Product details
Overview
SMCG160CAHE3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 160 V stand-off voltage (VWM), 259 V maximum clamping voltage (VC) at 5.8 A peak pulse current (IPPM), and 1500 W peak pulse power dissipation (PPPM) with a 10/1000 µs waveform - deployed in automotive sensor signal lines, industrial I/O ports, and telecom interface protection.
For engineers reviewing the SMCG160CAHE3/57T datasheet, SMCG160CAHE3/57T pinout, SMCG160CAHE3/57T application, or SMCG160CAHE3/57T equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification for automotive use, low thermal resistance (RθJL = 15 °C/W), and compatibility with automated SMT placement on standard 8.0 mm × 8.0 mm copper pads.
Technical Context
This device operates as a voltage-clamped crowbar during transients, leveraging an avalanche breakdown mechanism to divert surge energy away from downstream circuitry. Its bidirectional architecture ensures symmetrical clamping in both polarities, with identical breakdown voltage range (178–197 V) and leakage current ≤1.0 µA at VWM.
Thermally, it sustains operation up to TJ = 150 °C and delivers 6.5 W power dissipation at TA = 50 °C, enabled by low junction-to-lead thermal resistance (15 °C/W) and UL 94 V-0 compliant molding compound - critical for reliability in high-temperature automotive engine bay or industrial control environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe signal swing margin for protected lines. |
| VBR (min/max) | 178 V / 197 V - Breakdown occurs within this band at 1 mA test current; ensures predictable turn-on across temperature and unit variation. |
| VC @ IPPM | 259 V at 5.8 A - Clamped voltage during 10/1000 µs surge; determines maximum stress imposed on downstream ICs or MOSFETs. |
| PPPM | 1500 W - Peak transient power it can absorb without failure; supports protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 surges. |
| ID @ VWM | ≤1.0 µA - Reverse leakage at rated stand-off voltage; minimizes standby power loss and avoids false triggering in high-impedance circuits. |
| TJ max. | +150 °C - Maximum junction temperature rating; enables deployment in under-hood automotive or enclosed industrial enclosures. |
| RθJL | 15 °C/W - Junction-to-lead thermal resistance; allows direct heat conduction into PCB copper, supporting high-reliability thermal design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-E3/57T | Unidirectional; same VWM (160 V), but lower PPPM (400 W); SMA (DO-214AC) package with higher RθJA (110 °C/W). | Limited to DC-biased lines; insufficient for bidirectional AC-coupled or floating interfaces like RS-485 or CAN. | Select only when polarity is fixed and surge energy is ≤400 W; verify layout thermal relief for SMA package. |
| SMCJ160CAHE3/57T | Bidirectional; higher PPPM (1500 W), identical VWM and VC, but larger SMC (DO-214AB) package (7.11 mm × 6.22 mm vs. SMCG's 7.11 mm × 5.59 mm). | Same functional role but requires larger PCB area; slightly higher parasitic inductance due to longer leads. | Prefer when existing SMC footprint is standardized; avoid if space-constrained or high-frequency transient response is critical. |

FAQ
What is the clamping voltage of SMCG160CAHE3/57T under a 10/1000 µs surge?
The SMCG160CAHE3/57T clamps to a maximum of 259 V when subjected to its rated peak pulse current of 5.8 A using the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and reflects worst-case voltage seen by protected circuitry during surge events - critical for ensuring downstream components remain within absolute maximum ratings.
Is SMCG160CAHE3/57T suitable for automotive applications?
Yes, SMCG160CAHE3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood and chassis-mounted modules. Its construction includes glass passivated junctions, MSL Level 1 reflow compatibility, and operation up to +150 °C junction temperature - meeting requirements for engine control units, ADAS sensors, and body electronics.
Does SMCG160CAHE3/57T have polarity markings on the package?
No, SMCG160CAHE3/57T does not feature polarity markings because it is a bidirectional TVS diode. Unlike unidirectional variants (e.g., SMCG160A), the CA suffix indicates symmetrical breakdown in both directions - eliminating the need for cathode band identification and simplifying PCB layout for AC-coupled or floating signal paths.
What is the thermal resistance from junction to ambient for SMCG160CAHE3/57T?
The typical junction-to-ambient thermal resistance (RθJA) of SMCG160CAHE3/57T is 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. However, its much lower junction-to-lead resistance (RθJL = 15 °C/W) emphasizes that effective heat transfer relies on robust solder joint conduction to PCB copper - not ambient convection alone.
How does SMCG160CAHE3/57T differ from SMCG160AHE3/57T?
SMCG160CAHE3/57T is bidirectional with symmetrical clamping in both polarities and no polarity marking, whereas SMCG160AHE3/57T is unidirectional with a cathode band and conducts only in reverse bias. The "CA" suffix denotes bidirectional capability - essential for protecting AC signals, differential buses, or floating nodes where voltage polarity reverses during normal operation or transients.
