Product details
Overview
SMCJ10C-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 10 V stand-off voltage (VWM), 1500 W peak pulse power (PPPM), 17.0 V maximum clamping voltage at 88.2 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMCJ10C-E3/9AT datasheet, SMCJ10C-E3/9AT pinout, SMCJ10C-E3/9AT application, or SMCJ10C-E3/9AT equivalent, this device is selected for robust overvoltage protection in automotive sensor interfaces, industrial I/O lines, and telecom surge-prone signal paths where bidirectional clamping, low leakage (<5.0 µA at VWM), and MSL Level 1 reflow compatibility are required.
Technical Context
The SMCJ10C-E3/9AT operates as a bi-directional avalanche diode with symmetrical breakdown characteristics - minimum VBR of 11.1 V and maximum of 12.3 V at 1.0 mA test current. Its clamping action begins at VWM = 10 V and limits transient energy to ≤17.0 V up to 88.2 A (10/1000 µs waveform), enabling protection of downstream ICs without forward conduction during normal operation.
Thermally, it sustains junction temperatures from –55 °C to +150 °C, with RθJA = 75 °C/W and RθJL = 15 °C/W. The device uses glass-passivated junction technology, meets UL 94 V-0 flammability rating, and is qualified per AEC-Q101 for automotive under-hood and chassis applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR (min/max) | 11.1 V / 12.3 V at 1.0 mA - Ensures consistent bi-directional breakdown threshold across production lots |
| VC @ IPPM | 17.0 V at 88.2 A - Clamping voltage under 10/1000 µs surge defines protected circuit's worst-case overvoltage exposure |
| PPPM | 1500 W - Peak transient power handling capacity determines survivability against lightning-induced surges |
| ID @ VWM | ≤5.0 µA - Low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits |
| TJ max. | +150 °C - Enables deployment in engine control units, motor drives, and other high-ambient-temperature environments |
| Package | DO-214AB (SMCJ) - Surface-mount outline with 8.0 mm × 8.0 mm copper pad footprint for optimal thermal dissipation |
Pinout & Package
SMCJ10C-E3/9AT is a two-terminal bi-directional TVS diode in DO-214AB (SMCJ) package. No polarity marking is present on bi-directional variants; both terminals are functionally identical and interchangeable in circuit layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path | Either terminal conducts during positive or negative voltage excursions beyond VBR - no DC bias dependency |
| Case (cathode band absent) | Non-functional mechanical reference | Bi-directional construction eliminates cathode identification; mounting orientation has no electrical impact |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA-E3/61T | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher VC (18.2 V at 24.7 A) | Suitable for space-constrained consumer electronics but not automotive-level surge immunity | Select when board area is critical and peak surge energy is ≤400 W |
| 1.5KE10CA | Through-hole TO-218 package, same VWM/VC specs, higher thermal mass but incompatible with SMT assembly | Used in legacy industrial power supplies where manual assembly or high-reliability through-hole mounting is required | Choose only if SMT process is unavailable or thermal cycling demands greater mechanical robustness |
Compared with SMAJ10CA-E3/61T and 1.5KE10CA, the SMCJ10C-E3/9AT delivers 3.75× higher surge power handling in an SMT-compatible package while maintaining AEC-Q101 qualification - making it the preferred choice for automotive and high-reliability industrial designs requiring both performance and manufacturability.

FAQ
What does the "C" suffix indicate in SMCJ10C-E3/9AT?
The "C" in SMCJ10C-E3/9AT denotes bi-directional configuration - meaning the device provides symmetrical clamping for both positive and negative voltage transients. Unlike uni-directional variants (e.g., SMCJ10A), it has no cathode marking and functions identically regardless of terminal orientation. This makes SMCJ10C-E3/9AT ideal for AC-coupled or differential signal lines where polarity reversal is possible.
Is SMCJ10C-E3/9AT RoHS compliant and halogen-free?
Yes, SMCJ10C-E3/9AT is RoHS-compliant per Directive 2011/65/EU and halogen-free per JEDEC JS709A standards. The "E3" suffix confirms compliance with JESD201 Class 1A whisker testing, and the molding compound meets UL 94 V-0 flammability requirements - satisfying environmental and safety mandates for automotive and industrial end equipment.
How does SMCJ10C-E3/9AT differ from SMCJ10A-E3/9AT?
SMCJ10C-E3/9AT is bi-directional with symmetrical breakdown (VBR min/max = 11.1 V / 12.3 V), while SMCJ10A-E3/9AT is uni-directional and features a cathode band. The uni-directional version conducts only during reverse-biased overvoltage and exhibits forward voltage drop (~3.5 V at 100 A); SMCJ10C-E3/9AT has no forward conduction path and clamps equally in both polarities - critical for protecting AC or floating signal lines.
What is the maximum PCB pad size recommended for SMCJ10C-E3/9AT thermal performance?
Vishay specifies a minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pad per terminal for SMCJ10C-E3/9AT to achieve rated PPPM of 1500 W and thermal resistance RθJA = 75 °C/W. Reducing pad area below this degrades surge capability and increases junction temperature - potentially triggering premature failure during repeated transients. Thermal vias beneath pads further improve heat dissipation in high-power layouts.
Can SMCJ10C-E3/9AT be used in place of a unidirectional TVS in a DC power rail?
Yes, SMCJ10C-E3/9AT can replace a uni-directional TVS on a DC rail, but with trade-offs: it offers identical clamping performance above 10 V in either polarity, yet lacks forward conduction - so it won't conduct during reverse-polarity misconnection. For pure overvoltage protection (e.g., load dump), SMCJ10C-E3/9AT performs equivalently; however, for reverse-voltage blocking, a dedicated uni-directional part or additional series diode is required.
