Product details
Overview
SMCJ130CA-M3/57T 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 (PPPM) with 10/1000 μs waveform - deployed in automotive power line and industrial sensor interface protection.
For engineers reviewing the SMCJ130CA-M3/57T datasheet, SMCJ130CA-M3/57T pinout, SMCJ130CA-M3/57T application, or SMCJ130CA-M3/57T equivalent, this part delivers verified bidirectional surge suppression with halogen-free RoHS compliance, AEC-Q101 qualification readiness, and MSL Level 1 moisture sensitivity - critical for high-reliability board-level ESD and lightning transient hardening.
Technical Context
The SMCJ130CA-M3/57T operates as a bidirectional avalanche diode, symmetrically clamping voltage transients in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance, enabling fast response to sub-microsecond transients induced by inductive switching or ESD events.
Designed for surface-mount automated placement, it uses the SMC (DO-214AB) package with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. Thermal resistance is 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-lead), supporting operation from –55 °C to +150 °C junction temperature.

Applications
| Automotive Power Line Protection | Industrial Sensor Interface |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs against load dump and alternator transients per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Primary bidirectional clamping device placed at main power input, upstream of DC-DC converters and microcontrollers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC130CA-13-F | Same VWM (130 V) and VC (209 V), but lower PPPM (1000 W); SOD-123FL package (smaller footprint, higher RθJA) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a or IEC 61000-4-5 Level 4 | Select only for space-constrained consumer IoT nodes where surge threat level is limited to IEC 61000-4-2 ESD only. |
| 1.5KE130CA | Same electrical specs (VWM = 130 V, VC = 209 V, PPPM = 1500 W), but axial DO-201 package - larger size, manual assembly, higher inductance | Not suitable for high-frequency or high-density PCB layouts; thermal performance inferior due to lack of SMD thermal pad coupling | Choose only for legacy through-hole designs or prototyping where rework flexibility outweighs density and thermal needs. |
Compared with SAC130CA-13-F and 1.5KE130CA, the SMCJ130CA-M3/57T uniquely combines 1500 W surge capacity, SMC package thermal efficiency (RθJA = 75 °C/W), and halogen-free M3 compliance - making it the optimal choice for volume automotive and industrial SMT production requiring AEC-Q101 alignment and IPC-A-610 Class 3 reliability.

FAQ
What is the clamping voltage of the SMCJ130CA-M3/57T under a 10/1000 μs surge?
The SMCJ130CA-M3/57T clamps to a maximum of 209 V when subjected to its rated peak pulse current of 7.2 A with a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 standards and confirmed in Vishay's datasheet revision 09-Jan-2024 (Document Number: 88394). The clamping voltage directly determines the maximum stress imposed on downstream components during surge events, making it a critical parameter for system-level overvoltage margin analysis in the SMCJ130CA-M3/57T design-in process.
Is the SMCJ130CA-M3/57T suitable for automotive applications?
Yes - the SMCJ130CA-M3/57T is manufactured using Vishay's automotive-grade process flow. While the base M3 suffix denotes halogen-free RoHS compliance, the HM3 variant (e.g., SMCJ130CA-HM3/57T) is explicitly AEC-Q101 qualified. The SMCJ130CA-M3/57T shares identical electrical and thermal specifications with the HM3 version and is widely used in automotive body control modules, power distribution units, and infotainment power supplies where AEC-Q101 testing is performed at the lot level. Its 150 °C TJ max and robust surge rating make the SMCJ130CA-M3/57T appropriate for under-hood and chassis-mounted systems.
How does the bidirectional configuration of the SMCJ130CA-M3/57T affect PCB layout?
The SMCJ130CA-M3/57T has no polarity marking and functions identically in both directions, eliminating orientation constraints during automated placement. This simplifies PCB layout for AC-coupled or floating signal paths such as RS-485, CAN FD, or Ethernet differential pairs - no need to verify anode/cathode alignment. However, thermal design remains critical: the datasheet mandates 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal to achieve rated 1500 W PPPM. Layouts must maintain symmetric trace geometry and avoid stubs to preserve high-frequency surge impedance matching in the SMCJ130CA-M3/57T installation.
What is the leakage current specification for the SMCJ130CA-M3/57T at its standoff voltage?
At its maximum working voltage of 130 V (VWM), the SMCJ130CA-M3/57T exhibits a maximum reverse leakage current (ID) of 1.0 μA at 25 °C. This ultra-low leakage ensures negligible power loss in always-on systems and prevents false triggering or signal distortion in high-impedance sensor or reference circuits. Leakage remains below 5.0 μA up to +125 °C, supporting reliable operation across the full industrial temperature range - a key differentiator versus lower-cost TVS diodes with ID > 10 μA at VWM, which can degrade accuracy in precision analog SMCJ130CA-M3/57T implementations.
Can the SMCJ130CA-M3/57T replace older 1.5KE series TVS diodes?
The SMCJ130CA-M3/57T matches the electrical performance of the 1.5KE130CA (same VWM = 130 V, VC = 209 V, PPPM = 1500 W) but offers superior thermal and mechanical integration. Unlike the axial DO-201 packaged 1.5KE130CA, the SMCJ130CA-M3/57T uses the SMC (DO-214AB) surface-mount package with lower parasitic inductance and direct copper-pad thermal coupling - improving high-frequency transient response and power dissipation. Replacement requires PCB redesign to accommodate the SMC footprint, but delivers measurable gains in surge robustness and manufacturing scalability for the SMCJ130CA-M3/57T in new designs.
