Product details
Overview
1.5SMC130CAHM3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, rated for 130 V breakdown voltage (VBR = 124–137 V at IT = 1 mA), 1500 W peak pulse power (10/1000 μs), and clamping voltage of 179 V at IPPM. It protects sensitive signal lines and power rails in automotive sensor units, industrial control interfaces, and telecom surge-prone circuits.
For engineers reviewing the 1.5SMC130CAHM3_A/I datasheet, 1.5SMC130CAHM3_A/I pinout, 1.5SMC130CAHM3_A/I application, or 1.5SMC130CAHM3_A/I equivalent, this device delivers AEC-Q101 qualification, halogen-free RoHS compliance, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive and industrial PCB designs requiring robust ESD and lightning transient immunity.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR, VC, and IPPM specifications in forward and reverse directions. Its glass-passivated junction ensures stable leakage (<1 μA at VWM = 111 V) and fast response time (<1.0 ns), enabling protection of high-speed data lines without signal distortion.
Thermally, it features RθJA = 75 °C/W and RθJL = 15 °C/W, supporting operation up to TJ = 150 °C. The device is rated for repetitive 10/1000 μs surges at 0.01% duty cycle and meets UL 497B recognition (QVGQ2) for protector classification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 124 V / 137 V at IT = 1 mA - defines precise clamping onset threshold for bidirectional overvoltage events |
| VWM | 111 V - maximum continuous reverse stand-off voltage before leakage exceeds 1 μA |
| VC @ IPPM | 179 V at 8.4 A - clamped voltage during 1500 W transient, limiting downstream IC stress |
| PPPM | 1500 W (10/1000 μs waveform) - peak surge energy handling capacity for lightning and inductive switching transients |
| IPPM | 8.4 A - peak pulse current capability under standardized surge waveform |

Use Scenario: Secondary-side clamping on 12 V or 24 V DC input rails of embedded controllers subjected to inductive kickback from solenoids or relays. IC Role / Device Role / Timing Role: Parallel-connected bidirectional suppressor across rail-to-ground, absorbing energy before LDO or DC/DC converter input. Use Value: 1500 W rating handles repetitive 10/1000 μs transients without degradation - extends system uptime in harsh industrial settings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | Lower PPPM = 600 W; same VBR range but SMB package (smaller footprint, higher RθJA) | Limited to lower-energy transients; unsuitable for automotive load dump or telecom lightning tests | Select when board space is constrained and surge energy is ≤600 W |
| 1.5KE130CA | Through-hole DO-201 package; identical electrical specs but higher thermal resistance (RθJA ≈ 100 °C/W) | Not suitable for automated SMT assembly; requires wave soldering and larger PCB real estate | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with SMBJ130CA and 1.5KE130CA, the 1.5SMC130CAHM3_A/I uniquely combines AEC-Q101 qualification, halogen-free compliance, SMC package thermal performance (RθJL = 15 °C/W), and full 1500 W surge rating - making it the preferred choice for production automotive and industrial SMT applications demanding long-term reliability and regulatory alignment.

FAQ
What is the clamping voltage of the 1.5SMC130CAHM3_A/I under maximum rated surge current?
The 1.5SMC130CAHM3_A/I clamps to 179 V at its peak pulse current (IPPM) of 8.4 A, measured using the standardized 10/1000 μs double-exponential waveform. This value is guaranteed per Vishay's datasheet (Document Number: 88303, Rev. 09-Mar-2026) and defines the upper voltage limit imposed on protected circuitry during worst-case transients. Designers must verify that downstream components tolerate this clamped voltage with appropriate safety margin.
Is the 1.5SMC130CAHM3_A/I suitable for automotive applications?
Yes, the 1.5SMC130CAHM3_A/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant, and automotive-grade construction. It has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and mechanical shock per JESD22 standards. Its 150 °C maximum junction temperature and UL 497B recognition further validate its suitability for under-hood and body-control module deployments.
What does the "CA" suffix mean in 1.5SMC130CAHM3_A/I?
The "CA" suffix in 1.5SMC130CAHM3_A/I denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., "A"), the CA version has no cathode band marking and exhibits identical VBR, VC, and IPPM characteristics in either polarity, making it ideal for AC-coupled or differential signal line protection.
What is the moisture sensitivity level (MSL) rating for the 1.5SMC130CAHM3_A/I?
The 1.5SMC130CAHM3_A/I is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ambient conditions ≤30 °C and ≤85% relative humidity. No baking or dry-pack handling is required prior to reflow soldering, simplifying manufacturing logistics and reducing risk of popcorning or delamination during assembly.
How does the 1.5SMC130CAHM3_A/I compare to the 1.5SMC130A variant?
The 1.5SMC130CAHM3_A/I is bidirectional and AEC-Q101 qualified with halogen-free construction, whereas the 1.5SMC130A is unidirectional, commercial-grade, and lacks automotive qualification. Electrically, both share identical VBR (124–137 V) and VC (179 V), but the CA version supports symmetrical clamping and is validated for automotive temperature and lifetime requirements - critical for functional safety-critical systems.
