Product details
Overview
SMCJ10CHE3/9AT 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 10 V stand-off 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 - deployed on automotive power lines, industrial sensor interfaces, and DC input rails.
For engineers reviewing the SMCJ10CHE3/9AT datasheet, SMCJ10CHE3/9AT pinout, SMCJ10CHE3/9AT application, or SMCJ10CHE3/9AT equivalent, key selection criteria include its AEC-Q101 qualification, bi-directional symmetry, low clamping ratio (VC/VWM = 1.7), RoHS-compliant HE3 suffix, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ10CHE3/9AT operates as a bi-directional avalanche diode, exhibiting symmetrical breakdown behavior in both polarities with minimum breakdown voltage (VBR) of 11.1 V and maximum of 12.3 V at 1.0 mA test current. Its clamping action limits transient-induced voltage excursions to ≤17.0 V under 88.2 A surge, enabling protection of downstream ICs rated for ≤16 V absolute maximum.
Thermally, it sustains junction temperatures from −55 °C to +150 °C, with thermal resistance junction-to-lead (RθJL) of 15 °C/W and junction-to-ambient (RθJA) of 75 °C/W on recommended pad layout. The device meets MSL level 1 per J-STD-020 and passes JESD 201 class 2 whisker testing due to its HE3 suffix.

Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting LIN bus transceivers and microcontroller I/O against load dump and jump-start transients in 12 V vehicle systems. IC Role / Device Role / Timing Role: Bi-directional TVS placed between power rail and ground, clamping surges within 1 ns response time. Use Value: Maintains <17.0 V clamping at 88.2 A ensures compliance with ISO 16750-2 Class D (35 V/100 ms) and prevents latch-up in 5 V logic. | Use Scenario: Safeguarding analog outputs of pressure/temperature sensors connected to PLC analog input modules. IC Role / Device Role / Timing Role: Parallel-connected transient suppressor across sensor output and reference ground to shunt ESD and switching noise. Use Value: 5.0 µA leakage at 10 V VWM avoids loading of high-impedance ratiometric sensor bridges or 4–20 mA loop drivers. |
| DC Input Rail Protection | Telecom Equipment Surge Suppression |
Use Scenario: Front-end protection of 12 V DC-DC converters in network switches and PoE injectors exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Primary-level TVS mounted directly at connector entry point, upstream of filtering and regulation stages. Use Value: 1500 W PPPM rating handles IEC 61000-4-5 Combination Wave (1.2/50 µs + 8/20 µs) up to 4 kV line-to-ground. | Use Scenario: Secondary-side protection of Ethernet PHY interface lines (MDI) in base station backhaul units. IC Role / Device Role / Timing Role: Bi-directional clamp on differential pair, referenced to local ground plane to suppress common-mode transients. Use Value: Symmetrical VBR (11.1–12.3 V) ensures balanced clamping on both conductors, preserving signal integrity during fast-rising EFT bursts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA-E3/52T | Lower PPPM (600 W), smaller SMB package (DO-214AA), same VWM/VC specs | Reduced surge handling; suitable only for lower-energy threats like ESD or capacitive coupling | Select when board space is constrained and threat level does not exceed IEC 61000-4-2 ±8 kV contact |
| SMCJ10AHE3/9AT | Uni-directional variant with cathode band marking; identical VWM, VBR, VC, and PPPM | Requires correct polarity orientation; unsuitable for AC or floating lines | Choose only if circuit topology guarantees unidirectional voltage polarity and grounding scheme permits asymmetric protection |
Compared with SMCJ10CHE3/9AT, the SMBJ10CA-E3/52T offers footprint reduction at the cost of 60% lower surge capacity, while the SMCJ10AHE3/9AT trades bi-directional flexibility for strict polarity alignment - making SMCJ10CHE3/9AT optimal for universal placement on undetermined or AC-coupled nodes.

FAQ
What is the clamping voltage of SMCJ10CHE3/9AT at its rated peak pulse current?
The SMCJ10CHE3/9AT has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPPM) of 88.2 A using the standard 10/1000 µs waveform. This value is measured under defined test conditions per ANSI/IEEE C62.35 and ensures predictable voltage limiting during surge events. The SMCJ10CHE3/9AT maintains this clamping performance across its full operating temperature range.
Is SMCJ10CHE3/9AT suitable for automotive applications?
Yes, SMCJ10CHE3/9AT is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass passivated junctions, MSL Level 1 moisture sensitivity, and JESD 201 class 2 whisker resistance - all validated per automotive stress test requirements. The SMCJ10CHE3/9AT is commonly deployed in engine control units, body electronics, and infotainment power rails where ISO 7637-2 and ISO 16750-2 compliance is required.
What does the "HE3" suffix indicate in SMCJ10CHE3/9AT?
Within SMCJ10CHE3/9AT, the "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 class 2 whisker resistance. The "H" signifies automotive grade, "E3" confirms matte tin plating meeting J-STD-002 solderability and RoHS Directive 2011/65/EU. This distinguishes SMCJ10CHE3/9AT from commercial-grade "E3" variants and confirms suitability for mission-critical automotive and industrial designs.
How does SMCJ10CHE3/9AT differ from uni-directional SMCJ10AHE3/9AT?
The SMCJ10CHE3/9AT is bi-directional with no polarity marking and symmetrical electrical characteristics in both directions, whereas SMCJ10AHE3/9AT is uni-directional with a cathode band and only conducts in reverse bias. Both share identical VWM (10 V), VBR (11.1–12.3 V), VC (17.0 V), and PPPM (1500 W), but SMCJ10CHE3/9AT eliminates orientation risk during assembly and supports AC or floating node protection - a key distinction in the SMCJ10CHE3/9AT datasheet.
What PCB pad layout is recommended for optimal thermal and surge performance of SMCJ10CHE3/9AT?
Vishay specifies a minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pad area per terminal for SMCJ10CHE3/9AT to achieve rated PPPM and thermal dissipation. This layout ensures adequate heat spreading during surge events and maintains RθJA at 75 °C/W. The SMCJ10CHE3/9AT must be placed with short, wide traces to minimize inductance and preserve sub-nanosecond response - critical for effective clamping of fast transients.
