Product details
Overview
SMCJ60CA-E3/9AT from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features a 60 V standoff voltage (VWM), 96.8 V maximum clamping voltage at 15.5 A peak pulse current (10/1000 µs), and 1500 W peak pulse power dissipation - deployed in automotive sensor interfaces, industrial I/O protection, and telecom line surge suppression.
For engineers reviewing the SMCJ60CA-E3/9AT datasheet, SMCJ60CA-E3/9AT pinout, SMCJ60CA-E3/9AT application, or SMCJ60CA-E3/9AT equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification eligibility (via HE3 suffix variants), RoHS-compliant matte tin terminations, and thermal resistance (RθJA = 75 °C/W) under standard PCB pad layout.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, with breakdown voltage (VBR) specified at 66.7–73.7 V (min/max) at 1 mA test current. Its low incremental surge resistance enables rapid energy diversion during ESD or lightning-induced transients.
Clamping performance is validated per ANSI/IEEE C62.35 standards using a 10/1000 µs waveform; derating applies above TA = 25 °C per Fig. 2, and thermal impedance is characterized with 0.31" × 0.31" copper pads per terminal. No polarity marking is present on the SMCJ60CA-E3/9AT case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 60 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 66.7–73.7 V at 1 mA - Confirmed minimum/maximum threshold where device transitions into avalanche conduction. |
| VC (Clamping Voltage) | 96.8 V at IPPM = 15.5 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case transient event. |
| PPPM (Peak Pulse Power) | 1500 W - Maximum transient energy absorption capability under standardized surge waveform. |
| ID (Reverse Leakage) | 1.0 µA max at VWM - Ensures minimal standby power loss and signal integrity in high-impedance circuits. |
| TJ max | 150 °C - Maximum junction temperature defining operational reliability limit under sustained thermal stress. |
| RθJA | 75 °C/W - Thermal resistance from junction to ambient air on standard 8.0 mm × 8.0 mm copper pads; critical for thermal design margining. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile plastic case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. No polarity marking - bidirectional operation eliminates cathode/anode distinction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode / Cathode (bidirectional) | Either terminal serves as current entry point during positive or negative transient events; symmetrical conduction path. |
| Terminal 2 | Anode / Cathode (bidirectional) | Paired terminal completing the bidirectional clamp path; no functional distinction from Terminal 1 in layout or routing. |
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 | Supports robust immunity against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on 12 V/24 V systems. |
| MSL Level 1 (J-STD-020) | Allows unlimited floor life and reflow compatibility up to 260 °C peak, simplifying SMT manufacturing. |
| AEC-Q101 qualification option | HE3/HM3 variants meet automotive-grade reliability requirements for engine control, ADAS sensors, and infotainment. |
| UL 94 V-0 molding compound | Ensures flame-retardant housing for safety-critical industrial and telecom equipment compliance. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CA-E3/52T | Lower PPPM (600 W), smaller SMB (DO-214AA) package, same VWM/VBR/VC specs. | Suitable for space-constrained consumer boards but not for industrial 1500 W surge requirements. | Select when board area is limited and peak surge energy does not exceed 600 W. |
| SMCJ60A-E3/9AT | Unidirectional variant; identical VWM/VBR/VC/PPPM but requires polarity-aware placement and adds series diode for AC lines. | Used where DC bias exists and reverse conduction must be blocked (e.g., power rail clamping). | Choose only if circuit topology mandates unidirectional blocking; otherwise SMCJ60CA-E3/9AT offers simpler layout. |
Compared with SMBJ60CA-E3/52T and SMCJ60A-E3/9AT, the SMCJ60CA-E3/9AT uniquely delivers 1500 W bidirectional clamping in the SMC footprint - enabling higher-energy surge handling without polarity constraints or package downsizing trade-offs.

FAQ
What is the clamping voltage of the SMCJ60CA-E3/9AT under a 10/1000 µs surge?
The SMCJ60CA-E3/9AT has a maximum clamping voltage (VC) of 96.8 V at 15.5 A peak pulse current with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and reflects the highest voltage imposed on the protected circuit during standardized surge testing. The SMCJ60CA-E3/9AT maintains this clamping performance across its full operating temperature range when mounted per recommended pad layout.
Is the SMCJ60CA-E3/9AT suitable for automotive applications?
The SMCJ60CA-E3/9AT itself is commercial-grade (E3 suffix), but Vishay offers AEC-Q101 qualified versions under HE3/HM3 suffixes (e.g., SMCJ60CAHE3_A/I). While the SMCJ60CA-E3/9AT shares identical electrical characteristics and package, formal automotive qualification requires the HE3 variant. For non-safety-critical automotive subsystems with internal validation, the SMCJ60CA-E3/9AT may be used - however, the SMCJ60CA-E3/9AT is not certified to AEC-Q101.
How does the SMCJ60CA-E3/9AT differ from the unidirectional SMCJ60A-E3/9AT?
The SMCJ60CA-E3/9AT is bidirectional with no polarity marking and symmetrical clamping in both voltage polarities, whereas the SMCJ60A-E3/9AT is unidirectional with a cathode band and blocks reverse current. Both share identical VWM (60 V), VBR (66.7–73.7 V), VC (96.8 V), and PPPM (1500 W), but the SMCJ60CA-E3/9AT eliminates orientation sensitivity during placement - making it preferable for AC-coupled or floating signal paths where polarity is undefined.
What is the thermal resistance of the SMCJ60CA-E3/9AT, and how is it measured?
The SMCJ60CA-E3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W, measured with the device mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal on FR-4 PCB. This value assumes still air conditions and defines the temperature rise per watt of steady-state power dissipation. For accurate thermal design, the SMCJ60CA-E3/9AT must be applied within derated power limits above TA = 25 °C per Figure 2 in the datasheet.
Does the SMCJ60CA-E3/9AT require a heatsink for normal operation?
No, the SMCJ60CA-E3/9AT does not require an external heatsink under normal transient suppression duty cycles, as its 6.5 W steady-state power dissipation rating (PD) is intended for continuous operation on standard PCB copper. Heatsinking is unnecessary because TVS devices operate in short-duration avalanche mode - the 1500 W PPPM rating applies only to sub-millisecond pulses. However, PCB layout must follow Vishay's recommended 8.0 mm × 8.0 mm pad dimensions to ensure specified RθJA and surge reliability for the SMCJ60CA-E3/9AT.
