Product details
Overview
SMCJ60C-E3/9AT from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for clamping voltage transients on signal or power lines. It features a 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and 15.5 A peak pulse current (IPPM) at 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial systems.
For engineers reviewing the SMCJ60C-E3/9AT datasheet, SMCJ60C-E3/9AT pinout, SMCJ60C-E3/9AT application, or SMCJ60C-E3/9AT equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, 150 °C junction temperature rating, low incremental surge resistance, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ60C-E3/9AT operates as a bi-directional avalanche diode, symmetrically clamping both positive and negative transients without polarity marking. Its glass-passivated junction ensures stable breakdown behavior under repetitive surge conditions, and its thermal resistance (RθJA = 75 °C/W) supports operation up to 150 °C junction temperature when mounted per recommended pad layout.
It complies with ANSI/IEEE C62.35 for transient suppressor definitions and meets J-STD-020 MSL Level 1 (260 °C peak reflow). The device is RoHS-compliant (E3 suffix), qualified to AEC-Q101, and rated for 1000 µA maximum reverse leakage at 60 V stand-off - critical for low-power sensor line protection where leakage must not disrupt bias networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - maximum continuous reverse operating voltage before clamping begins; defines safe working range for protected circuitry. |
| VBR min/max | 66.7 V / 73.7 V at 1 mA - guaranteed avalanche onset window; ensures predictable turn-on across production lots. |
| VC @ IPPM | 96.8 V - clamped voltage at 15.5 A peak pulse; determines worst-case overvoltage seen by downstream components. |
| PPPM | 1500 W - peak pulse power handling with 10/1000 µs waveform; enables robust protection against IEC 61000-4-5 surge events. |
| ID @ VWM | 1.0 µA - reverse leakage at 60 V; low enough to avoid loading high-impedance sensor or reference lines. |
| TJ max | +150 °C - maximum junction temperature; supports under-hood automotive and industrial ambient environments. |
| Package | DO-214AB (SMCJ) - surface-mount, low-profile case with matte tin-plated leads; compatible with J-STD-002 solderability standards. |
Pinout & Package
DO-214AB (SMCJ) package: molded plastic case with J-bend leads, no polarity marking for bi-directional operation. Terminals are matte tin-plated and solderable per J-STD-002 and JESD 22-B102. Meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional avalanche junction | No functional distinction between terminals; either lead may connect to line or ground - enables flexible PCB routing for differential or single-ended protection. |
| Case (body) | Non-conductive thermal path | Plastic molding provides electrical isolation while allowing heat conduction via copper pad contact; requires minimum 8.0 mm × 8.0 mm pad per terminal for rated PPPM. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity bias, and surge endurance - suitable for engine control, ADAS, and body electronics. |
| Glass-passivated junction | Stable VBR tolerance and low leakage over lifetime; prevents parameter drift due to moisture ingress or contamination during reflow or field operation. |
| MSL Level 1 rating | Supports standard SMT reflow profiles up to 260 °C peak without preconditioning - eliminates moisture sensitivity handling requirements in manufacturing. |
| Low incremental surge resistance | Enables tighter VC/VBR ratio (96.8 V / 66.7 V ≈ 1.45); reduces clamping overshoot and improves protection margin for sensitive 3.3 V or 5 V logic interfaces. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CA-E3/52T | Lower PPPM (600 W), smaller SMB package (DO-214AA), same VWM/VBR range and bi-directionality. | Reduced surge handling; suited for space-constrained consumer ports but insufficient for industrial 1 kV/0.5 kA IEC 61000-4-5 Level 4. | Select only when board space is critical and surge threat level is limited to IEC 61000-4-2 ESD or low-energy transients. |
| 1.5KE60CA | Through-hole TO-218 package, same 60 V VWM and 1500 W PPPM, but higher RθJA (~30 °C/W) and no AEC-Q101 qualification. | Not suitable for automotive or high-reliability SMT production; requires wave soldering and larger board area. | Choose only for legacy through-hole designs or prototyping where reflow compatibility and automotive qualification are not required. |
Compared with SMBJ60CA-E3/52T and 1.5KE60CA, the SMCJ60C-E3/9AT uniquely combines 1500 W surge capacity, AEC-Q101 qualification, and SMT-ready DO-214AB packaging - making it the preferred choice for production automotive and industrial systems requiring validated reliability and automated assembly.

FAQ
What does the "C" suffix indicate in SMCJ60C-E3/9AT?
The "C" suffix in SMCJ60C-E3/9AT denotes bi-directional functionality - meaning the device clamps voltage transients equally in both polarities, with no cathode marking and symmetric electrical characteristics. This distinguishes it from uni-directional variants like SMCJ60A-E3/9AT, which require correct polarity orientation during placement. The SMCJ60C-E3/9AT is explicitly specified for bi-directional applications in Vishay's datasheet Document Number 88394.
Is SMCJ60C-E3/9AT qualified for automotive use?
Yes, SMCJ60C-E3/9AT is AEC-Q101 qualified per Vishay's ordering information and mechanical data tables. This qualification covers stress tests including temperature cycling, high-temperature operating life, and surge endurance - confirming suitability for automotive powertrain, chassis, and body electronics. The "E3" suffix further confirms RoHS compliance and JESD 201 Class 1A whisker resistance, supporting long-term reliability in automotive environments.
What is the maximum clamping voltage for SMCJ60C-E3/9AT under surge conditions?
The maximum clamping voltage (VC) for SMCJ60C-E3/9AT is 96.8 V at its rated peak pulse current (IPPM) of 15.5 A, measured with a 10/1000 µs waveform. This value is guaranteed across the operating temperature range and defines the upper voltage limit imposed on protected circuitry during transient events. It is derived directly from Vishay's Electrical Characteristics table on page 2 of document 88394.
How does the DO-214AB package of SMCJ60C-E3/9AT affect thermal performance?
The DO-214AB (SMCJ) package of SMCJ60C-E3/9AT 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 terminal. This thermal design enables the device to sustain its 1500 W peak pulse power rating without exceeding the 150 °C maximum junction temperature, provided PCB layout follows Vishay's recommended pad dimensions and copper weight. Smaller pads increase RθJA and reduce surge capability.
Can SMCJ60C-E3/9AT replace SMCJ60A-E3/9AT in an existing design?
No - SMCJ60C-E3/9AT cannot directly replace SMCJ60A-E3/9AT without circuit review, because the "C" variant is bi-directional while the "A" variant is uni-directional. Replacing a uni-directional TVS with a bi-directional one may cause unintended forward conduction or altered clamping behavior in DC-biased lines. The SMCJ60C-E3/9AT must be verified for polarity-insensitive placement and absence of steady-state reverse bias exceeding VWM in the target application.
