Product details
Overview
1.5SMC130CA-M3/9AT from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 130 V standoff voltage (VWM), 179 V clamping voltage (VC) at 8.4 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O modules.
For engineers reviewing the 1.5SMC130CA-M3/9AT datasheet, 1.5SMC130CA-M3/9AT pinout, 1.5SMC130CA-M3/9AT application, or 1.5SMC130CA-M3/9AT equivalent, key selection criteria include bidirectional clamping performance, SMC (DO-214AB) package compatibility, AEC-Q101 qualification status, and thermal resistance (RθJL = 15 °C/W) for high-reliability PCB layouts.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping behavior during positive and negative transients. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the low incremental surge resistance enables rapid energy diversion without thermal runaway.
The device is rated for repetitive 10/1000 μs surges at 0.01% duty cycle and supports operation from −65 °C to +150 °C junction temperature. Mounting on 8.0 mm × 8.0 mm copper pads per terminal ensures effective thermal dissipation under sustained transient stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 111 V - Maximum continuous reverse voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 124–137 V at 1 mA - Confirmed breakdown range ensures predictable turn-on during fast transients. |
| VC (Clamping) | 179 V at IPPM = 8.4 A - Peak voltage seen by protected circuit during 10/1000 μs surge; critical for downstream IC survival. |
| PPPM | 1500 W - Peak pulse power handling capacity; determines survivability against lightning-induced or inductive-switching surges. |
| RθJL | 15 °C/W - Junction-to-leads thermal resistance; enables accurate thermal modeling when mounted on standard PCB copper areas. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | Lower PPPM (600 W), same VWM/VC specs, SMB package (smaller footprint, higher RθJA = 100 °C/W) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 without derating | Select when board space is constrained and surge energy is ≤600 W; verify thermal margin under repeated stress. |
| 1.5KE130CA | Through-hole DO-201 package, identical electrical specs, higher mechanical robustness but no SMT compatibility | Requires wave soldering or hand assembly; not suitable for fully automated production | Choose for prototyping or legacy through-hole designs where rework tolerance and mechanical stability outweigh SMT benefits. |
Compared with SMBJ130CA and 1.5KE130CA, the 1.5SMC130CA-M3/9AT delivers full 1500 W surge capability in an SMT-optimized SMC package with superior thermal coupling (RθJL = 15 °C/W), making it the preferred choice for high-volume automotive and industrial applications requiring AEC-Q101-aligned reliability and automated assembly.

FAQ
What does the "CA" suffix indicate in 1.5SMC130CA-M3/9AT?
The "CA" suffix denotes a bidirectional configuration - meaning the 1.5SMC130CA-M3/9AT provides symmetrical transient voltage suppression for both positive and negative polarity surges. Unlike unidirectional variants (e.g., 1.5SMC130A), it has no cathode marking and functions identically in either direction, making it ideal for AC-coupled or floating signal paths where polarity is undefined.
Is 1.5SMC130CA-M3/9AT AEC-Q101 qualified?
The 1.5SMC130CA-M3/9AT itself is not AEC-Q101 qualified - the "M3" suffix indicates halogen-free, RoHS-compliant commercial-grade construction. However, Vishay offers AEC-Q101-qualified versions under ordering codes HM3_X (e.g., 1.5SMC130CAHM3_A/I), which share identical electrical specs but undergo additional automotive stress testing and traceability controls.
What is the clamping voltage of 1.5SMC130CA-M3/9AT at its rated peak pulse current?
The 1.5SMC130CA-M3/9AT has a maximum clamping voltage (VC) of 179 V when subjected to its rated peak pulse current (IPPM) of 8.4 A under the standard 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88303 and represents the upper limit of voltage imposed on the protected circuit during worst-case surge conditions.
Can 1.5SMC130CA-M3/9AT be used in place of a unidirectional TVS like 1.5SMC130A?
No - the 1.5SMC130CA-M3/9AT is strictly bidirectional and lacks polarity marking, while 1.5SMC130A is unidirectional with a defined cathode band. Substituting them requires verifying circuit topology: bidirectional use is mandatory for AC signals or floating grounds, whereas unidirectional parts are required for DC-biased lines where reverse leakage must be minimized during normal operation.
What PCB pad layout is recommended for optimal thermal performance of 1.5SMC130CA-M3/9AT?
Vishay specifies mounting the 1.5SMC130CA-M3/9AT on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal to achieve rated 1500 W pulse power and maintain junction temperature within limits. Smaller pads increase thermal resistance and risk premature failure under repetitive surges; thermal vias under pads further improve heat spreading in multilayer boards.
