Product details
Overview
SMCJ5.0CAHM3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients up to 1500 W peak pulse power with 9.2 V maximum clamping voltage at 163 A peak pulse current and 5.0 V stand-off voltage. It protects sensitive ICs and MOSFETs in automotive and industrial power rails.
For engineers reviewing the SMCJ5.0CAHM3_A/I datasheet, SMCJ5.0CAHM3_A/I pinout, SMCJ5.0CAHM3_A/I application, or SMCJ5.0CAHM3_A/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 1500 W surge rating, low 7.07 V max breakdown voltage, and halogen-free RoHS-compliant construction.
Technical Context
This device operates as a voltage-clamping protector using an avalanche junction structure, responding within picoseconds to transient overvoltages. Its bidirectional symmetry ensures identical electrical behavior in both polarities, with specified breakdown voltage range of 6.40 V to 7.07 V at 10 mA test current and temperature coefficient of 0.057 %/°C.
Thermal performance is defined by 75 °C/W junction-to-ambient thermal resistance and 15 °C/W junction-to-lead resistance. It meets J-STD-020 MSL Level 1 and supports reflow soldering up to 260 °C peak temperature, with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102.
Key Specifications

Pinout & Package
SMCJ5.0CAHM3_A/I uses the SMC (DO-214AB) package: a surface-mount, molded plastic case with two coplanar terminals and no polarity marking (bidirectional configuration). Dimensions: 7.75 mm × 6.22 mm × 2.62 mm (L × W × H), with cathode/anode terminals symmetrically arranged for dual-direction conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode / Cathode (bidirectional) | Either terminal serves as anode or cathode depending on transient polarity; no band marking |
| Terminal 2 | Anode / Cathode (bidirectional) | Electrically identical to Terminal 1; symmetrical conduction path enables AC/DC line protection |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable, repeatable avalanche clamping with low leakage and long-term reliability under repeated surges |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients, improving protection margin for downstream ICs |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking, reducing manufacturing overhead |
| 1500 W 10/1000 µs rating | Supports robust protection against IEC 61000-4-5 Level 4 surges (4 kV line-earth) in compact layout |
| Halogen-free & RoHS-compliant (HM3) | Fulfills automotive OEM environmental requirements and simplifies end-of-life compliance reporting |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
|
Use Scenario: Protecting 5 V CAN transceiver power inputs against load dump and jump-start transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed between VCC and GND, absorbing surge energy before it reaches the transceiver. Use Value: Maintains 5.0 V system integrity with 9.2 V clamping ceiling, preventing latch-up or permanent damage during 12 V battery system faults. |
Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA current loop) from ESD and inductive switching noise in factory automation sensors. IC Role / Device Role / Timing Role: Low-capacitance TVS shunting transient energy across signal and return paths without distorting 1 kHz–10 kHz sensor bandwidth. Use Value: Delivers sub-10 ns response and <1 µA leakage at 5 V, preserving signal fidelity while meeting IEC 61000-4-2 Level 4 (8 kV contact). |
| Consumer USB Port ESD Protection | Telecom DSL Line Surge Suppression |
|
Use Scenario: Secondary-level protection on 5 V VBUS lines in USB 2.0 host ports subjected to repeated human-body-model ESD events. IC Role / Device Role / Timing Role: Standoff-rated TVS operating in parallel with primary polymer PTC and low-capacitance ESD array. Use Value: Clamps to 9.2 V within nanoseconds, limiting stress on USB controller's 5.5 V absolute maximum rating and enabling >10,000-event endurance. |
Use Scenario: Primary surge suppression on twisted-pair DSL lines exposed to lightning-induced surges in outdoor telecom cabinets. IC Role / Device Role / Timing Role: High-energy bidirectional clamp installed differential-mode across tip/ring, upstream of line driver ICs. Use Value: Handles 1500 W peak pulses per ITU-T K.20/K.21 standards, with 75 °C/W RθJA enabling operation at 70 °C ambient without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0CAHE3_A/H | Lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 110 °C/W) | Suitable only for lower-energy transients (e.g., IEC 61000-4-2), not IEC 61000-4-5 Level 4 | Select when board space is constrained and surge threat level is limited to ESD or low-energy switching noise. |
| SMCJ5.0CAHE3_A/I | Same electrical specs and SMC package, but RoHS-compliant commercial grade (E3) instead of halogen-free (HM3) | Lacks halogen-free certification required by Tier 1 automotive customers and some industrial OEMs | Choose for cost-sensitive non-automotive designs where halogen-free compliance is not mandated. |
Compared with SMCJ5.0CAHM3_A/I, SMAJ5.0CAHE3_A/H trades surge capacity and thermal performance for size reduction, while SMCJ5.0CAHE3_A/I retains full electrical equivalence but omits halogen-free assurance-making the HM3 variant essential for automotive AEC-Q101 deployments requiring full material compliance.

FAQ
What does the "CA" suffix indicate in SMCJ5.0CAHM3_A/I?
The "CA" suffix in SMCJ5.0CAHM3_A/I denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression for both positive and negative polarity surges. Unlike unidirectional variants (e.g., SMCJ5.0A), SMCJ5.0CAHM3_A/I has no cathode band marking and exhibits identical VBR, VC, and IPPM characteristics in either direction-critical for AC-coupled or floating signal line protection.
Is SMCJ5.0CAHM3_A/I qualified for automotive use?
Yes, SMCJ5.0CAHM3_A/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code structure (HM3 suffix) and documentation reference to AEC-Q101 in the mechanical data section. This qualification covers stress tests including temperature cycling, humidity bias, and high-temperature operating life-ensuring suitability for under-hood and ECU applications where reliability under thermal and vibration stress is mandatory.
What is the maximum clamping voltage of SMCJ5.0CAHM3_A/I at rated surge current?
The maximum clamping voltage (VC) of SMCJ5.0CAHM3_A/I is 9.2 V at 163 A peak pulse current (IPPM), measured under the standardized 10/1000 µs double-exponential surge waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is validated per ANSI/IEEE C62.35 standards cited in the datasheet.
How does the HM3 suffix differ from E3 or HE3 in SMCJ5.0CAHM3_A/I?
The HM3 suffix in SMCJ5.0CAHM3_A/I specifies halogen-free, RoHS-compliant construction meeting Vishay's material categorization standard (doc?99912), whereas E3 denotes standard RoHS compliance and HE3 adds AEC-Q101 qualification without halogen-free assurance. HM3 satisfies strict environmental mandates from automotive OEMs and industrial regulators that prohibit brominated flame retardants-even when RoHS compliance alone would otherwise suffice.
Can SMCJ5.0CAHM3_A/I be used in place of a unidirectional TVS like SMCJ5.0A?
No-SMCJ5.0CAHM3_A/I is strictly bidirectional and lacks polarity marking, making it unsuitable as a direct replacement for unidirectional SMCJ5.0A in circuits requiring forward conduction or DC-biased clamping. Substituting it in such roles may cause unintended conduction during normal operation. Use only where symmetrical AC/DC transient suppression is required, such as across differential signal pairs or floating power domains.
