62CAHE3/9AT delivers superior automotive-grade reliability, higher surge power headroom, and optimized SMT manufacturability-making it the preferred choice for volume production in harsh-environment electronics.

FAQ
What is the clamping voltage of the 1.5SMC62CAHE3/9AT at its rated peak pulse current?
The 1.5SMC62CAHE3/9AT clamps to a maximum of 100 V at its rated peak pulse current of 17.6 A under a 10/1000 µs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 8.0 mm × 8.0 mm copper pads) and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the 1.5SMC62CAHE3/9AT suitable for automotive applications?
Yes, the 1.5SMC62CAHE3/9AT is AEC-Q101 qualified and explicitly designated for automotive use via its "HE3" suffix. It has undergone stress testing for temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 Rev D, making it appropriate for engine control units, ADAS sensors, and infotainment system interfaces.
What does the "CA" suffix indicate in 1.5SMC62CAHE3/9AT?
The "CA" suffix in 1.5SMC62CAHE3/9AT denotes a bidirectional configuration-meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., "A"), it has no cathode band marking and functions identically in either polarity.
How does the 1.5SMC62CAHE3/9AT differ from the 1.5SMC62AHE3/9AT?
The 1.5SMC62CAHE3/9AT is bidirectional, whereas the 1.5SMC62AHE3/9AT is unidirectional. This results in different breakdown symmetry: the "CA" version clamps equally on both polarities with VBR = 68.9–75.1 V in each direction, while the "A" version has a defined cathode and conducts only in reverse bias, requiring correct PCB orientation.
What is the maximum operating temperature for the 1.5SMC62CAHE3/9AT?
The 1.5SMC62CAHE3/9AT has a maximum junction temperature (TJ max.) of +150 °C and an operating junction/storage temperature range of –65 °C to +150 °C. This wide thermal envelope supports deployment in under-hood automotive locations, industrial motor drives, and outdoor telecom enclosures without derating at ambient temperatures up to +125 °C.
