Product details
Overview
1.5SMC160CA-M3/9AT from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection on signal and power lines. It features 160 V standoff voltage (VWM), 179 V minimum breakdown voltage (VBR), 219 V maximum clamping voltage (VC) at 6.8 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5SMC160CA-M3/9AT datasheet, 1.5SMC160CA-M3/9AT pinout, 1.5SMC160CA-M3/9AT application, or 1.5SMC160CA-M3/9AT equivalent, key selection criteria include bidirectional clamping performance, M3 halogen-free RoHS compliance, SMC package thermal resistance (RθJL = 15 °C/W), and AEC-Q101 qualification eligibility via HM3 suffix variants.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering consistent clamping during positive and negative transients without polarity dependence. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ps), critical for protecting sensitive analog inputs and CAN/LIN bus nodes against ESD and lightning-induced surges.
The device sustains 1500 W peak pulse power under standardized 10/1000 μs waveform with 0.01% duty cycle, and derates linearly above 25 °C ambient per Fig. 2. Junction temperature range spans –65 °C to +150 °C, supporting operation in under-hood automotive environments and industrial control cabinets.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin for 12 V/24 V systems with transient headroom. |
| VBR (Breakdown Voltage) | 152–168 V at 1 mA - Tight 5% tolerance ensures predictable turn-on threshold across production lots and temperature. |
| VC (Clamping Voltage) | 219 V at IPPM = 6.8 A - Limits downstream voltage stress during surge events; enables robust protection of 200 V-rated MOSFETs or op-amps. |
| PPPM (Peak Pulse Power) | 1500 W - Handles high-energy transients like ISO 7637-2 Pulse 5a (load dump) without degradation when mounted on 8 mm × 8 mm copper pads. |
| ID (Reverse Leakage) | <1.0 μA at 136 V - Negligible standby current preserves battery life in always-on automotive modules and low-power IoT sensors. |
| TJ max. | +150 °C - Supports extended operation in engine control units, motor drives, and industrial PLCs with elevated ambient temperatures. |
| Package | SMC (DO-214AB) - Surface-mount footprint with 7.75 mm × 6.22 mm body and 2.62 mm height; compatible with automated pick-and-place and reflow profiles up to 260 °C (MSL Level 1). |
Pinout & Package
SMC (DO-214AB) package: molded epoxy case with matte tin-plated leads, UL 94 V-0 rated, no polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative half-cycle) | Conducts surge current during negative voltage excursions; symmetrical with cathode for bidirectional clamping. |
| Cathode | Transient current entry (positive half-cycle) | Conducts surge current during positive voltage excursions; electrically identical to anode in CA devices. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR, VC, and IPPM in both directions - eliminates need for polarity-aware layout in differential buses like RS-485 or CAN FD. |
| 1500 W peak pulse rating | Withstands ISO 16750-2 load dump and IEC 61000-4-5 surge events without failure when PCB layout meets 8 mm × 8 mm pad spec. |
| Halogen-free & RoHS-compliant (M3) | Meets JEDEC J-STD-020 MSL Level 1 and JESD 201 Class 2 whisker resistance - suitable for high-reliability automotive and medical assemblies. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage stress on protected ICs - critical for safeguarding 3.3 V/5 V microcontrollers and ADC front-ends in sensor nodes. |
| Fast response time (<1 ps) | Activates before transient energy couples into downstream circuitry - prevents latch-up or gate oxide damage in MOSFET drivers. |
Applications
| Automotive Sensor Protection | Industrial RS-485 Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA | Same VWM (136 V) and VC (219 V), but lower PPPM (600 W); SMB package (smaller footprint, higher RθJA = 100 °C/W). | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD only); unsuitable for ISO 7637-2 load dump. | Select when board space is constrained and surge energy is ≤600 W; verify thermal margin with smaller copper pads. |
| 1.5KE160CA | Same electrical specs but axial-leaded DO-15 package; higher RθJA (50 °C/W), not surface-mountable. | Requires through-hole assembly; incompatible with automated SMT lines and high-density layouts. | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with SMBJ160CA and 1.5KE160CA, the 1.5SMC160CA-M3/9AT delivers full 1500 W surge handling in an SMT-optimized SMC package with superior thermal coupling (RθJL = 15 °C/W), making it the preferred choice for automotive-grade and high-volume industrial production.

FAQ
What is the clamping voltage of the 1.5SMC160CA-M3/9AT at its rated peak pulse current?
The 1.5SMC160CA-M3/9AT has a maximum clamping voltage (VC) of 219 V at 6.8 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured with the device mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per JEDEC test conditions, ensuring realistic system-level protection margins for downstream components.
Is the 1.5SMC160CA-M3/9AT suitable for automotive applications?
Yes - the 1.5SMC160CA-M3/9AT is halogen-free and RoHS-compliant (M3 suffix), and belongs to the AEC-Q101-qualified 1.5SMC family. While the base M3 variant is commercial-grade, Vishay offers HM3-suffixed versions (e.g., 1.5SMC160CAHM3_B/I) that are fully AEC-Q101 qualified for under-hood and chassis-mounted automotive use.
How does the bidirectional design of the 1.5SMC160CA-M3/9AT affect PCB layout?
The 1.5SMC160CA-M3/9AT has no polarity marking and identical electrical behavior in both directions, eliminating orientation constraints during placement. This simplifies layout for differential signal lines (e.g., CAN, RS-485) and reduces risk of assembly error - unlike unidirectional TVS diodes that require strict cathode alignment.
What is the thermal resistance from junction to leads (RθJL) for the 1.5SMC160CA-M3/9AT?
The 1.5SMC160CA-M3/9AT has a typical junction-to-leads thermal resistance (RθJL) of 15 °C/W, enabling efficient heat transfer to PCB copper planes. This low value supports sustained operation under repetitive surge conditions and improves reliability in thermally demanding applications such as motor drive inverters and power supply inputs.
Does the 1.5SMC160CA-M3/9AT meet moisture sensitivity level (MSL) requirements for lead-free reflow?
Yes - the 1.5SMC160CA-M3/9AT meets MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. No dry-baking is required prior to assembly, supporting seamless integration into standard lead-free SMT processes used in automotive and industrial manufacturing.
