Product details
Overview
SMCJ130CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection of DC power rails and signal lines. It features a 130 V standoff voltage (VWM), 209 V maximum clamping voltage (VC) at 7.2 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O modules.
For engineers reviewing the SMCJ130CAHM3/I datasheet, SMCJ130CAHM3/I pinout, SMCJ130CAHM3/I application, or SMCJ130CAHM3/I equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification status, halogen-free RoHS compliance (HM3 suffix), and thermal resistance (RθJA = 75 °C/W) under standard PCB pad layout.
Technical Context
This device operates as a voltage-clamped crowbar during transient overvoltage events, leveraging an avalanche breakdown junction to divert surge current away from protected circuitry. Its bidirectional structure ensures symmetrical clamping in both polarities without polarity marking, and its glass-passivated chip junction enables stable breakdown characteristics across temperature.
The SMCJ130CAHM3/I is rated for -55 °C to +150 °C operating junction temperature, supports 200 A unidirectional surge current (IFSM) - though not applicable here due to bidirectional configuration - and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak temperature tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - maximum continuous reverse standoff voltage before clamping begins; defines upper limit of normal operating voltage on protected line |
| VBR min/max | 144 V / 159 V at IT = 1 mA - verified breakdown voltage range ensuring reliable turn-on margin above VWM |
| VC @ IPPM | 209 V at 7.2 A - clamping voltage under 10/1000 μs surge; determines worst-case overvoltage seen by downstream ICs |
| PPPM | 1500 W - peak pulse power handling capability; defines energy absorption capacity for standardized lightning/surge transients |
| ID @ VWM | 1.0 μA - maximum reverse leakage at 130 V; negligible loading on 12–48 V DC systems |
| TJ max. | +150 °C - maximum junction temperature; enables operation in under-hood automotive or enclosed industrial enclosures |
| RθJA | 75 °C/W - thermal resistance junction-to-ambient on standard 8 mm × 8 mm copper pads; informs derating above 25 °C ambient |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional - no polarity marking; terminals are matte tin-plated leads solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode / Anode (symmetrical) | Bidirectional avalanche junction node | Both terminals function identically; no cathode band - enables placement without orientation check in automated assembly |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - required for engine control, ADAS sensor, and infotainment power rail protection |
| Halogen-free & RoHS-compliant (HM3) | Meets IEC 61249-2-21 and JEDEC J-STD-203; eliminates brominated flame retardants for safer end-of-life processing and regulatory compliance |
| Low incremental surge resistance | Enables tighter clamping (VC/VBR ratio = 1.45) versus legacy TVS devices - reduces stress on downstream MOSFET gate drivers and ADC front-ends |
| MSL Level 1 moisture sensitivity | No dry-pack or baking required prior to reflow; compatible with standard SMT production lines using 260 °C peak profile |
| Very fast response time (< 1 ps) | Clamps transients before propagation into sensitive analog or digital circuitry - critical for CAN FD, LIN, and isolated RS-485 interfaces |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130CAHE3/A | Same VWM (130 V) and VC (209 V), but lower PPPM (400 W); SOD-123 package (smaller footprint, higher RθJA = 110 °C/W) | Not suitable for 1500 W surge environments; limited to low-energy signal-line protection | Select only when board space is constrained and surge threat level is ≤400 W (e.g., USB or UART lines) |
| 1.5KE130CA | Through-hole DO-201 package; identical electrical specs (VWM = 130 V, VC = 209 V, PPPM = 1500 W), but no AEC-Q101 or MSL Level 1 rating | Excludes automotive and high-reliability SMT production; requires wave soldering or hand assembly | Use only in non-automotive, non-reflow applications where manual assembly or legacy through-hole design is mandated |
Compared with SMAJ130CAHE3/A and 1.5KE130CA, the SMCJ130CAHM3/I uniquely combines 1500 W surge capability, AEC-Q101 qualification, halogen-free compliance, and MSL Level 1 suitability - making it the only choice for high-volume automotive SMT production requiring full regulatory alignment and thermal performance on standard pads.

FAQ
What does the "HM3" suffix indicate in SMCJ130CAHM3/I?
The HM3 suffix in SMCJ130CAHM3/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It confirms compliance with JEDEC J-STD-203 for halogen content and inclusion in Vishay's automotive-qualified product line - essential for use in engine control units, ADAS sensors, and other safety-critical automotive subsystems. The "I" indicates 13-inch tape-and-reel packaging (3500 units per reel).
Is SMCJ130CAHM3/I suitable for protecting CAN bus lines?
Yes, SMCJ130CAHM3/I is suitable for protecting CAN bus power rails (e.g., VCC supply to CAN transceivers) but not the differential data lines themselves due to its 209 V clamping voltage. For CAN_H/CAN_L signal line protection, lower-voltage TVS devices such as SMBJ12CA or D3V3F4U2LP are recommended. The SMCJ130CAHM3/I excels at safeguarding the 12 V or 24 V supply feeding the CAN interface IC against load dump and ISO 7637-2 transients.
How does the bidirectional configuration of SMCJ130CAHM3/I affect PCB layout?
The bidirectional configuration of SMCJ130CAHM3/I eliminates polarity marking - there is no cathode band, and both terminals are functionally identical. This allows unrestricted orientation during automated placement, reducing placement errors and eliminating orientation verification steps in AOI inspection. Layout requires symmetric 8 mm × 8 mm copper pads per terminal per Vishay's recommended footprint to achieve specified thermal and surge performance.
What is the maximum allowable ambient temperature for continuous operation of SMCJ130CAHM3/I?
SMCJ130CAHM3/I has a maximum junction temperature (TJ max.) of +150 °C and a thermal resistance RθJA of 75 °C/W on standard 8 mm × 8 mm pads. At 6.5 W steady-state power dissipation (PD), the maximum ambient temperature for continuous operation is approximately +103 °C - calculated as TJ max. − (PD × RθJA). Derating curves in Figure 2 of the datasheet must be applied for operation above 25 °C ambient to maintain reliability.
Does SMCJ130CAHM3/I meet UL 497B recognition?
Yes, SMCJ130CAHM3/I is Underwriters Laboratories (UL) recognized under standard UL 497B for protectors, with file number E136766. This applies to both unidirectional and bidirectional variants in the SMCJ family. UL 497B recognition validates its suitability for use in telecommunications and data line protection applications where third-party safety certification is required for system-level compliance.
