Product details
Overview
SMCJ130CAHM3/H 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 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 dissipation (10/1000 µs waveform), making it suitable for automotive power line and industrial sensor interface protection.
For engineers reviewing the SMCJ130CAHM3/H datasheet, SMCJ130CAHM3/H pinout, SMCJ130CAHM3/H application, or SMCJ130CAHM3/H equivalent, key selection criteria include bidirectional surge capability, AEC-Q101 qualification, halogen-free RoHS compliance, and compatibility with 8.0 mm × 8.0 mm copper pad layouts per JEDEC standards.
Technical Context
This device operates as a voltage-clamping protector using an avalanche breakdown mechanism, with symmetrical bidirectional behavior enabling suppression of both positive and negative transients without polarity sensitivity. Its low incremental surge resistance and fast response time (<1 ns) ensure effective suppression of ESD, lightning-induced surges, and inductive switching spikes.
The SMCJ130CAHM3/H is rated for continuous operation from −55 °C to +150 °C junction temperature and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its halogen-free, matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability requirements and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum reverse standoff voltage before clamping begins; defines operating margin below breakdown. |
| VBR min/max | 144 V / 159 V at 1 mA - Verified breakdown threshold range ensuring reliable turn-on during overvoltage events. |
| VC @ IPPM | 209 V at 7.2 A - Clamped voltage under 10/1000 µs surge; determines protected circuit's maximum stress level. |
| PPPM | 1500 W - Peak pulse power handling capacity; enables protection against high-energy transients like ISO 7637-2 Pulse 5a. |
| TJ max | +150 °C - Maximum junction temperature; supports under-hood automotive and high-ambient industrial deployment. |
| RθJA | 75 °C/W - Thermal resistance junction-to-ambient on standard 8.0 mm × 8.0 mm pads; informs thermal derating above 25 °C. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional configuration with no polarity marking. Case dimensions: 7.75 mm × 6.22 mm × 2.62 mm (L × W × H); terminals are matte tin-plated leads compatible with lead-free reflow.
| Pin/Terminal | Circuit Role | Design Meaning |

IC Role / Device Role / Timing Role: Bidirectional shunt protector on differential or single-ended signal lines connected to microcontroller ADC inputs. Use Value: Clamps ±15 kV contact ESD (IEC 61000-4-2) within nanoseconds while adding <1 pF capacitance at 0 V bias. |
| Telecom Surge Protection | Consumer Power Adapter Input |
|

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/VC, but lower PPPM (400 W) and smaller SMA package (DO-214AC); not AEC-Q101 qualified. | Limited to low-energy consumer or non-automotive industrial use; unsuitable for load dump or high-reliability environments. | Select only when space-constrained and surge energy is ≤400 W; verify thermal derating on reduced pad area. |
| SMCJ130AHE3/H | Unidirectional version with identical VWM, VC, and PPPM; includes cathode band marking and 3.5 V forward voltage at 100 A. | Requires polarity-aware layout; appropriate for DC-biased rails where negative transients are absent or blocked. | Choose when protecting unidirectional DC paths (e.g., 5 V logic rails) and polarity can be controlled in PCB routing. |
Compared with SMAJ130CAHE3/A and SMCJ130AHE3/H, the SMCJ130CAHM3/H uniquely combines bidirectional operation, 1500 W surge rating, AEC-Q101 qualification, and halogen-free construction-making it the only option validated for automotive-grade bidirectional rail protection under full ISO 7637-2 compliance.

FAQ
What does the "CA" suffix indicate in SMCJ130CAHM3/H?
The "CA" suffix in SMCJ130CAHM3/H denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., SMCJ130A), the SMCJ130CAHM3/H has no polarity marking and functions identically in either direction-critical for AC-coupled lines, floating sensors, or differential buses where voltage polarity is undefined.
Is SMCJ130CAHM3/H qualified for automotive applications?
Yes, SMCJ130CAHM3/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code structure ("HM3" indicates halogen-free, RoHS-compliant, and AEC-Q101–qualified). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD-ensuring reliability in automotive powertrain, body electronics, and ADAS modules operating from −40 °C to +125 °C ambient.
How does the clamping voltage of SMCJ130CAHM3/H compare to its standoff voltage?
The SMCJ130CAHM3/H has a standoff voltage (VWM) of 130 V and a maximum clamping voltage (VC) of 209 V at 7.2 A peak pulse current. This 79 V margin ensures that normal operating voltages remain well below breakdown, while still limiting surge-induced stress on downstream components to a predictable, safe ceiling-essential for protecting 150 V-rated capacitors or 200 V MOSFETs in 24 V systems.
What is the thermal performance of SMCJ130CAHM3/H on standard PCB pads?
When mounted on the recommended 8.0 mm × 8.0 mm copper pads per terminal, SMCJ130CAHM3/H exhibits a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W. This allows sustained 6.5 W power dissipation at 50 °C ambient, and supports derated surge handling up to 1500 W for short pulses-provided board layout follows Vishay's pad recommendations and avoids thermal bottlenecks in copper pours.
Can SMCJ130CAHM3/H replace unidirectional TVS diodes in existing designs?
SMCJ130CAHM3/H can replace unidirectional TVS diodes like SMCJ130AHE3/H only if the circuit topology permits bidirectional clamping-such as across floating signal pairs, transformer-coupled lines, or AC rails. It must not be substituted in DC-biased unidirectional paths without verifying that reverse leakage and forward conduction do not interfere with system biasing, as the SMCJ130CAHM3/H lacks a defined cathode/anode orientation.
