Product details
Overview
SMCJ60C-E3/57T from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection of sensitive electronics. It features a 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and clamps transients to ≤96.8 V at 15.5 A, commonly used on automotive sensor signal lines and industrial I/O interfaces.
For engineers reviewing the SMCJ60C-E3/57T datasheet, SMCJ60C-E3/57T pinout, SMCJ60C-E3/57T application, or SMCJ60C-E3/57T equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, 1500 W surge rating with 10/1000 µs waveform, low incremental surge resistance, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ60C-E3/57T operates as a bi-directional avalanche diode, symmetrically clamping voltage surges above its breakdown threshold in both polarities. Its glass-passivated junction ensures stable VBR tolerance (±5%) and fast response time (<1 ns), while the DO-214AB package provides low thermal resistance (RθJL = 15 °C/W) and meets UL 94 V-0 flammability rating.
Designed for transient suppression per ANSI/IEEE C62.35, it handles non-repetitive 10/1000 µs surges up to 15.5 A and withstands operating junction temperatures from –55 °C to +150 °C. The device is rated for 1000 µA maximum reverse leakage at 60 V and exhibits no polarity marking due to bi-directional symmetry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse working voltage before clamping begins |
| VBR min/max | 66.7 V / 73.7 V - Breakdown occurs within this range at 1 mA test current, defining turn-on threshold |
| VC @ IPPM | ≤96.8 V - Clamped voltage at 15.5 A peak pulse current, limiting stress on downstream ICs |
| PPPM | 1500 W - Peak surge power handling capability with 10/1000 µs waveform |
| ID @ VWM | ≤1000 µA - Low leakage ensures minimal standby power loss and signal integrity |
| TJ max | +150 °C - Enables operation in under-hood automotive and high-temperature industrial environments |
| MSL Level | Level 1 (J-STD-020) - Supports standard reflow without moisture sensitivity concerns |
Pinout & Package
SMCJ60C-E3/57T uses the DO-214AB (SMCJ) surface-mount package: low-profile, molded epoxy case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; no polarity marking due to bi-directional symmetry.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Case (body) | Thermal and mechanical interface | DO-214AB body transfers heat to PCB copper pads; requires 8.0 mm × 8.0 mm pad area per terminal for rated PPPM |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, ADAS sensors, and infotainment power rails |
| Glass-passivated junction | Ensures stable VBR over temperature and lifetime, with reduced parameter drift vs. epoxy-passivated alternatives |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients, improving clamping precision for 3.3 V/5 V logic protection |
| MSL Level 1, 260 °C peak reflow | Enables single-pass lead-free reflow without baking or special handling |
| UL 94 V-0 compliant molding compound | Meets flame-retardancy requirements for industrial and transportation end equipment |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ESD events in vehicle ECUs. IC Role / Device Role / Timing Role: Bi-directional clamping element placed directly at connector entry point to shunt transients before reaching signal conditioning circuitry. Use Value: Withstands 1500 W surges and maintains ≤96.8 V clamping, preserving integrity of 5 V rail and 12-bit ADC front-ends in harsh automotive environments. | Use Scenario: Safeguarding digital input modules in programmable logic controllers against inductive kickback from solenoid/relay switching. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 24 V DC input channels, positioned between field wiring and optocoupler isolation barrier. Use Value: Fast <1 ns response and low leakage (<1000 µA) prevent false triggering while enabling reliable detection of true 24 V logic states. |
| Telecom Line Interface | Consumer Power Adapter Output |
Use Scenario: Transient suppression on Ethernet PHY differential pairs and RS-485 data lines exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Bi-directional TVS placed across differential signal lines to clamp common-mode and differential-mode transients simultaneously. Use Value: Symmetric clamping ensures balanced signal integrity; 60 V VWM avoids interference with 48 V PoE signaling while suppressing >1 kV surges. | Use Scenario: Secondary-side overvoltage protection on 5 V/9 V USB-C PD adapter outputs against regulator failure or feedback loop disruption. IC Role / Device Role / Timing Role: Last-line defense parallel to output capacitor, clamping fault voltages before they reach connected devices. Use Value: 1500 W PPPM rating absorbs energy from sustained overvoltage events; RoHS-compliant E3 suffix supports global compliance 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 |
|---|---|---|---|
| SAC60C | Lower PPPM (600 W), same VWM (60 V), smaller DO-214AC (SMA) package | Not AEC-Q101 qualified; limited to consumer/industrial use where 1500 W surge margin is not required | Select when board space is constrained and surge threat level is moderate (e.g., internal signal lines) |
| TPSMD60CA | Same PPPM (1500 W), identical VWM/VBR specs, but optimized for lower clamping voltage (VC = 93.6 V @ 15.5 A) | Also AEC-Q101 qualified; slightly tighter VBR tolerance (±3.5% vs. ±5%) and lower RθJA (65 °C/W) | Prefer when minimizing clamped voltage is critical for 3.3 V logic protection or when thermal management is challenging |
Compared with SMCJ60C-E3/57T, SAC60C offers footprint reduction at the cost of surge capacity and automotive qualification, while TPSMD60CA delivers tighter clamping and better thermal performance in the same application space-making it suitable for next-generation designs demanding higher reliability margins.

FAQ
What is the polarity configuration of SMCJ60C-E3/57T?
The SMCJ60C-E3/57T is a bi-directional TVS diode with symmetrical construction-neither terminal is designated anode or cathode. It clamps voltage transients equally in both directions, and no polarity marking appears on the DO-214AB package. This makes SMCJ60C-E3/57T ideal for protecting AC-coupled or differential signal paths where polarity reversal is possible.
Is SMCJ60C-E3/57T qualified for automotive applications?
Yes, SMCJ60C-E3/57T is AEC-Q101 qualified, confirming its suitability for automotive electronic systems including engine control units, body electronics, and ADAS sensor interfaces. The qualification covers stress testing for temperature cycling, humidity, mechanical shock, and surge endurance-ensuring reliability under real-world vehicle operating conditions.
What is the maximum clamping voltage of SMCJ60C-E3/57T under surge conditions?
The maximum clamping voltage (VC) of SMCJ60C-E3/57T is 96.8 V at its rated peak pulse current (IPPM) of 15.5 A, measured using the standard 10/1000 µs waveform. This value represents the upper limit of voltage seen by protected circuitry during worst-case transient events, ensuring downstream components like microcontrollers and transceivers remain within safe operating limits.
Does SMCJ60C-E3/57T require special PCB layout considerations?
Yes-SMCJ60C-E3/57T must be mounted on minimum 8.0 mm × 8.0 mm copper pads per terminal to achieve its full 1500 W peak pulse power rating. Smaller pads cause thermal derating; layout should minimize trace inductance between the device and protected node, and avoid routing sensitive signals near the TVS body to prevent coupling.
How does the E3/57T suffix affect SMCJ60C-E3/57T's compliance and packaging?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting JESD 201 Class 1A whisker resistance; "57T" denotes packaging in 7-inch plastic tape-and-reel format containing 850 units. This configuration supports high-volume SMT assembly and satisfies environmental compliance requirements for global markets.
