Product details
Overview
1.5SMC130AHE3_A/I 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 (VC) at 8.4 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive ECUs, industrial motor drives, and telecom power supplies.
For engineers reviewing the 1.5SMC130AHE3_A/I datasheet, 1.5SMC130AHE3_A/I pinout, 1.5SMC130AHE3_A/I application, or 1.5SMC130AHE3_A/I equivalent, key selection criteria include clamping performance under repetitive surge stress, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This device operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its breakdown threshold (VBR = 124–137 V) to shunt transient energy away from downstream circuitry. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns).
Designed for surface-mount use in the SMC (DO-214AB) package, it supports high-reliability applications requiring MSL Level 1 moisture sensitivity rating and lead-free, RoHS-compliant matte tin plating per J-STD-002. The cathode band denotes polarity, critical for correct orientation in DC-biased protection paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 111 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin. |
| VBR (Breakdown) | 124–137 V at 1.0 mA - Voltage range where avalanche conduction initiates; tight tolerance enables predictable protection thresholds. |
| VC (Clamping) | 179 V at IPPM = 8.4 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines maximum stress on downstream ICs. |
| PPPM | 1500 W - Peak pulse power handling capacity; validates suitability for lightning-induced transients per IEC 61000-4-5. |
| ID (Leakage) | <1.0 μA at VWM - Ultra-low reverse leakage preserves efficiency in high-impedance sensing or battery-powered circuits. |
| TJ max | +150 °C - Maximum junction temperature; supports operation in under-hood automotive environments and enclosed industrial enclosures. |
| RθJA | 75 °C/W - Thermal resistance from junction to ambient; informs heatsinking requirements when operating near PD = 6.5 W limit. |

FAQ
What is the clamping voltage of the 1.5SMC130AHE3_A/I under a 10/1000 μs surge?
The 1.5SMC130AHE3_A/I has a maximum clamping voltage (VC) of 179 V at 8.4 A peak pulse current (IPPM) with 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 their absolute maximum ratings.
Is the 1.5SMC130AHE3_A/I AEC-Q101 qualified?
Yes, the 1.5SMC130AHE3_A/I is AEC-Q101 qualified, as confirmed by the "HE3" suffix and documentation in Vishay's 1.5SMC Series datasheet (Rev. 09-Mar-2026). This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge - making the 1.5SMC130AHE3_A/I suitable for automotive powertrain, body electronics, and ADAS modules.
What is the standoff voltage (VWM) of the 1.5SMC130AHE3_A/I?
The standoff voltage (VWM) of the 1.5SMC130AHE3_A/I is 111 V, representing the maximum continuous reverse voltage the device can block without entering avalanche conduction. This parameter ensures reliable operation under normal 12 V or 24 V automotive rail conditions while maintaining sufficient margin below the 124–137 V breakdown range - a key design factor for stable protection in DC-biased applications.
What package does the 1.5SMC130AHE3_A/I use, and what are its mounting requirements?
The 1.5SMC130AHE3_A/I uses the SMC (DO-214AB) surface-mount package, with mechanical dimensions specified in inches/mm on page 5 of Vishay document 88303. It requires mounting on minimum 8.0 mm × 8.0 mm copper pads per terminal to achieve rated 1500 W pulse power and thermal performance - deviation reduces IPPM derating and risks thermal runaway during repeated surges.
How does the 1.5SMC130AHE3_A/I differ from bidirectional TVS diodes like 1.5SMC130CA?
The 1.5SMC130AHE3_A/I is unidirectional and features a cathode band for polarity-sensitive placement, whereas 1.5SMC130CA is bidirectional with no polarity marking and symmetrical clamping in both directions. The 1.5SMC130AHE3_A/I offers lower leakage (<1.0 μA) and is intended for DC-coupled lines like automotive power rails; the CA variant suits AC signal lines or floating buses where polarity reversal may occur.
