Product details
Overview
SMCJ10AHE3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage at 88.2 A peak pulse current (10/1000 µs), and 1500 W peak pulse power dissipation - ideal for safeguarding automotive ECUs, industrial sensor interfaces, and power supply inputs against ESD and load dump transients.
For engineers reviewing the SMCJ10AHE3_A/I datasheet, SMCJ10AHE3_A/I pinout, SMCJ10AHE3_A/I application, or SMCJ10AHE3_A/I equivalent, key selection criteria include its AEC-Q101 qualification, low 0.078 %/°C VBR temperature coefficient, 1.0 µA max reverse leakage at VWM, and compatibility with automated SMT assembly on standard 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device that remains high-impedance below 10 V and rapidly transitions to low-impedance conduction above its 11.1–12.3 V breakdown range (tested at 1.0 mA). Its glass-passivated junction ensures stable avalanche behavior and long-term reliability under repetitive surge stress.
The SMCJ10AHE3_A/I is rated for 150 °C maximum junction temperature and exhibits 75 °C/W junction-to-ambient thermal resistance when mounted per recommended pad layout. Its unidirectional polarity - marked by a cathode band - enables precise integration into DC-biased circuits without reverse conduction risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 10 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC bias margin. |
| VBR (Breakdown Voltage) | 11.1–12.3 V at 1.0 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 17.0 V at 88.2 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge; critical for IC survivability. |
| PPPM (Peak Pulse Power) | 1500 W - Energy-handling capacity for standardized 10/1000 µs waveform; supports automotive load-dump immunity. |
| ID (Reverse Leakage) | 5.0 µA max at VWM - Low leakage preserves system efficiency and avoids false triggering in high-impedance nodes. |
| TJ max | +150 °C - Enables operation in under-hood automotive environments and industrial enclosures without derating. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V supply input of an automotive body control module (BCM) against load dump (ISO 16750-2 Test 4a) and jump-start surges. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between battery rail and upstream fuse/diode; conducts only during overvoltage events. Use Value: Limits transient voltage to ≤17.0 V, preventing damage to downstream LDOs, microcontrollers, and CAN transceivers while maintaining system uptime. | Use Scenario: Safeguarding analog output (4–20 mA) and digital I/O lines of an industrial pressure sensor exposed to motor switching noise and EFT bursts. IC Role / Device Role / Timing Role: Point-of-entry TVS on each signal line, referenced to local ground; absorbs sub-microsecond transients before reaching precision ADC front-end. Use Value: Maintains signal integrity with <5.0 µA leakage at 10 V, enabling accurate low-current measurements without offset drift or calibration loss. |
| DC-DC Converter Input Protection | Telecom Power Supply Clamp |
Use Scenario: Shielding the input stage of a 24 V input buck converter used in railway signaling equipment from induced lightning surges (IEC 61000-4-5, 2 kV line-earth). IC Role / Device Role / Timing Role: Primary overvoltage clamp located upstream of input filter capacitor; activated within nanoseconds of surge onset. Use Value: Delivers 1500 W pulse handling with 17.0 V clamping, allowing use of smaller input capacitors and reducing board space versus multi-stage protection schemes. | Use Scenario: Protecting -48 V DC telecom power distribution boards from accidental polarity reversal and hot-swap transients during field maintenance. IC Role / Device Role / Timing Role: Unidirectional TVS connected cathode-to-rail to clamp positive excursions while blocking reverse conduction during fault conditions. Use Value: Withstands 200 A non-repetitive forward surge (IFSM), enabling reliable operation during repeated hot-plug cycles without degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10AHE3_A/I | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher RθJA (110 °C/W). | Suitable for lower-energy transients (e.g., ESD-only) where board space is constrained and thermal mass is limited. | Select when cost and footprint are prioritized over automotive-grade surge immunity. |
| SMCJ10CAHE3_A/I | Bidirectional variant; same VWM (10 V), symmetric clamping in both polarities; identical PPPM and package. | Required for AC-coupled or floating signal lines (e.g., RS-485, CAN bus) where polarity reversal may occur. | Choose only if bidirectional protection is mandated by system architecture - not a drop-in replacement for unidirectional use. |
Compared with SMAJ10AHE3_A/I, the SMCJ10AHE3_A/I delivers 3.75× higher surge energy handling and superior thermal performance; versus SMCJ10CAHE3_A/I, it offers optimized clamping for DC-biased rails but lacks reverse-polarity protection capability.

FAQ
What is the breakdown voltage range of the SMCJ10AHE3_A/I?
The SMCJ10AHE3_A/I has a specified breakdown voltage (VBR) range of 11.1 V to 12.3 V at a test current of 1.0 mA. This range reflects manufacturing tolerance and ensures consistent clamping behavior across production lots. The value is measured per ANSI/IEEE C62.35 standards and confirmed in Vishay's official datasheet revision 09-Jan-2024 (Document Number: 88394). This parameter directly determines the minimum overvoltage threshold at which the SMCJ10AHE3_A/I begins conducting.
Is the SMCJ10AHE3_A/I suitable for automotive applications?
Yes, the SMCJ10AHE3_A/I is AEC-Q101 qualified and explicitly designated for automotive use via its "HE3" suffix. It meets rigorous stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC-Q101 Rev G. Its 150 °C maximum junction temperature, low leakage (<5.0 µA), and 1500 W surge rating make it appropriate for under-hood ECUs, infotainment power supplies, and ADAS sensor modules. The SMCJ10AHE3_A/I is listed in Vishay's automotive-grade ordering matrix with full traceability.
What does the "_A/I" suffix mean in SMCJ10AHE3_A/I?
The "_A/I" suffix in SMCJ10AHE3_A/I indicates two attributes: "A" denotes the revision code (per Vishay's document control), and "I" specifies the packaging format - 13-inch diameter plastic tape and reel, with a base quantity of 3500 units. This matches the ordering information table in the official datasheet (page 3), where SMCJ10AHE3_A/I is explicitly called out alongside its 7-inch reel variant (SMCJ10AHE3_A/H). The "HE3" portion confirms RoHS compliance and AEC-Q101 qualification.
How does the clamping voltage of SMCJ10AHE3_A/I compare to its stand-off voltage?
The SMCJ10AHE3_A/I has a stand-off voltage (VWM) of 10 V and a maximum clamping voltage (VC) of 17.0 V at 88.2 A (10/1000 µs waveform). This 7.0 V differential represents the voltage "headroom" the protected circuit must tolerate during surge events. The ratio VC/VWM = 1.7 ensures effective protection while minimizing stress on downstream components - a key advantage over older TVS families with ratios >2.0. This performance is validated per JEDEC test methods and documented in the Electrical Characteristics table for SMCJ10A on page 2 of the datasheet.
Can SMCJ10AHE3_A/I be used in bidirectional signal protection?
No, the SMCJ10AHE3_A/I is a unidirectional TVS diode and must not be used for bidirectional signal protection. Its cathode band marking and asymmetric IV curve mean it conducts only when the cathode is more positive than the anode. For bidirectional applications like RS-485 or CAN bus, the correct variant is SMCJ10CAHE3_A/I - a distinct part with symmetrical breakdown in both directions. Using SMCJ10AHE3_A/I in such roles risks failure during negative transients, as confirmed in Vishay's "DEVICES FOR BIDIRECTION APPLICATIONS" section (page 1).
