Product details
Overview
SMCG110AHE3/57T 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 110 V standoff voltage (VWM), 122–135 V breakdown voltage (VBR), and 1500 W peak pulse power (PPPM) at 10/1000 μs. It delivers 8.5 A peak pulse current (IPPM) and clamps transients to ≤177 V, targeting automotive power line and industrial sensor interface protection.
For engineers reviewing the SMCG110AHE3/57T datasheet, SMCG110AHE3/57T pinout, SMCG110AHE3/57T application, or SMCG110AHE3/57T equivalent, this AEC-Q101 qualified TVS offers verified bidirectional-capable packaging, low clamping ratio (VC/VBR ≈ 1.42), RoHS-compliant matte tin terminations, and MSL Level 1 reflow compatibility - critical for automotive ECU and industrial I/O module designs requiring robust EMC immunity.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, enabling sub-nanosecond response to ESD and lightning-induced transients. Its unidirectional polarity features a cathode band marking and supports forward surge current up to 200 A (8.3 ms half-sine), while thermal resistance (RθJA = 75 °C/W) assumes 8.0 mm × 8.0 mm copper pads per terminal.
The SMCG110AHE3/57T is rated for -55 °C to +150 °C junction temperature, meets UL 497B recognition (QVGQ2), and exhibits 1.0 μA max reverse leakage at VWM - optimized for low-power sensor signal lines and 12 V/24 V automotive subsystems where leakage-induced offset must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 110 V - maximum continuous reverse operating voltage before clamping begins; sets upper limit for protected circuit DC bias |
| VBR min/max | 122 V / 135 V at 1.0 mA test current - defines guaranteed avalanche onset window for design margining |
| VC @ IPPM | ≤177 V at 8.5 A - clamping voltage under 10/1000 μs surge; determines maximum stress on downstream ICs |
| PPPM | 1500 W - peak transient energy absorption capability; enables protection against ISO 7637-2 Pulse 5a/b surges |
| ID @ VWM | ≤1.0 μA - ultra-low reverse leakage ensures minimal loading on high-impedance sensor outputs |
| TJ max | +150 °C - extended junction rating supports under-hood automotive placement without derating |
| RθJA | 75 °C/W - thermal resistance measured on 8.0 mm × 8.0 mm copper pads; informs PCB thermal layout requirements |
Pinout & Package
Package: SMCG (DO-215AB) - surface-mount, low-profile gull-wing leaded case with matte tin-plated terminals, UL 94 V-0 molding compound, and AEC-Q101 qualification. Polarity marked by cathode band on unidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |

| Anode | Current entry point during forward conduction | Connected to ground or lower-potential rail in unidirectional clamp configuration |
| Cathode | Current exit point during forward conduction; marked with band | Connected to protected line (e.g., CAN_H, LIN, 12 V supply); conducts surge current to ground |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47 |
| Glass-passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift in harsh environments |
| MSL Level 1 (260 °C peak) | Enables standard SMT reflow without moisture sensitivity concerns or baking requirements |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 10605 ESD), improving clamping precision |
| UL 497B recognition (QVGQ2) | Confirms compliance for telecom and industrial signal line protection in safety-certified systems |
Applications

IC Role / Device Role / Timing Role: Primary-level TVS on 48 V input rail, coordinated with secondary-side protection to meet IEC 61000-4-5 Level 4. Use Value: 1500 W PPPM rating exceeds 10/1000 μs surge requirement for Class B telecom infrastructure; UL 497B recognition supports safety certification. |
Use Scenario: Input-stage surge suppression in AC/DC adapters for smart home devices subjected to mains-borne transients. IC Role / Device Role / Timing Role: Unidirectional clamp on primary-side DC bus (post-bridge rectifier) to prevent MOSFET or controller damage during line spikes. Use Value: AEC-Q101 qualification ensures long-term stability under thermal cycling; DO-215AB footprint supports automated placement in high-volume manufacturing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ110A-E3/57T | Same VWM (110 V) and PPPM (400 W), but lower 400 W rating and SMA (DO-214AC) package with higher RθJA (110 °C/W) | Limited to lower-energy transients (IEC 61000-4-5 Level 2); less suitable for automotive load dump | Select when cost or board space constraints outweigh need for 1500 W surge handling |
| SMCJ110AHE3/57T | Identical VWM (110 V), VBR (122–135 V), and PPPM (1500 W), but in larger SMC (DO-214AB) package with 50 °C/W RθJA | Better thermal performance for sustained surge duty cycles; requires more PCB area | Choose for high-reliability industrial systems where thermal headroom is prioritized over footprint |
Compared with SMAJ110A-E3/57T, SMCG110AHE3/57T delivers 3.75× higher surge power in a smaller DO-215AB footprint; versus SMCJ110AHE3/57T, it trades 25 °C/W higher thermal resistance for 30% smaller board area - ideal for space-constrained automotive modules.

FAQ
What is the clamping voltage of SMCG110AHE3/57T under a 10/1000 μs surge?
The SMCG110AHE3/57T clamps to a maximum of 177 V when subjected to its rated 8.5 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured per JEDEC standards and reflects worst-case voltage seen by downstream circuitry during surge events - critical for ensuring protected ICs remain within absolute maximum ratings.
Is SMCG110AHE3/57T suitable for bidirectional transient protection?
No - SMCG110AHE3/57T is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional operation, Vishay specifies the "CA" suffix (e.g., SMCG110CA). Using SMCG110AHE3/57T in bidirectional configurations risks failure during negative-going transients, as it lacks symmetrical avalanche characteristics.
Does SMCG110AHE3/57T require derating at elevated ambient temperatures?
Yes - the SMCG110AHE3/57T must be derated above TA = 25 °C per Figure 2 in the datasheet. At 85 °C ambient, its 1500 W PPPM rating drops to approximately 900 W due to thermal limitations. Designers must apply the published derating curve and verify junction temperature using RθJA = 75 °C/W and actual PCB copper area.
What is the meaning of the "HE3/57T" suffix in SMCG110AHE3/57T?
The "HE3" denotes RoHS-compliant construction with AEC-Q101 qualification and matte tin plating; "57T" specifies packaging in 7-inch plastic tape-and-reel format with 850 units per reel. This full suffix confirms the part meets automotive reliability standards and is optimized for high-speed SMT assembly without post-process baking.
How does the SMCG110AHE3/57T compare to SMAJ110A in terms of surge handling capability?
The SMCG110AHE3/57T provides 1500 W peak pulse power (PPPM), whereas SMAJ110A is rated for only 400 W. This 3.75× higher energy absorption enables SMCG110AHE3/57T to withstand automotive load dump and industrial lightning surges that would exceed SMAJ110A's capacity - making it the appropriate choice for demanding AEC-Q101 applications.
