Product details
Overview
SMCJ130CAHM3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 130 V standoff voltage (VWM), 1500 W peak pulse power (PPPM), and 209 V maximum clamping voltage (VC) at 7.2 A peak pulse current (IPPM). It protects sensitive ICs, MOSFETs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMCJ130CAHM3_A/H datasheet, SMCJ130CAHM3_A/H pinout, SMCJ130CAHM3_A/H application, or SMCJ130CAHM3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 1500 W surge rating, low thermal resistance (RθJL = 15 °C/W), and halogen-free RoHS-compliant construction.
Technical Context
This device operates as a voltage-clamped shunt protector, responding within picoseconds to transient overvoltages induced by inductive load switching or lightning surges. Its bidirectional symmetry ensures identical clamping behavior in both polarities, with breakdown voltage (VBR) specified at 144–159 V (min/max) under 1 mA test current.
Thermally optimized for surface-mount PCB layouts, it delivers 6.5 W steady-state power dissipation at TA = 50 °C and maintains stable operation across -55 °C to +150 °C junction temperature range. The glass-passivated junction and MSL Level 1 moisture sensitivity support robust reflow assembly without popcorn risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working margin for 12 V–48 V DC bus systems. |
| VBR min/max | 144 V / 159 V - Breakdown occurs within this range at 1 mA; ensures predictable turn-on threshold for transient suppression. |
| VC @ IPPM | 209 V - Clamped voltage at 7.2 A (10/1000 μs waveform); limits downstream stress on protected circuitry during surge events. |
| PPPM | 1500 W - Peak pulse power handling capacity; supports IEC 61000-4-5 Level 4 (4 kV/2 Ω) surge immunity testing. |
| RθJL | 15 °C/W - Junction-to-lead thermal resistance; enables efficient heat transfer to PCB copper pads without external heatsink. |
| TJ max | +150 °C - Maximum junction temperature; compatible with under-hood automotive environments and industrial enclosures. |
