Product details
Overview
SMCJ13CAHM3/H 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 a 10/1000 µs waveform, 21.5 V maximum clamping voltage at 69.8 A peak pulse current, and 13 V standoff voltage - deployed in automotive sensor signal lines, industrial I/O protection, and DC power rail surge suppression.
For engineers reviewing the SMCJ13CAHM3/H datasheet, SMCJ13CAHM3/H pinout, SMCJ13CAHM3/H application, or SMCJ13CAHM3/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, halogen-free RoHS compliance, and compatibility with automated SMT assembly on 8 mm × 8 mm copper pads.
Technical Context
This device operates as a voltage-clamped avalanche diode, responding within <1 ps to transient overvoltages and maintaining low incremental surge resistance to limit voltage overshoot during ESD or load-switching events. Its bidirectional symmetry ensures identical electrical characteristics in both polarities, eliminating polarity-dependent design constraints.
Rated for -55 °C to +150 °C junction temperature, it leverages glass-passivated junction technology and meets MSL Level 1 per J-STD-020 with 260 °C peak reflow tolerance - enabling use in high-reliability automotive ECUs and industrial controllers where thermal cycling and long-term stability are critical.

| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
Pinout & Package
SMCJ13CAHM3/H uses the SMC (DO-214AB) package: a two-terminal surface-mount case with cathode/anode leads formed in gull-wing configuration. No polarity marking is present on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; reverse-bias reference for bidirectional clamping | Connected to line being protected - forms symmetrical clamping path with cathode |
| Cathode | Current exit terminal in forward bias; reverse-bias reference for bidirectional clamping | Connected to ground or common reference - completes low-impedance surge shunt path |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR, VC, and IPPM in both directions - eliminates need for polarity-aware layout |
| Halogen-free & RoHS-compliant | HM3 suffix indicates halogen-free molding compound meeting JEDEC J-STD-020 MSL Level 1 |
| Automated placement optimized | Low-profile SMC package with matte tin-plated leads compliant with J-STD-002 solderability |
| High surge robustness | Withstands 200 A non-repetitive forward surge (8.3 ms half-sine), supporting motor drive and relay switching |
| UL 94 V-0 rated compound | Molding material self-extinguishes within 10 seconds after flame removal - required for safety-critical enclosures |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from ISO 7637-2 pulse 1/2a/5a transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed between signal line and chassis ground to suppress ±200 V transients without polarity concern. Use Value: Maintains signal integrity below 21.5 V clamping threshold while surviving repeated 1500 W surges - extends sensor lifetime in harsh automotive environments. | Use Scenario: Shielding digital input modules in programmable logic controllers from inductive kickback when controlling solenoids or contactors. IC Role / Device Role / Timing Role: Parallel-connected TVS across input terminals to divert >1 kA surge currents away from optocoupler input stages. Use Value: Enables reliable operation under IEC 61000-4-4 level 4 (2 kV) fast transient bursts without latch-up or degradation. |
| DC Power Rail Surge Suppression | Telecom Line Interface Protection |
Use Scenario: Safeguarding 12 V/24 V DC power distribution networks in factory automation systems against load dump and alternator spikes. IC Role / Device Role / Timing Role: Mounted directly at power entry point to clamp transients before reaching downstream regulators and microcontrollers. Use Value: Limits peak rail voltage to ≤21.5 V during 10/1000 µs surges - prevents brownout resets and MOSFET gate oxide damage. | Use Scenario: Protecting Ethernet PHY interfaces and RS-485 transceivers in outdoor telecom cabinets exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Placed differential-mode across data pair and common-mode to ground to absorb induced common-mode transients. Use Value: Provides symmetric clamping with <1 ps response - preserves signal timing margins in 100 Mbps+ links while meeting GR-1089-CORE requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13CAHE3/A | Lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 110 °C/W) | Not suitable for >500 W surge environments; limited thermal margin in high-ambient designs | Select when board space is constrained and surge energy is ≤400 W |
| SMCJ13CA-E3/57T | Same electrical specs, but commercial-grade (non-AEC-Q101), RoHS-compliant E3 suffix | Lacks automotive qualification; not approved for under-hood or safety-critical ECU use | Select for cost-sensitive industrial or consumer applications without automotive reliability requirements |
Compared with SMCJ13CAHM3/H, SMAJ13CAHE3/A offers smaller size but reduced surge handling and thermal performance, while SMCJ13CA-E3/57T matches all electrical parameters but omits AEC-Q101 validation - making SMCJ13CAHM3/H the only choice for automotive-grade bidirectional TVS duty with halogen-free compliance.

FAQ
What does the 'HM3' suffix indicate in SMCJ13CAHM3/H?
The HM3 suffix in SMCJ13CAHM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It specifies that the device uses a halogen-free molding compound, meets JEDEC J-STD-020 MSL Level 1, and has passed automotive-grade stress testing - distinguishing it from commercial-grade variants like SMCJ13CA-E3/57T. This makes SMCJ13CAHM3/H appropriate for automotive under-hood applications where regulatory and reliability requirements are strict.
Is SMCJ13CAHM3/H unidirectional or bidirectional?
SMCJ13CAHM3/H is a bidirectional Transient Voltage Suppressor, confirmed by the 'CA' suffix in its part number and explicitly stated in Vishay's datasheet. Electrical characteristics - including breakdown voltage, clamping voltage, and peak pulse current - apply identically in both directions. Unlike unidirectional versions (e.g., SMCJ13A), it carries no cathode band marking and requires no polarity alignment during PCB placement.
What is the maximum clamping voltage of SMCJ13CAHM3/H at rated surge current?
The maximum clamping voltage (VC) of SMCJ13CAHM3/H is 21.5 V at 69.8 A peak pulse current (IPPM), measured under the standard 10/1000 µs double-exponential waveform. This value is guaranteed across the full operating temperature range (-55 °C to +150 °C) and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Does SMCJ13CAHM3/H require a heatsink for standard operation?
No, SMCJ13CAHM3/H does not require an external heatsink for standard transient suppression duty. Its thermal resistance junction-to-lead (RθJL) is 15 °C/W, and typical junction-to-ambient (RθJA) is 75 °C/W when mounted on minimum recommended 8.0 mm × 8.0 mm copper pads per terminal. Continuous power dissipation is limited to 6.5 W at TA = 50 °C; since TVS devices conduct only during transient events (ms duration), steady-state heating is negligible - heatsinking is unnecessary unless used in repetitive high-duty-cycle scenarios.
Can SMCJ13CAHM3/H replace SMCJ13A in an existing design?
SMCJ13CAHM3/H cannot be a direct drop-in replacement for unidirectional SMCJ13A due to fundamental polarity differences: SMCJ13A is unidirectional (cathode-marked, conducts only in reverse), while SMCJ13CAHM3/H is bidirectional (no marking, symmetrical conduction). Swapping them risks incorrect clamping behavior - especially in DC-coupled circuits. If bidirectional protection is required, verify layout compatibility (no polarity constraints); if unidirectional function is essential, retain SMCJ13A or select SMCJ13AHM3/H instead.
