Product details
Overview
SMCJ10CAHE3/9AT from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 10 V stand-off voltage (VWM), 1500 W peak pulse power (PPPM), and clamps transients to ≤17.0 V at 88.2 A (10/1000 µs waveform), with AEC-Q101 qualification for automotive use.
For engineers reviewing the SMCJ10CAHE3/9AT datasheet, SMCJ10CAHE3/9AT pinout, SMCJ10CAHE3/9AT application, or SMCJ10CAHE3/9AT equivalent, key selection criteria include bidirectional clamping capability, low clamping voltage under surge, AEC-Q101 qualification status, and compatibility with automated SMT placement 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 fast energy dissipation during ESD or lightning-induced transients.
The device is rated for 150 °C maximum junction temperature and exhibits a typical thermal resistance of 75 °C/W (junction-to-ambient) on standard PCB pads. Its 0.078 %/°C temperature coefficient of VBR ensures predictable voltage drift across operating temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse working voltage before clamping initiates; defines safe operating margin for protected circuitry. |
| VBR min/max | 11.1 V / 12.3 V at 1.0 mA - Verified breakdown range ensures reliable turn-on during overvoltage events. |
| VC @ IPPM | ≤17.0 V at 88.2 A - Clamping voltage under full-rated 10/1000 µs surge; determines maximum stress imposed on downstream ICs. |
| PPPM | 1500 W - Peak pulse power handling capacity; enables protection against high-energy transients per IEC 61000-4-5 Level 4. |
| ID @ VWM | ≤5.0 µA - Reverse leakage current at stand-off voltage; critical for low-power sensor or battery-backed circuits. |
| TJ max | +150 °C - Maximum junction temperature rating; supports operation in under-hood automotive environments. |
| Package | SMC (DO-214AB) - Surface-mount outline with 8.13 mm × 6.22 mm footprint and 2.62 mm height; compatible with J-STD-020 MSL level 1 reflow. |
Pinout & Package
SMCJ10CAHE3/9AT uses a two-terminal SMC (DO-214AB) package with no polarity marking-consistent with bidirectional functionality. Terminals are matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102, and meet JESD 201 Class 2 whisker test requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically; conducts surge current in either direction when voltage exceeds VBR. |
| Case (body) | Thermal and mechanical interface | Plastic body provides UL 94 V-0 flammability rating; copper pad layout (8.0 mm × 8.0 mm per terminal) required for rated PPPM performance. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., CAN, RS-485), and ungrounded interfaces without polarity constraints. |
| AEC-Q101 qualified | Validated for automotive applications including engine control units, ADAS sensors, and infotainment systems requiring reliability under thermal cycling and vibration. |
| Glass passivated junction | Ensures stable VBR tolerance and low leakage over lifetime, critical for long-term field reliability in industrial and automotive deployments. |
| Low clamping ratio (VC/VBR ≈ 1.53) | Minimizes voltage overshoot during surge events, reducing risk of latch-up or damage to 3.3 V or 5 V logic interfaces. |
| MSL level 1 rating | Supports standard reflow profiles up to 260 °C peak without moisture-related failure, eliminating bake-out requirements in production. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|

IC Role / Device Role / Timing Role: Low-capacitance TVS (typ. <100 pF) suppressing ±15 kV contact discharge per IEC 61000-4-2 without signal attenuation. Use Value: Prevents port lockup or PHY damage during consumer ESD events while maintaining USB full-speed timing compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC10CA | Lower PPPM (600 W), same VWM (10 V), SOD-123FL package (smaller footprint, lower thermal mass) | Not rated for AEC-Q101; limited to commercial-grade consumer/industrial use | Select when board space is constrained and surge energy is ≤600 W; verify thermal derating on small pads. |
| 1.5KE10CA | Same VWM (10 V) and bidirectional function, but through-hole DO-201 package; higher VBR (11.1–12.3 V), identical VC (17.0 V) | Requires wave soldering or hand assembly; unsuitable for high-density SMT designs | Choose only for legacy through-hole systems or prototyping where rework flexibility outweighs automation needs. |
Compared with SAC10CA and 1.5KE10CA, SMCJ10CAHE3/9AT delivers higher surge robustness (1500 W vs. 600 W or equivalent), AEC-Q101 qualification for automotive deployment, and SMT compatibility-making it optimal for volume-manufactured, thermally demanding, or safety-critical applications.

FAQ
What does the "CA" suffix indicate in SMCJ10CAHE3/9AT?
The "CA" suffix denotes a bidirectional configuration, meaning SMCJ10CAHE3/9AT provides symmetrical clamping in both polarities-ideal for protecting AC-coupled lines, differential interfaces like CAN or RS-485, and ungrounded circuits where polarity cannot be guaranteed. Unlike unidirectional variants (e.g., SMCJ10A), it has no cathode band marking.
Is SMCJ10CAHE3/9AT qualified for automotive applications?
Yes, SMCJ10CAHE3/9AT is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3". This qualification validates its reliability under automotive temperature cycling, humidity bias, mechanical shock, and vibration requirements-making it suitable for engine control, ADAS, and body electronics systems.
What is the maximum clamping voltage of SMCJ10CAHE3/9AT under surge conditions?
The maximum clamping voltage (VC) of SMCJ10CAHE3/9AT is 17.0 V when subjected to its rated peak pulse current of 88.2 A using the standard 10/1000 µs waveform. This value is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
How does the SMC (DO-214AB) package of SMCJ10CAHE3/9AT affect thermal performance?
The SMC (DO-214AB) package of SMCJ10CAHE3/9AT delivers 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 enables effective heat dissipation during repetitive surge events, supporting sustained operation up to +150 °C junction temperature in properly laid out PCBs.
Can SMCJ10CAHE3/9AT replace unidirectional TVS diodes in existing designs?
No-SMCJ10CAHE3/9AT is strictly bidirectional and lacks polarity marking, so it cannot directly replace unidirectional TVS diodes (e.g., SMCJ10A) without circuit review. Unidirectional parts conduct only in reverse bias and require correct cathode orientation; substituting SMCJ10CAHE3/9AT may compromise protection if forward-biased conduction paths exist in the design.
