Product details
Overview
SMCJ10CAHM3/I 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 standoff voltage (VWM), 17.0 V clamping voltage at 88.2 A peak pulse current (10/1000 µs), and 1500 W peak pulse power dissipation - ideal for protecting automotive sensor signal lines, industrial I/O ports, and DC power rails against ESD and inductive switching transients.
For engineers reviewing the SMCJ10CAHM3/I datasheet, SMCJ10CAHM3/I pinout, SMCJ10CAHM3/I application, or SMCJ10CAHM3/I equivalent, key selection criteria include bidirectional clamping symmetry, low clamping ratio (VC/VWM = 1.7), AEC-Q101 qualification, halogen-free RoHS compliance (HM3 suffix), and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
The SMCJ10CAHM3/I operates as a silicon avalanche diode with symmetrical breakdown in both polarities, enabling protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and repeatable clamping performance across temperature (–55 °C to +150 °C).
It delivers fast response time (<1.0 ps) to transient events and maintains low incremental surge resistance, resulting in consistent 17.0 V clamping under 10/1000 µs surges up to 88.2 A. The device meets MSL Level 1 per J-STD-020 and supports lead-free reflow up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 11.1 V / 12.3 V at 1.0 mA - guaranteed symmetric breakdown threshold in both directions |
| VC @ IPPM | 17.0 V at 88.2 A - clamping voltage limits protected circuit stress during worst-case surge |
| PPPM | 1500 W - peak transient energy handling capability with 10/1000 µs waveform |
| ID @ VWM | ≤1.0 µA - ultra-low leakage preserves signal integrity in high-impedance interfaces |
| TJ max | +150 °C - enables operation in under-hood automotive and industrial environments |
| Package | SMC (DO-214AB) - surface-mount footprint compatible with IPC-7351B standard pad layout |
Pinout & Package
SMCJ10CAHM3/I uses the SMC (DO-214AB) package: a molded, rectangular surface-mount case with two coplanar matte tin-plated leads. No polarity marking is present, as the device is bidirectional.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically; voltage clamping occurs regardless of polarity applied |
| Case (body) | Non-electrical mechanical interface | No internal connection; thermal path to PCB copper pads improves power derating |

FAQ
What is the clamping voltage of SMCJ10CAHM3/I at its rated peak pulse current?
The SMCJ10CAHM3/I has a maximum clamping voltage (VC) of 17.0 V when subjected to its rated peak pulse current (IPPM) of 88.2 A under the standard 10/1000 µs waveform. This value is measured at room temperature and defines the upper voltage limit imposed on protected circuitry during surge events. The SMCJ10CAHM3/I maintains this clamping performance across its full operating temperature range.
Is SMCJ10CAHM3/I suitable for automotive applications?
Yes, SMCJ10CAHM3/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction with JEDEC JESD201 Class 2 whisker resistance. It is explicitly rated for automotive use in engine control units, body electronics, and ADAS sensor interfaces - meeting stringent requirements for thermal cycling, humidity resistance, and surge survivability defined in ISO 16750 and ISO 7637-2.
How does the bidirectional design of SMCJ10CAHM3/I affect its circuit implementation?
The bidirectional design of SMCJ10CAHM3/I means it clamps symmetrically in both polarities, eliminating the need to observe orientation during placement. This simplifies layout for AC-coupled signals, differential buses (e.g., CAN, RS-485), or floating power domains. Unlike unidirectional TVS diodes, SMCJ10CAHM3/I requires no cathode marking and functions identically regardless of voltage polarity - reducing assembly errors and enabling single-part logistics for dual-polarity protection.
What is the thermal resistance of SMCJ10CAHM3/I, and how does it impact power derating?
The SMCJ10CAHM3/I has a typical junction-to-lead thermal resistance (RθJL) of 15 °C/W and junction-to-ambient (RθJA) of 75 °C/W when mounted on minimum recommended 8.0 mm × 8.0 mm copper pads. These values determine safe operating area: at 100 °C ambient, its 6.5 W steady-state power dissipation derates to ~4.3 W, while its 1500 W transient rating remains valid for short-duration pulses per Fig. 2 in the datasheet.
Does SMCJ10CAHM3/I require special handling or packaging due to moisture sensitivity?
No - SMCJ10CAHM3/I is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and may be processed using standard SMT reflow profiles without dry-packaging or baking. Its moisture sensitivity level allows direct placement from tape-and-reel (I-type carrier) into production, supporting high-throughput automated assembly without process modification or yield risk from popcorning.
