Product details
Overview
1.5SMC130CA-M3/57T from Vishay General Semiconductor is a bidirectional 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, industrial I/O modules, and telecom line protection.
For engineers reviewing the 1.5SMC130CA-M3/57T datasheet, 1.5SMC130CA-M3/57T pinout, 1.5SMC130CA-M3/57T application, or 1.5SMC130CA-M3/57T equivalent, this page delivers verified electrical parameters, SMC (DO-214AB) package details, bidirectional clamping behavior, thermal resistance (RθJA = 75 °C/W), and AEC-Q101-qualified alternatives for automotive-grade design validation.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping performance regardless of transient polarity - critical for protecting AC-coupled or floating signal paths. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 μA at 111 V), while the low incremental surge resistance enables tight voltage control during high-energy transients.
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 achieves specified thermal derating per Figure 2, and its MSL Level 1 rating confirms suitability for standard reflow processes up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 111 V - maximum continuous reverse voltage before clamping initiates; defines safe operating margin below system rail. |
| VBR (Breakdown Voltage) | 124–137 V at 1 mA - precise voltage threshold where avalanche conduction begins; ensures predictable turn-on timing. |
| VC (Clamping Voltage) | 179 V at IPPM = 8.4 A - peak voltage seen by protected circuit during 10/1000 μs transient; determines stress on downstream ICs. |
| PPPM | 1500 W - peak transient energy absorption capacity under standardized 10/1000 μs waveform; validates surge immunity level. |
| RθJA | 75 °C/W - thermal resistance from junction to ambient; used to calculate max allowable power dissipation at elevated ambient temperatures. |
| TJ max | +150 °C - maximum junction temperature; sets upper limit for thermal design and reliability modeling in sealed enclosures. |
| ID (Leakage) | <1 μA at VWM - ultra-low reverse leakage preserves signal integrity and minimizes standby power loss in high-impedance nodes. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, MSL Level 1. Dimensions: 7.75 mm × 6.22 mm × 2.62 mm (L × W × H); matte tin-plated leads solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; symmetrical with cathode in bidirectional operation | Enables clamping in both directions - no polarity marking required; connects to either side of protected line without orientation concern. |
| Cathode | Current exit terminal in forward bias; electrically identical to anode for bidirectional devices | Provides matched avalanche response for positive and negative transients - eliminates need for dual-device placement in differential or AC paths. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping symmetry | Identical VBR (124–137 V) and VC (179 V) in both polarities - simplifies layout for floating or AC-coupled interfaces like RS-485 or CAN bus stubs. |
| 1500 W peak pulse power | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-earth, 2 kV line-line) when properly mounted - meets industrial and automotive surge immunity requirements. |
| Glass-passivated junction | Ensures stable, repeatable breakdown voltage over lifetime and temperature - critical for long-term reliability in unattended equipment. |
| MSL Level 1 rating | Compatible with standard Pb-free reflow profiles (peak 260 °C) without baking - reduces manufacturing complexity and cost. |
| AEC-Q101 qualification option | HM3 suffix variants are AEC-Q101 qualified - enables use in automotive powertrain and body electronics where component validation is mandatory. |

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-M3/57T | Lower PPPM (600 W), same VWM/VC, SMB package (smaller footprint, higher RθJA = 100 °C/W) | Preferred for space-constrained consumer PCBs where surge energy is limited to IEC 61000-4-5 Level 2 | Select when board area is critical and peak transient energy does not exceed 600 W - verify thermal margin with reduced copper pad area. |
| 1.5KE130CA-E3/54 | Through-hole DO-201 package, identical VWM/VC/PPPM, higher IFSM (200 A), but no AEC-Q101 option | Suitable for legacy industrial power supplies requiring manual assembly or high-reliability through-hole mounting | Choose for repair/refurbishment of existing through-hole designs or where automated SMT placement is unavailable. |
Compared with 1.5SMC130CA-M3/57T, SMBJ130CA-M3/57T trades surge capacity for compactness, while 1.5KE130CA-E3/54 retains full power handling but sacrifices SMT compatibility and automotive qualification - guiding selection based on mechanical constraints, thermal budget, and compliance needs.

FAQ
What is the clamping voltage of the 1.5SMC130CA-M3/57T under a 10/1000 μs surge?
The 1.5SMC130CA-M3/57T clamps to a maximum of 179 V when subjected to an 8.4 A peak pulse current with a 10/1000 μs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 8.0 mm × 8.0 mm copper pads) and defines the upper voltage limit imposed on protected circuitry during surge events. The 1.5SMC130CA-M3/57T maintains this clamping performance symmetrically in both directions due to its bidirectional construction.
Is the 1.5SMC130CA-M3/57T AEC-Q101 qualified?
No - the 1.5SMC130CA-M3/57T uses the M3 suffix indicating halogen-free, RoHS-compliant commercial grade construction, but it is not AEC-Q101 qualified. For automotive-qualified versions, select the HM3 suffix variant (e.g., 1.5SMC130CAHM3_A/H), which carries full AEC-Q101 certification and is designated for powertrain and body electronics applications. The 1.5SMC130CA-M3/57T remains suitable for industrial and consumer applications requiring robust transient suppression without automotive qualification.
What is the standoff voltage (VWM) and how does it relate to system operating voltage?
The 1.5SMC130CA-M3/57T has a standoff voltage (VWM) of 111 V - the maximum DC or RMS voltage that can be continuously applied without triggering clamping. This value must exceed the system's normal operating voltage (e.g., 96 V for a 12 V automotive system under load dump) with sufficient margin to avoid false triggering. The 1.5SMC130CA-M3/57T is commonly used on 72–96 V nominal rails where transient margins require ≥111 V VWM to ensure reliable non-conduction during steady-state operation.
Can the 1.5SMC130CA-M3/57T be used in unidirectional configurations?
No - the "CA" suffix explicitly denotes a bidirectional device, meaning it provides symmetrical clamping for both positive and negative transients. Unidirectional variants use the "A" suffix (e.g., 1.5SMC130A-M3/57T) and feature a cathode band for polarity-sensitive placement. Using the 1.5SMC130CA-M3/57T in place of a unidirectional TVS would result in correct clamping behavior but unnecessary duplication of function in DC-biased circuits; always match suffix to application polarity requirements.
What is the thermal resistance and how does it affect power derating?
The 1.5SMC130CA-M3/57T 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 pads. This value directly governs power derating: for example, at 70 °C ambient, the maximum allowable continuous power dissipation drops to approximately 0.107 W ((150 °C − 70 °C) / 75 °C/W). The 1.5SMC130CA-M3/57T is intended for transient, not continuous, power dissipation - its 6.5 W PD rating applies only under infinite heatsink conditions and is not relevant for surge duty cycles.
