Product details
Overview
1.5SMC160CAHE3/9AT 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 delivers 1500 W peak pulse power (10/1000 μs), clamps at 219 V max under 6.8 A peak pulse current, and features a 136 V standoff voltage (VWM) with ±5% tolerance. Used in automotive sensor interfaces and industrial I/O protection where AEC-Q101 qualification and robust ESD/lightning immunity are required.
For engineers reviewing the 1.5SMC160CAHE3/9AT datasheet, 1.5SMC160CAHE3/9AT pinout, 1.5SMC160CAHE3/9AT application, or 1.5SMC160CAHE3/9AT equivalent, this page provides verified electrical specs, SMC (DO-214AB) package details, bidirectional clamping behavior, AEC-Q101 qualification status, and real-world design context for transient suppression in 12–48 V systems.
Technical Context
The 1.5SMC160CAHE3/9AT operates as a bidirectional avalanche diode, symmetrically clamping voltage transients above ±136 V in both polarities. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for protecting downstream MOSFETs and microcontrollers from inductive switching spikes.
Thermally rated for TJ = –65 °C to +150 °C, it uses a DO-214AB (SMC) package with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. The HE3 suffix confirms RoHS compliance and AEC-Q101 qualification-validated per stress test conditions including temperature cycling, HTRB, and UHAST.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff) | 136 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below system rail (e.g., 120 V DC bus). |
| VC @ IPPM | 219 V - Clamped voltage at 6.8 A peak pulse current (10/1000 μs); determines worst-case overvoltage seen by protected ICs. |
| PPPM | 1500 W - Peak pulse power handling capability; supports high-energy surges like ISO 7637-2 Pulse 5a (load dump) in automotive. |
| IPPM | 6.8 A - Peak pulse current at VC; used with PCB trace impedance to calculate actual clamping performance under layout constraints. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments without derating. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 8.0 mm × 8.0 mm copper pad requirement; compatible with automated reflow assembly. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including HTGB, TC, and AC/DC life testing; suitable for safety-critical ECUs. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional device with no polarity marking. Terminals are symmetrical anode/cathode - either end functions identically in circuit.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional terminal | Both terminals serve identical roles; no cathode band marking; enables placement without orientation check during SMT. |
Key Features

IC Role / Device Role / Timing Role: Primary TVS on channel-level input, positioned upstream of optocoupler or Schmitt trigger input stage. Use Value: Limits transient voltage to ≤219 V, preventing latch-up or gate oxide damage in input buffer ICs rated for 250 V absolute maximum. |
| Telecom Power Supply Input | Motor Drive Control Signal Line |
|
Use Scenario: Secondary-side surge suppression on 48 V telecom rectifier outputs exposed to lightning-induced common-mode surges on outdoor lines. IC Role / Device Role / Timing Role: Bidirectional shunt protector across output rails, clamping differential and common-mode transients simultaneously.

Use Scenario: Protecting isolated gate driver enable/disable signals in BLDC motor inverters from cross-talk and inverter switching noise. IC Role / Device Role / Timing Role: Low-capacitance (≈100 pF) TVS placed at driver input pin to suppress sub-10 ns ringing without distorting PWM edges. Use Value: Prevents false triggering of half-bridge drivers during high dV/dt commutation, eliminating shoot-through risk in 10–50 kHz motor control. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA-E3/52T | Lower PPPM (600 W), same VWM/VC, SMB package (smaller footprint, higher thermal resistance) | Not AEC-Q101 qualified; limited to commercial-grade consumer/industrial use | Select when board space is constrained and automotive qualification is not required. |
| 1.5KE160CA | Through-hole TO-218 package, identical electrical specs but higher mounting inductance and manual assembly requirement | Used in legacy industrial power supplies where reworkability and high-surge redundancy are prioritized over density | Choose for prototyping, repair, or high-reliability linear power supply designs where SMT is impractical. |
Compared with SMBJ160CA-E3/52T and 1.5KE160CA, the 1.5SMC160CAHE3/9AT uniquely combines AEC-Q101 qualification, 1500 W surge rating, and SMC package manufacturability-making it the only option qualified for production automotive electronics requiring zero-layout change upgrades from legacy through-hole TVS devices.

FAQ
What is the clamping voltage of the 1.5SMC160CAHE3/9AT at its rated peak pulse current?
The 1.5SMC160CAHE3/9AT clamps at a maximum of 219 V when subjected to its specified peak pulse current of 6.8 A (10/1000 μs waveform). This value is measured under standardized test conditions with 0.31" × 0.31" copper pads per terminal and represents the upper limit of voltage imposed on protected circuitry during a surge event. The 1.5SMC160CAHE3/9AT maintains this clamping performance across its full operating temperature range (–65 °C to +150 °C).
Is the 1.5SMC160CAHE3/9AT suitable for automotive applications?
Yes-the 1.5SMC160CAHE3/9AT carries the HE3 suffix, confirming it is RoHS-compliant and AEC-Q101 qualified. It has undergone rigorous stress testing including temperature cycling, high-temperature reverse bias, and unbiased highly accelerated stress testing (UHAST) per automotive reliability standards. The 1.5SMC160CAHE3/9AT is approved for use in engine control units, body control modules, and ADAS sensor interfaces where transient immunity and long-term stability are critical.
What does the "CA" suffix indicate in 1.5SMC160CAHE3/9AT?
The "CA" suffix denotes that the 1.5SMC160CAHE3/9AT is a bidirectional Transient Voltage Suppressor. Unlike unidirectional variants (e.g., "A" suffix), the CA version provides symmetrical clamping in both forward and reverse directions-ideal for AC-coupled signal lines, differential buses (e.g., CAN, RS-485), and floating power rails. The 1.5SMC160CAHE3/9AT has no polarity marking and can be mounted in either orientation on the PCB.
What is the standoff voltage (VWM) of the 1.5SMC160CAHE3/9AT, and how is it used in circuit design?
The standoff voltage (VWM) of the 1.5SMC160CAHE3/9AT is 136 V, representing the maximum continuous DC or RMS voltage the device can withstand without entering conduction. In design, VWM must exceed the normal operating voltage of the protected line-e.g., for a 120 V DC bus, 136 V provides a 13% safety margin. Exceeding VWM risks leakage current increase and premature clamping; the 1.5SMC160CAHE3/9AT guarantees <1 μA leakage at this voltage.
Does the 1.5SMC160CAHE3/9AT require special PCB layout considerations?
Yes-the 1.5SMC160CAHE3/9AT requires minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal to achieve its rated 1500 W peak pulse power. Smaller pads reduce thermal dissipation and cause premature failure under surge conditions. Short, wide traces should connect the 1.5SMC160CAHE3/9AT directly between protected line and ground, avoiding vias or routing near noisy components to preserve clamping speed and effectiveness.
