Product details
Overview
SMCJ130CAHM3_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 209 V at 7.2 A peak pulse current, with 1500 W peak pulse power rating and 130 V standoff voltage. It protects MOSFETs, ICs, and sensor signal lines in automotive powertrain control units, industrial motor drives, and telecom interface circuits.
For engineers reviewing the SMCJ130CAHM3_A/I datasheet, SMCJ130CAHM3_A/I pinout, SMCJ130CAHM3_A/I application, or SMCJ130CAHM3_A/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, halogen-free RoHS compliance, and thermal resistance of 75 °C/W junction-to-ambient under standard pad layout.
Technical Context
This device operates as a voltage-clamping protector using an avalanche breakdown mechanism. Its bidirectional symmetry enables suppression of both positive and negative transients without polarity sensitivity, and its glass-passivated junction ensures stable breakdown characteristics across temperature and life cycles.
The SMCJ130CAHM3_A/I delivers 1500 W peak pulse power handling per 10/1000 μs waveform, with clamping voltage VC = 209 V at IPPM = 7.2 A, and exhibits low incremental surge resistance for minimal voltage overshoot during fast ESD or lightning-induced surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 130 V - Maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown. |
| VBR (Breakdown Voltage) | 144 V min / 159 V max at IT = 1 mA - Ensures reliable conduction onset within tight tolerance band for predictable protection threshold. |
| VC (Clamping Voltage) | 209 V at IPPM = 7.2 A - Peak voltage seen by protected circuit during worst-case 10/1000 μs surge; critical for downstream component survivability. |
| PPPM (Peak Pulse Power) | 1500 W - Sustains high-energy transients such as ISO 7637-2 Pulse 5a without degradation when mounted on 8 mm × 8 mm copper pads. |
| ID (Reverse Leakage) | 1.0 μA max at VWM - Negligible standby current draw; avoids loading sensitive reference or bias networks. |
| TJ max | 150 °C - Enables operation in under-hood automotive environments and enclosed industrial enclosures without derating. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height; compatible with automated pick-and-place. |
Pinout & Package
SMCJ130CAHM3_A/I uses a two-terminal SMC (DO-214AB) package with no polarity marking for bidirectional operation. Both terminals are electrically symmetrical and interchangeable in circuit layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path | Either terminal conducts avalanche current during overvoltage events in either polarity; no cathode band marking required. |
| Case (body) | Thermal path | Plastic-molded body transfers heat to PCB copper pads; RθJA = 75 °C/W measured on 8 mm × 8 mm pads per JEDEC standards. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or differential signal lines without external polarity management. |
| AEC-Q101 qualified | Validated for automotive powertrain, chassis, and ADAS modules requiring zero-failure reliability under thermal cycling and vibration stress. |
| Halogen-free & RoHS-compliant | Meets IEC 61249-2-21 and JEDEC J-STD-020 MSL level 1, enabling lead-free reflow assembly without delamination risk. |
| Low clamping ratio (VC/VBR ≈ 1.39) | Minimizes overvoltage stress on protected ICs compared to higher-ratio suppressors, preserving timing margins in high-speed interfaces. |
| Fast response time (< 1 ps) | Activates before transient energy couples into sensitive nodes, preventing latch-up or gate oxide damage in MOSFET drivers. |
Applications
| Automotive Powertrain Control | Industrial Motor Drive Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CAHM3_A/I | Lower PPPM (600 W), same VWM/VC, SMB package (smaller footprint, higher RθJA = 110 °C/W) | Acceptable for lower-energy surges (e.g., IEC 61000-4-5 Level 2), not suitable for ISO 7637-2 Pulse 5a. | Select when board space is constrained and surge threat level is limited to ESD and minor inductive spikes. |
| SMCJ130AHE3_A/I | Unidirectional version, identical VWM/VC/PPPM, same SMC package, commercial-grade (non-AEC-Q101) | Requires correct polarity placement; unsuitable for AC or floating signal lines; lacks automotive qualification evidence. | Choose only for cost-sensitive non-automotive designs where polarity is fixed and AEC-Q101 is not mandated. |
Compared with SMCJ130CAHM3_A/I, SMBJ130CAHM3_A/I trades peak power headroom for compactness, while SMCJ130AHE3_A/I sacrifices bidirectionality and automotive qualification for lower unit cost-neither offers drop-in replacement capability without layout or compliance review.

FAQ
What is the clamping voltage of the SMCJ130CAHM3_A/I at its rated peak pulse current?
The SMCJ130CAHM3_A/I has a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current (IPPM) of 7.2 A under the standard 10/1000 μs waveform. This value is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the SMCJ130CAHM3_A/I suitable for automotive applications?
Yes, the SMCJ130CAHM3_A/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction with automotive-grade reliability validation. It is explicitly rated for use in engine control units, body electronics, and ADAS subsystems where sustained operation from −55 °C to +150 °C and immunity to mechanical shock/vibration are required.
How does the bidirectional configuration of the SMCJ130CAHM3_A/I affect circuit layout?
The SMCJ130CAHM3_A/I has no polarity marking and functions identically in either orientation, simplifying PCB layout for AC-coupled, differential, or floating signal paths. Unlike unidirectional TVS diodes, it eliminates the need for cathode alignment checks during assembly and supports symmetric placement across balanced lines such as RS-485 or CAN bus pairs.
What is the thermal resistance of the SMCJ130CAHM3_A/I, and how does it impact power dissipation?
The SMCJ130CAHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the recommended 8.0 mm × 8.0 mm copper pad layout. This allows continuous power dissipation up to 6.5 W at TA = 50 °C, but for transient suppression, the 1500 W peak rating applies only for short-duration pulses-not steady-state operation.
Does the SMCJ130CAHM3_A/I meet industry surge immunity standards?
Yes, the SMCJ130CAHM3_A/I is engineered to meet key surge immunity standards including ISO 7637-2 (Pulse 1, 2a, 3a/b, and 5a), IEC 61000-4-5 (Level 3–4), and SAE J1113-11. Its 1500 W peak pulse power rating and 209 V clamping voltage provide validated protection margins for these standardized test waveforms when applied per manufacturer-recommended layout guidelines.
