Product details
Overview
1.5SMC62CAHE3_A/H 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 breakdown voltage (VBR min/max: 58.9–65.1 V), 1500 W peak pulse power (10/1000 µs), clamping voltage of 85.0 V at 17.6 A, and operates across –65 °C to +150 °C. It is used to protect automotive sensor interfaces, industrial I/O ports, and telecom line cards against ESD, lightning surges, and inductive switching transients.
For engineers reviewing the 1.5SMC62CAHE3_A/H datasheet, 1.5SMC62CAHE3_A/H pinout, 1.5SMC62CAHE3_A/H application, or 1.5SMC62CAHE3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMC (DO-214AB) package compatibility, and verified 85.0 V clamping performance under 10/1000 µs surge conditions.
Technical Context
This device is a glass-passivated, surface-mount TVS diode optimized for fast response (<1 ps) and low incremental surge resistance. Its bidirectional architecture enables symmetrical clamping in AC-coupled or floating signal paths without polarity constraints.
It delivers 1500 W peak pulse power per the 10/1000 µs waveform standard, with thermal resistance RθJA = 75 °C/W and RθJL = 15 °C/W, enabling reliable operation on standard 8.0 mm × 8.0 mm copper pads. The AEC-Q101 qualification confirms suitability for automotive electronics under harsh thermal and vibration conditions.
Key Specifications

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) | Not suitable for 1500 W surge environments; limited to lower-energy IEC 61000-4-2 ESD or low-duty-cycle transients | Select when board space is constrained and surge threat level is ≤600 W; verify thermal margin with RθJA = 100 °C/W |
| 1.5KE62CA | Through-hole DO-201 package, identical 62 V VBR and 1500 W rating, but no AEC-Q101 qualification | Lacks automotive qualification; not recommended for production automotive ECUs or safety-critical systems | Use only in commercial/industrial applications where AEC-Q101 is not mandated and through-hole assembly is preferred |
Compared with SMBJ64CA and 1.5KE62CA, the 1.5SMC62CAHE3_A/H uniquely combines AEC-Q101 qualification, SMC surface-mount compatibility, and full 1500 W surge handling-making it the only option qualified for automotive front-end protection without layout or reliability compromise.

FAQ
What does the "CA" suffix mean in 1.5SMC62CAHE3_A/H?
The "CA" suffix in 1.5SMC62CAHE3_A/H denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression in both polarities. Unlike unidirectional variants (e.g., 1.5SMC62A), it has no cathode marking and functions identically regardless of voltage polarity-ideal for AC lines, differential signals, and floating grounds. This is confirmed in Vishay's 1.5SMC datasheet section "DEVICES FOR BIDIRECTION APPLICATIONS".
Is 1.5SMC62CAHE3_A/H qualified for automotive use?
Yes, 1.5SMC62CAHE3_A/H is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet under "FEATURES" and "ORDERING INFORMATION". The "HE3" suffix indicates RoHS-compliant and AEC-Q101 qualified construction, validated for temperature cycling, humidity, mechanical shock, and other stress tests required for automotive electronic modules.
What is the clamping voltage of 1.5SMC62CAHE3_A/H at its rated peak pulse current?
The clamping voltage (VC) of 1.5SMC62CAHE3_A/H is 85.0 V at 17.6 A, measured under the standardized 10/1000 µs double-exponential surge waveform. This value is specified in the "ELECTRICAL CHARACTERISTICS" table of the Vishay 1.5SMC datasheet (Document Number: 88303), ensuring predictable overvoltage limiting during worst-case transient events.
How does the SMC (DO-214AB) package of 1.5SMC62CAHE3_A/H compare thermally to smaller packages like SMB?
The SMC (DO-214AB) package of 1.5SMC62CAHE3_A/H offers RθJA = 75 °C/W and RθJL = 15 °C/W, significantly better than SMB's typical RθJA ≈ 100 °C/W. This allows sustained 1500 W surge dissipation with less junction temperature rise-critical for automotive and industrial applications where ambient temperatures exceed 85 °C and board copper area is limited.
Can 1.5SMC62CAHE3_A/H replace a unidirectional TVS like 1.5SMC62A in an existing design?
No-1.5SMC62CAHE3_A/H is bidirectional and lacks polarity marking, while 1.5SMC62A is unidirectional with a cathode band. Substitution requires verifying circuit topology: bidirectional use is mandatory for AC-coupled or floating nodes; unidirectional devices are required for DC-biased lines where reverse leakage must be minimized below 1 µA at VWM. Direct replacement may cause unintended conduction in DC paths.
