Product details
Overview
SMCJ10CA-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 signal or power lines. It features 10 V standoff voltage (VWM), 17.0 V maximum clamping voltage (VC) at 88.2 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 µs waveform.
For engineers reviewing the SMCJ10CA-E3/9AT datasheet, SMCJ10CA-E3/9AT pinout, SMCJ10CA-E3/9AT application, or SMCJ10CA-E3/9AT equivalent, key selection criteria include bidirectional surge protection capability, low clamping ratio (VC/VWM = 1.7), AEC-Q101 qualification eligibility, and compatibility with automated SMT assembly on 8 mm × 8 mm copper pads.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal lines without polarity concerns. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<5.0 µA at VWM), while the low incremental surge resistance supports consistent clamping under repetitive transient stress.
The device meets J-STD-020 MSL Level 1 moisture sensitivity and withstands 260 °C lead-free reflow peaks. Thermal resistance from junction to ambient is 75 °C/W, requiring thermal pad design per recommended 8.0 mm × 8.0 mm copper area per terminal to sustain rated PPPM under derated conditions above 25 °C.
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 |
|---|---|---|---|
| SMAJ10CA-E3/61T | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher RθJA (110 °C/W). | Suitable for lower-energy surges (e.g., IEC 61000-4-2) but not ISO 7637-2 load dump; limited thermal margin in confined layouts. | Select when space-constrained and surge energy is ≤400 W; verify thermal derating for sustained operation. |
| SMCJ10CAHM3/9AT | Halogen-free, RoHS-compliant variant with identical electrical specs and AEC-Q101 qualification path. | No functional difference; used where halogen-free compliance is mandated (e.g., EU automotive Tier 1 supply chain). | Choose for green manufacturing requirements without compromising performance or footprint. |
Compared with SMCJ10CA-E3/9AT, SMAJ10CA-E3/61T offers reduced surge handling and thermal capability in a smaller package, while SMCJ10CAHM3/9AT delivers identical protection with halogen-free materials-making it a drop-in material-compliance upgrade rather than a functional alternative.

FAQ
What is the clamping voltage of SMCJ10CA-E3/9AT at its rated peak pulse current?
The SMCJ10CA-E3/9AT clamps to a maximum of 17.0 V when subjected to its rated 88.2 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured at the device terminals with specified PCB thermal pads (8.0 mm × 8.0 mm copper per terminal), ensuring repeatable performance in production designs.
Is SMCJ10CA-E3/9AT suitable for automotive applications requiring AEC-Q101 qualification?
SMCJ10CA-E3/9AT itself is commercial-grade, but Vishay offers the functionally identical SMCJ10CAHE3/9AT variant-RoHS-compliant and AEC-Q101 qualified. The die, package, and electrical characteristics are identical; only the suffix and qualification documentation differ. Designers targeting automotive use should specify the HE3 version for formal qualification compliance.
How does the bidirectional nature of SMCJ10CA-E3/9AT affect PCB layout compared to unidirectional TVS diodes?
SMCJ10CA-E3/9AT has no polarity marking and functions identically regardless of orientation, eliminating orientation checks during SMT placement and removing risk of reverse installation. Unlike unidirectional types (e.g., SMCJ10A), it requires no cathode band alignment-simplifying layout, reducing assembly errors, and enabling symmetric placement on differential lines like CAN or RS-485.
What is the maximum allowable reverse leakage current for SMCJ10CA-E3/9AT at its standoff voltage?
At its 10 V standoff voltage (VWM), the SMCJ10CA-E3/9AT exhibits a maximum reverse leakage current (ID) of 5.0 µA at 25 °C. This low leakage ensures minimal loading on high-impedance circuits such as sensor bias networks or precision reference paths, preserving accuracy without requiring additional compensation.
Can SMCJ10CA-E3/9AT be used in parallel to increase surge current handling?
No-SMCJ10CA-E3/9AT is not designed for parallel operation. Variations in breakdown voltage (11.1–12.3 V) cause uneven current sharing, risking thermal runaway in one device. For higher surge ratings, select a higher-power TVS (e.g., SMCJ15CA) or implement staged protection with upstream current-limiting elements instead of paralleling.
