Product details
Overview
1.5SMC160CA-M3/57T from Vishay General Semiconductor is a bidirectional 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 clamps to ≤219 V at 6.8 A peak pulse current. It protects sensitive signal lines and power rails in automotive sensor units and industrial control interfaces against lightning-induced transients and inductive switching surges.
For engineers reviewing the 1.5SMC160CA-M3/57T datasheet, 1.5SMC160CA-M3/57T pinout, 1.5SMC160CA-M3/57T application, or 1.5SMC160CA-M3/57T equivalent, this page delivers verified electrical parameters, thermal derating behavior, bidirectional clamping performance, RoHS-compliant halogen-free construction, and AEC-Q101 qualification status - all critical for ESD/surge protection design-in and BOM validation.
Technical Context
This bidirectional TVS operates symmetrically across both polarities with identical VBR (152–168 V), VWM (136 V), and VC (≤219 V) specifications. Its glass-passivated junction enables sub-nanosecond response time and low incremental surge resistance, ensuring effective clamping before downstream ICs experience overvoltage stress.
Designed for surface-mount automated assembly, it meets J-STD-020 MSL Level 1 (260 °C peak reflow) and JESD201 Class 2 whisker resistance. The SMC package provides 75 °C/W junction-to-ambient thermal resistance on standard 8.0 mm × 8.0 mm copper pads, supporting reliable operation up to TJ = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 136 V - Maximum continuous reverse voltage before leakage exceeds 1 µA; defines safe operating margin below clamping threshold |
| VBR (Breakdown) | 152–168 V at 1 mA - Verified breakdown range ensures predictable turn-on during transient events |
| VC (Clamping) | ≤219 V at IPPM = 6.8 A - Peak voltage seen by protected circuit under 10/1000 µs surge; determines maximum stress on downstream components |
| PPPM | 1500 W - Peak pulse power handling capability with 10/1000 µs waveform; defines transient energy absorption capacity |
| ID (Leakage) | ≤1 µA at VWM - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss |
| TJ max. | 150 °C - Maximum junction temperature rating; sets upper limit for thermal design and derating curves |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 0.320" body length and matte tin-plated leads for J-STD-002 solderability |
Pinout & Package
SMC (DO-214AB) package: low-profile, rectangular surface-mount case with two unmarked terminals; bidirectional symmetry means no polarity marking required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode / Cathode (bidirectional) | Either terminal serves as anode or cathode depending on transient polarity; symmetrical conduction enables dual-direction protection without orientation constraints |
| Terminal 2 | Anode / Cathode (bidirectional) | Electrically identical to Terminal 1; no functional distinction - device mounts in either orientation |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR, VWM, and VC in both directions eliminates need for polarity-aware layout or orientation checks |
| 1500 W peak pulse power | Handles high-energy transients (e.g., ISO 7637-2 Pulse 1/2a/5a) without degradation when mounted per recommended pad layout |
| Halogen-free & RoHS-compliant (M3 suffix) | Meets environmental compliance requirements for automotive and industrial end equipment without compromising surge robustness |
| AEC-Q101 qualified option | Available in HM3 variant for automotive applications requiring validated reliability under temperature cycling, HTRB, and mechanical shock |
| MSL Level 1 moisture sensitivity | Enables standard reflow assembly without dry-pack or baking; supports high-volume manufacturing throughput |

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 | Lower PPPM (600 W), same VWM (136 V), SMB package (smaller footprint, higher RθJA = 85 °C/W) | Preferred where board space is constrained but surge energy is limited to <600 W (e.g., low-power IoT sensors) | Select SMBJ160CA only if thermal budget allows higher junction temperature rise and peak surge energy remains ≤600 W. |
| 1.5KE160CA | Through-hole DO-201 package, identical VWM/VC/PPPM, but incompatible with SMT assembly and lacks MSL Level 1 rating | Suitable for legacy through-hole designs or prototyping where reflow compatibility is not required | Choose 1.5KE160CA only for manual assembly or repair scenarios; not recommended for new SMT production. |
Compared with SMBJ160CA and 1.5KE160CA, the 1.5SMC160CA-M3/57T uniquely combines 1500 W surge capability, SMT compatibility, MSL Level 1 reflow readiness, and halogen-free construction - making it the optimal choice for high-reliability automotive and industrial surface-mount systems requiring full AEC-Q101 alignment.

FAQ
What does the "CA" suffix mean in 1.5SMC160CA-M3/57T?
The "CA" suffix denotes a bidirectional configuration: the 1.5SMC160CA-M3/57T conducts identically in both polarities, with matched breakdown (152–168 V), standoff (136 V), and clamping (≤219 V) characteristics. This eliminates orientation concerns during placement and enables symmetric protection of differential or AC-coupled signal paths - a key advantage over unidirectional variants like 1.5SMC160A-M3/57T.
Is 1.5SMC160CA-M3/57T AEC-Q101 qualified?
The base 1.5SMC160CA-M3/57T is halogen-free and RoHS-compliant but not AEC-Q101 qualified. However, Vishay offers the HM3 variant (e.g., 1.5SMC160CAHM3_A/H) which carries full AEC-Q101 qualification including HTGB, TC, and HTRB testing - required for automotive powertrain and chassis applications. Always verify the full ordering code for qualification status.
What is the maximum clamping voltage of 1.5SMC160CA-M3/57T under surge conditions?
The 1.5SMC160CA-M3/57T clamps to a maximum of 219 V when subjected to its rated peak pulse current of 6.8 A (10/1000 µs waveform). This value is guaranteed across temperature and lifetime per Vishay's datasheet Figure 7, and represents the highest voltage the protected circuit will experience during a worst-case transient - critical for selecting downstream ICs with adequate voltage tolerance.
Can 1.5SMC160CA-M3/57T be used in place of a unidirectional TVS like 1.5SMC160A-M3/57T?
Yes, but only if bidirectional protection is required or acceptable. The 1.5SMC160CA-M3/57T provides identical VWM (136 V) and VC (≤219 V) as the unidirectional 1.5SMC160A-M3/57T, but conducts in both directions. Substituting it for a unidirectional part may cause unintended conduction in DC-biased circuits - always validate bias conditions and ensure no steady-state reverse current path exists.
What PCB pad layout is recommended for optimal thermal and surge performance of 1.5SMC160CA-M3/57T?
Vishay specifies mounting on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal to achieve rated 1500 W PPPM and 75 °C/W RθJA. Smaller pads reduce surge capability and increase junction temperature - e.g., halving pad area can degrade PPPM by ~30% and raise TJ by >20 °C under repeated surges. Use thermal vias under pads if ambient exceeds 70 °C.
