Product details
Overview
SMCG160AHE3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for high-energy surge protection with 160 V stand-off voltage (VWM), 178–197 V breakdown voltage (VBR), and 1500 W peak pulse power (PPPM) at 10/1000 µs. It features AEC-Q101 qualification, low incremental surge resistance, and clamps to 259 V at rated IPPM - used to protect automotive power rails and industrial sensor interfaces against inductive switching transients.
For engineers reviewing the SMCG160AHE3/57T datasheet, SMCG160AHE3/57T pinout, SMCG160AHE3/57T application, or SMCG160AHE3/57T equivalent, key selection criteria include VWM/VBR matching, clamping voltage under 10/1000 µs surge, AEC-Q101 compliance for automotive use, thermal resistance (RθJA = 75 °C/W), and DO-215AB footprint compatibility with automated SMT assembly.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging a glass-passivated silicon junction to achieve sub-nanosecond response time and stable breakdown characteristics across temperature. Its bidirectional counterpart (e.g., SMCG160CA) shares identical VBR and PPPM but lacks polarity marking and supports symmetrical surge suppression.
The SMCG160AHE3/57T is rated for TJ = –55 °C to +150 °C, with maximum reverse leakage ID ≤ 1.0 µA at VWM and clamping voltage VC = 259 V at IPPM - verified under standardized 10/1000 µs waveform per ANSI/IEEE C62.35. Thermal performance relies on 0.31" × 0.31" copper pads per terminal per JEDEC test condition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - maximum continuous reverse operating voltage before clamping begins; defines safe working margin for 12 V/24 V/48 V automotive and industrial DC rails. |
| VBR min/max | 178 V / 197 V at IT = 1.0 mA - ensures reliable turn-on within ±5.6% tolerance, critical for predictable overvoltage thresholding. |
| PPPM | 1500 W at 10/1000 µs - delivers robust protection against ISO 7637-2 Pulse 1/2a/5a surges without degradation. |
| VC @ IPPM | 259 V - clamping voltage during full-rated surge; limits downstream IC stress to <260 V under worst-case transient. |
| ID @ VWM | ≤ 1.0 µA - ultra-low leakage preserves signal integrity and battery life in always-on automotive modules. |
| RθJA | 75 °C/W - thermal resistance enables 6.5 W steady-state dissipation on standard PCB copper; requires no heatsink for intermittent surge duty. |
| AEC-Q101 | Qualified - validated for automotive underhood applications including engine control units, body controllers, and ADAS sensor power supplies. |

FAQ
What is the clamping voltage of the SMCG160AHE3/57T under full-rated surge conditions?
The SMCG160AHE3/57T clamps to 259 V when subjected to its maximum rated peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured at TA = 25 °C on the recommended 0.31" × 0.31" copper pad layout and represents the upper voltage limit imposed on protected circuitry during a 1500 W transient event. The SMCG160AHE3/57T maintains this clamping performance across its operational temperature range.
Is the SMCG160AHE3/57T suitable for automotive applications?
Yes, the SMCG160AHE3/57T is explicitly AEC-Q101 qualified and manufactured with HE3 suffix indicating RoHS compliance and automotive-grade screening. It meets requirements for underhood deployment including thermal cycling, humidity resistance, and mechanical shock - validated for use in engine control units, body electronics, and ADAS power domains. The SMCG160AHE3/57T datasheet confirms qualification per AEC-Q101 Rev H.
What does the "HE3/57T" suffix indicate in SMCG160AHE3/57T?
The "HE3" suffix denotes RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads meeting JESD201 Class 2 whisker resistance. The "57T" indicates packaging in 7-inch diameter plastic tape and reel, with 850 units per reel - optimized for high-speed pick-and-place assembly. This full designation distinguishes the SMCG160AHE3/57T from industrial-grade (E3) or halogen-free (HM3) variants.
How does the SMCG160AHE3/57T compare to bidirectional TVS diodes like SMCG160CA?
The SMCG160AHE3/57T is unidirectional and features a cathode band for polarity identification, while SMCG160CA is bidirectional with no marking and symmetrical VBR in both directions. Both share identical VWM (160 V), PPPM (1500 W), and DO-215AB packaging, but only the unidirectional SMCG160AHE3/57T supports forward conduction and is used where polarity is fixed - such as DC power rail protection. The SMCG160AHE3/57T cannot replace SMCG160CA in AC or differential line applications.
What is the maximum operating temperature for the SMCG160AHE3/57T?
The SMCG160AHE3/57T has a specified operating junction temperature range of –55 °C to +150 °C, with storage temperature matching this span. Its thermal resistance (RθJA = 75 °C/W) allows sustained 6.5 W power dissipation at TA = 50 °C when mounted on the recommended copper pad layout. Derating applies above 25 °C ambient, per Figure 2 in the Vishay document 88457 - ensuring the SMCG160AHE3/57T remains within safe thermal limits in automotive underhood environments.
