Product details
Overview
1.5SMC160CAHE3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 160 V standoff voltage (VWM), 185 V minimum breakdown voltage (VBR), 219 V maximum clamping voltage (VC) at 6.8 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5SMC160CAHE3/57T datasheet, 1.5SMC160CAHE3/57T pinout, 1.5SMC160CAHE3/57T application, or 1.5SMC160CAHE3/57T equivalent, key selection criteria include bidirectional clamping performance, AEC-Q101 qualification, SMC (DO-214AB) package thermal resistance, and compliance with UL 497B for telecom and automotive transient immunity.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM), then rapidly switches to low-impedance conduction when transient voltage exceeds VBR, diverting surge current away from downstream circuitry. Its glass-passivated junction ensures stable avalanche characteristics and low leakage (<1 μA at VWM).
Designed for repetitive transients up to 0.01% duty cycle, it sustains 1500 W peak pulse power with minimal derating up to 125 °C ambient, supported by RθJA = 75 °C/W and RθJL = 15 °C/W thermal metrics. The bidirectional symmetry enables use on AC-coupled or floating lines without polarity concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 160 V - Maximum continuous reverse operating voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 185 V min - Voltage at which device enters avalanche conduction at 1 mA test current; ensures reliable triggering above system nominal voltage. |
| VC (Clamping) | 219 V max at IPPM = 6.8 A - Peak voltage seen across protected circuit during 10/1000 μs surge; determines stress on downstream components. |
| PPPM | 1500 W - Surge energy handling capability per IEEE C62.35 10/1000 μs waveform; supports lightning and inductive-switching immunity per IEC 61000-4-5. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments and industrial enclosures. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per AEC specification; required for engine control and ADAS modules. |

The 1.5SMC160CAHE3/57T has a maximum clamping voltage (VC) of 219 V at 6.8 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per JEDEC standards and guarantees that downstream circuitry experiences no more than 219 V during specified surge events - critical for protecting 200 V-rated capacitors and 3.3 V/5 V logic interfaces.
Is the 1.5SMC160CAHE3/57T suitable for automotive applications?
Yes, the 1.5SMC160CAHE3/57T is AEC-Q101 qualified and specifically designated for automotive use via the "HE3" suffix. It meets temperature cycling, high-temperature reverse bias (HTRB), and ESD requirements for engine control, body electronics, and ADAS sensor modules - validated across -65 °C to +150 °C junction temperature range.
How does the bidirectional design of the 1.5SMC160CAHE3/57T affect PCB layout?
The 1.5SMC160CAHE3/57T has no polarity marking and symmetrical bidirectional conduction, so PCB layout requires no orientation alignment. Both terminals are electrically equivalent - simplifying routing on differential lines like CAN, RS-485, or bridge sensor outputs, and eliminating risk of reverse installation in automated assembly.
What is the thermal resistance of the 1.5SMC160CAHE3/57T in standard mounting conditions?
When mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per Vishay's recommended layout, the 1.5SMC160CAHE3/57T exhibits RθJA = 75 °C/W and RθJL = 15 °C/W. These values enable sustained 6.5 W power dissipation at 50 °C ambient and support thermal design for high-duty-cycle surge environments such as industrial motor drives.
Does the 1.5SMC160CAHE3/57T meet UL safety certification requirements?
Yes, the 1.5SMC160CAHE3/57T is Underwriters Laboratories recognized under UL 497B (QVGQ2) for protector classification, with file number E136766.
