Product details
Overview
SM15T200CA-E3/9AT from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in SMC (DO-214AB) package, rated for 1500 W peak pulse power (10/1000 μs), 200 V standoff voltage (VWM), 220 V minimum breakdown voltage (VBR), and clamps to 274 V at 5.5 A peak pulse current (IPPM). It protects I/O lines and power rails in automotive sensor units against lightning-induced and inductive-switching transients.
For engineers reviewing the SM15T200CA-E3/9AT datasheet, SM15T200CA-E3/9AT pinout, SM15T200CA-E3/9AT application, or SM15T200CA-E3/9AT equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification eligibility (via HE3 suffix), RoHS-compliant matte tin terminations, and thermal resistance (RθJA = 75 °C/W) under standard PCB pad layout.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical reverse/forward conduction behavior due to its bidirectional construction. Its silicon avalanche junction delivers precise breakdown at 220 V (min) with ≤10.8 × 10⁻⁴/°C temperature coefficient (αT), enabling stable clamping across -65 °C to +150 °C operating range.
Designed for high-energy transient suppression, it sustains 1500 W peak pulse power per 10/1000 μs waveform while limiting clamped voltage to 274 V at IPPM - critical for safeguarding 200 V-rated MOSFETs and microcontrollers in industrial motor drives and automotive body control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 200 V - maximum continuous reverse voltage before significant leakage; defines safe operating margin below system rail. |
| VBR (Breakdown Voltage) | 220 V min - guaranteed avalanche initiation threshold at 1 mA test current; ensures predictable clamping onset. |
| VC (Clamping Voltage) | 274 V at 5.5 A (10/1000 μs) - peak voltage seen by protected circuit during worst-case surge; determines stress on downstream ICs. |
| PPPM | 1500 W - energy-handling capacity for standardized lightning-surge waveforms; validates suitability for IEC 61000-4-5 Level 4. |
| RθJA | 75 °C/W - junction-to-ambient thermal resistance on 8.0 mm × 8.0 mm copper pads; informs derating above 25 °C ambient. |
| TJ max. | +150 °C - maximum junction temperature; enables operation in under-hood automotive environments. |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height; supports automated placement. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200CA | Lower PPPM (400 W), same VWM (200 V), higher VC (324 V at 1.2 A), SOD-123FL package (smaller, lower thermal mass) | Not suitable for IEC 61000-4-5 Level 4; limited to low-energy ESD/EFT in space-constrained consumer ports | Select SMAJ200CA only when board area is critical and surge threat level is ≤1 kV/500 A. |
| SMCJ200CA | Same PPPM (1500 W), identical VWM/VBR/VC specs, but larger SMC package with 10.3 mm × 8.6 mm footprint and RθJA = 50 °C/W | Superior thermal performance enables higher sustained surge duty cycles in high-temperature enclosures | Choose SMCJ200CA where ambient exceeds 85 °C or multiple surges occur within seconds. |

FAQ
What does the "CA" suffix indicate in SM15T200CA-E3/9AT?
The "CA" suffix denotes a bidirectional configuration - meaning SM15T200CA-E3/9AT conducts symmetrically in both forward and reverse directions, making it ideal for protecting AC-coupled signals or floating buses where polarity is undefined. Unlike unidirectional "A" variants, SM15T200CA-E3/9AT has no cathode marking and requires no orientation-specific placement on PCB.
Is SM15T200CA-E3/9AT qualified for automotive use?
SM15T200CA-E3/9AT itself is RoHS-compliant commercial-grade; however, the SM15T200CA-HE3 variant (same electrical specs, AEC-Q101 qualified) is available for automotive applications. The "HE3" suffix indicates full AEC-Q101 stress testing, including temperature cycling, humidity bias, and mechanical shock - required for under-hood and safety-related systems.
What is the clamping voltage of SM15T200CA-E3/9AT at its rated peak pulse current?
SM15T200CA-E3/9AT clamps to a maximum of 274 V when subjected to its specified peak pulse current of 5.5 A under the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88380 and defines the upper voltage limit imposed on protected circuitry during surge events.
Can SM15T200CA-E3/9AT replace older P6SMB200CA devices?
Yes - SM15T200CA-E3/9AT offers identical VWM (200 V), VBR (220 V min), and VC (274 V) ratings as P6SMB200CA but in a smaller SMC (DO-214AB) package versus SMA (DO-214AC). It maintains the same 1500 W PPPM rating and is backward-compatible in most layouts, though thermal design must account for higher RθJA (75 vs. ~60 °C/W).
What is the maximum operating temperature for SM15T200CA-E3/9AT?
SM15T200CA-E3/9AT has a maximum junction temperature (TJ max.) of +150 °C and an operating junction/storage temperature range of -65 °C to +150 °C. This allows reliable deployment in under-hood automotive environments and industrial enclosures where ambient temperatures exceed 105 °C, provided PCB copper pad area meets the 8.0 mm × 8.0 mm recommendation.
