Product details
Overview
1.5SMC130AHM3/H from Vishay General Semiconductor is a unidirectional 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 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 motor control inputs, and telecom line protection.
For engineers reviewing the 1.5SMC130AHM3/H datasheet, 1.5SMC130AHM3/H pinout, 1.5SMC130AHM3/H application, or 1.5SMC130AHM3/H equivalent, this device delivers AEC-Q101 qualification, halogen-free RoHS compliance, low incremental surge resistance, and fast response time critical for IEC 61000-4-5 surge immunity in harsh environments.
Technical Context
The 1.5SMC130AHM3/H operates as a unidirectional avalanche diode with glass-passivated junction, optimized for clamping transients above its 124–137 V breakdown range (tested at 1 mA). Its SMC (DO-214AB) package supports automated placement and meets MSL level 1 per J-STD-020 with 260 °C reflow peak.
It exhibits a maximum reverse leakage of 1.0 μA at 111 V standoff, a temperature coefficient of VBR at +0.107 %/°C, and thermal resistance of 75 °C/W (junction-to-ambient) on standard 8.0 mm × 8.0 mm copper pads - enabling reliable operation up to 150 °C junction temperature under repetitive surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Applications
| Automotive Sensor Protection | Industrial Motor Drive Inputs |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and chassis ground to clamp transients before reaching sensitive input pins. Use Value: Prevents latch-up or permanent damage to microcontroller ADC inputs and transceiver ESD structures during 12 V system load dump events. |
Use Scenario: Safeguarding PLC digital input modules connected to 24 V DC field wiring exposed to inductive kickback from solenoids and contactors. IC Role / Device Role / Timing Role: Standoff-clamp TVS installed across input terminals to shunt surge energy away from optocoupler input stages. Use Value: Maintains functional safety integrity by limiting transient voltage to <179 V, well below optocoupler isolation barrier rating (typically 5 kV). |
| Telecom Line Interface | Power Supply Input Stage |
Use Scenario: Front-end protection for Ethernet PHYs and RS-485 transceivers in outdoor base stations subjected to lightning-induced surges. IC Role / Device Role / Timing Role: First-stage clamping device on differential pair, coordinated with common-mode chokes and secondary GDTs. Use Value: Reduces let-through energy to downstream TVS arrays, extending overall system surge withstand to ≥10 kV (IEC 61000-4-5) |
Use Scenario: Secondary overvoltage protection on 110/220 V AC-DC converter DC bus against MOV failure or rectifier overshoot. IC Role / Device Role / Timing Role: Fast-acting unidirectional clamp parallel to bulk capacitor, triggered after primary MOV clamps. Use Value: Limits DC bus voltage spikes to ≤179 V, preventing overvoltage shutdown or electrolytic capacitor venting during line surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130A | Same VWM (111 V), lower PPPM (400 W), SMA package (smaller footprint, higher RθJA) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 | Select when board space is constrained and surge threat level is ≤1 kV |
| 1.5KE130A | Same VWM/VBR/VC specs, but axial DO-201AD package - not SMT-compatible | Requires through-hole assembly; incompatible with automated SMT lines | Choose only for legacy through-hole designs or manual repair scenarios |
Compared with SMAJ130A and 1.5KE130A, the 1.5SMC130AHM3/H uniquely combines 1500 W surge capability, AEC-Q101 qualification, halogen-free compliance, and SMC package - making it the only drop-in solution for high-reliability automotive and industrial SMT production requiring full IEC 61000-4-5 compliance.

FAQ
What is the clamping voltage of the 1.5SMC130AHM3/H under a 10/1000 μs surge?
The 1.5SMC130AHM3/H has a maximum clamping voltage (VC) of 179 V at 8.4 A peak pulse current (IPPM) under a 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88303 and defines the upper voltage limit imposed on protected circuitry during standardized surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the 1.5SMC130AHM3/H suitable for automotive applications?
Yes, the 1.5SMC130AHM3/H is AEC-Q101 qualified (denoted by the HM3 suffix) and specifically tested for automotive reliability including temperature cycling, high-temperature reverse bias, and ESD. It is approved for use in engine control units, body electronics, and ADAS sensor interfaces where sustained operation at 150 °C junction temperature and immunity to load dump transients are required - confirmed in Vishay's qualification report referenced in document 88303.
What does the "HM3" suffix indicate in 1.5SMC130AHM3/H?
The "HM3" suffix in 1.5SMC130AHM3/H signifies halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Per Vishay's ordering information table (page 3 of doc 88303), HM3 denotes both environmental compliance and automotive-grade reliability validation - distinct from commercial-grade M3 or HE3 variants. The "/H" denotes 7-inch tape-and-reel packaging with 850 units per reel.
How does the 1.5SMC130AHM3/H compare to bidirectional TVS diodes like 1.5SMC130CA?
The 1.5SMC130AHM3/H is unidirectional and intended for DC-biased lines where polarity is fixed (e.g., power rails, single-ended signals); it offers lower leakage (<1.0 μA) and avoids ambiguity in clamping direction. In contrast, 1.5SMC130CA is bidirectional and suited for AC or floating lines (e.g., data buses), but exhibits higher leakage and lacks cathode marking. The 1.5SMC130AHM3/H cannot substitute for 1.5SMC130CA in AC-coupled applications without circuit redesign.
What PCB layout guidance applies to the 1.5SMC130AHM3/H?
Vishay specifies mounting on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal to achieve rated 1500 W pulse power (Figure 2, doc 88303). Trace inductance must be minimized: keep leads short and wide, place the 1.5SMC130AHM3/H as close as possible to the protected port, and route the cathode directly to a low-impedance ground plane - deviations reduce effective clamping performance and may cause voltage overshoot exceeding 179 V.
