Product details
Overview
1.5SMC160A-M3/9AT from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, rated for 1500 W peak pulse power (10/1000 μs), 136 V standoff voltage (VWM), and clamping to 219 V at 6.8 A peak pulse current - deployed for robust overvoltage protection of power rails and signal lines in automotive ECUs and industrial motor drives.
For engineers reviewing the 1.5SMC160A-M3/9AT datasheet, 1.5SMC160A-M3/9AT pinout, 1.5SMC160A-M3/9AT application, or 1.5SMC160A-M3/9AT equivalent, key selection criteria include verified clamping voltage under 10/1000 μs surge, unidirectional polarity with cathode band marking, halogen-free RoHS compliance (M3 suffix), and AEC-Q101 qualification readiness via HM3 variant.
Technical Context
This TVS diode operates as a fast-acting shunt protector: when reverse voltage exceeds 136 V (VWM), it avalanches at 152–168 V (VBR, 1 mA test current) and clamps transients to ≤219 V at 6.8 A (IPPM). Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 μA at VWM).
Thermally, it features RθJA = 75 °C/W and RθJL = 15 °C/W, enabling reliable operation up to TJ = 150 °C. It meets MSL Level 1 (260 °C peak reflow) and supports automated SMT placement on standard 8.0 mm × 8.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | Same VWM (136 V), but lower PPPM = 600 W and smaller SMB package (DO-214AA) | Limited to lower-energy surges; unsuitable for ISO 16750-2 load dump or IEC 61000-4-5 Level 4 | Select when board space is constrained and surge threat level is ≤600 W (e.g., secondary-side signal protection) |
| 1.5KE160A | Through-hole TO-204AE (DO-201AE) package; identical electrical specs but incompatible with SMT assembly | Requires wave soldering or hand-soldering; not viable for automated high-volume production | Choose only for legacy through-hole designs or prototyping where rework tolerance outweighs production efficiency |
Compared with SMBJ160A and 1.5KE160A, the 1.5SMC160A-M3/9AT delivers full 1500 W surge capability in an SMT-compatible, halogen-free, MSL Level 1 package - making it the optimal choice for new automotive and industrial designs requiring AEC-Q101 readiness and automated manufacturing.

FAQ
What is the clamping voltage of the 1.5SMC160A-M3/9AT under a 10/1000 μs surge?
The 1.5SMC160A-M3/9AT clamps to a maximum of 219 V when subjected to its rated peak pulse current of 6.8 A with a 10/1000 μs waveform. This value is measured per Figure 1 in Vishay's datasheet 88303 and reflects worst-case device behavior at TA = 25 °C on recommended 8.0 mm × 8.0 mm copper pads. The 1.5SMC160A-M3/9AT maintains this clamping performance across its operational temperature range.
Is the 1.5SMC160A-M3/9AT AEC-Q101 qualified?
The 1.5SMC160A-M3/9AT itself is not AEC-Q101 qualified; however, the HM3 variant (e.g., 1.5SMC160AHM3_A/I) carries full AEC-Q101 qualification for automotive applications. The M3 suffix denotes halogen-free, RoHS-compliant construction with MSL Level 1 rating - a prerequisite for automotive use but not equivalent to full qualification. For AEC-Q101 compliance, specify the HM3 ordering code.
What does the "-M3/9AT" suffix mean in 1.5SMC160A-M3/9AT?
The "M3" suffix indicates halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance, while "/9AT" specifies packaging in a 13-inch diameter plastic tape-and-reel format containing 3500 units. This configuration supports high-volume SMT placement and satisfies environmental and logistics requirements for industrial and automotive production lines using the 1.5SMC160A-M3/9AT.
How does the 1.5SMC160A-M3/9AT compare to bidirectional TVS diodes like 1.5SMC160CA?
The 1.5SMC160A-M3/9AT is unidirectional and protects only against positive-going transients relative to ground, with a cathode band marking polarity. In contrast, 1.5SMC160CA is bidirectional and symmetric - suitable for AC lines or differential signals. The 1.5SMC160A-M3/9AT offers identical VWM, VBR, and PPPM ratings but cannot replace 1.5SMC160CA in applications requiring dual-polarity clamping.
What is the thermal resistance of the 1.5SMC160A-M3/9AT, and how does it affect layout?
The 1.5SMC160A-M3/9AT has RθJA = 75 °C/W (junction-to-ambient) and RθJL = 15 °C/W (junction-to-leads), measured on 8.0 mm × 8.0 mm copper pads per terminal. To maintain safe junction temperatures, PCB layout must replicate this pad area - undersized traces or insufficient copper will raise operating temperature and reduce surge endurance. The 1.5SMC160A-M3/9AT relies on these thermal conditions to sustain its 150 °C TJ rating.
