Product details
Overview
SMCG110CAHE3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) surface-mount package, designed for high-energy surge protection on signal and power lines. It features a 110 V stand-off voltage (VWM), 122–135 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (10/1000 µs), clamping voltage of 177 V at 8.5 A IPPM, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMCG110CAHE3/57T datasheet, SMCG110CAHE3/57T pinout, SMCG110CAHE3/57T application, or SMCG110CAHE3/57T equivalent, this device is selected for robust ESD and lightning surge protection in automotive sensor interfaces, industrial I/O modules, and telecom line cards where bidirectional clamping, low leakage (<1 µA at VWM), and MSL Level 1 reflow compatibility are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR min/max (122–135 V), ID ≤ 1 µA at VWM = 110 V, and VC = 177 V at IPPM = 8.5 A under 10/1000 µs waveform. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
Thermal performance is defined by RθJA = 75 °C/W and RθJL = 15 °C/W, supporting operation from –55 °C to +150 °C junction temperature. The device meets UL 497B recognition (QVGQ2) and is rated for 200 A IFSM only in unidirectional configurations - not applicable here due to bidirectional construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 110 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 122 V / 135 V at IT = 1 mA - guaranteed breakdown range ensuring predictable turn-on threshold |
| VC @ IPPM | 177 V at 8.5 A - clamped voltage during 10/1000 µs surge, defining protected circuit voltage ceiling |
| PPPM | 1500 W - peak surge power handling capability per single transient event |
| ID @ VWM | ≤1 µA - ultra-low reverse leakage preserving signal integrity in high-impedance circuits |
| Package | SMCG (DO-215AB) - low-profile SMD outline with 0.31" × 0.31" copper pad requirement for thermal derating |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling and HTRB |
Pinout & Package
SMCG110CAHE3/57T uses the SMCG (DO-215AB) surface-mount package: a dual-leaded, gull-wing configuration with no polarity marking (bidirectional). Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional terminal pair | No functional distinction - either lead serves as anode or cathode depending on transient polarity |
| Lead 1 & Lead 2 | Surge current path | Both terminals conduct equally during positive or negative transients; no DC bias dependency |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating lines without polarity concerns |
| AEC-Q101 qualification | Validates suitability for automotive powertrain, body electronics, and ADAS sensor interfaces |
| MSL Level 1 rating | Supports standard reflow profiles up to 260 °C peak without preconditioning or dry-pack requirements |
| Glass-passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift |
| UL 497B recognition (QVGQ2) | Confirms compliance for telecom and industrial equipment safety certification |
Applications
| Automotive Sensor Interface Protection | Industrial Analog I/O Protection |
|---|---|
Use Scenario: Protecting LIN bus or analog sensor inputs (e.g., pressure, temperature) from load-dump and ISO 7637-2 pulses in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed between signal line and ground, responding within <1 ps to transients. Use Value: Limits induced surges to ≤177 V, preventing damage to downstream op-amps or ADC front-ends while maintaining <1 µA leakage at 110 V bias. |
Use Scenario: Safeguarding 4–20 mA current loop inputs in PLC analog input modules against field wiring surges and ESD. IC Role / Device Role / Timing Role: Transient shunt connected across loop terminals, conducting only during overvoltage events. Use Value: Absorbs 1500 W surges without degradation, enabling system-level IEC 61000-4-5 Level 4 compliance with minimal board space. |
| Telecom Line Card Surge Suppression | Consumer Device USB/DisplayPort ESD Protection |
Use Scenario: Front-end protection of Ethernet PHY or xDSL line drivers exposed to lightning-induced surges on outdoor-facing ports. IC Role / Device Role / Timing Role: Primary surge arrestor mounted at connector entry point, preceding secondary filtering. Use Value: Clamps 10/1000 µs surges to 177 V while sustaining 8.5 A peak current, preserving signal integrity up to 100 MHz. |
Use Scenario: Board-level ESD protection for high-speed differential pairs (e.g., USB 3.2 Gen 2, DP 1.4) in laptops and docking stations. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp placed adjacent to connector, minimizing stub length. Use Value: Delivers <1 µA leakage at 110 V and fast response to ±15 kV contact discharge (IEC 61000-4-2), with no DC blocking required. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ110CA | Same VWM (110 V) and PPPM (400 W), but lower power rating and SMA package (DO-214AC) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 or automotive load dump | Select SMAJ110CA only for cost-sensitive consumer applications with <400 W surge requirements. |
| SMCJ110CA | Identical VWM (110 V) and higher PPPM (1500 W), but larger SMC (DO-214AB) package and higher RθJA (50 °C/W) | Requires more PCB area and has reduced thermal margin under sustained surge duty cycles | Choose SMCJ110CA when legacy SMC footprint exists or when higher IFSM (200 A) is needed in unidirectional variants. |
Compared with SMCG110CAHE3/57T, SMAJ110CA offers lower cost but insufficient surge capacity for automotive or industrial use, while SMCJ110CA matches power rating but sacrifices board density and thermal efficiency due to larger footprint and inferior junction-to-ambient resistance.

FAQ
What is the clamping voltage of SMCG110CAHE3/57T and how is it measured?
The clamping voltage (VC) of SMCG110CAHE3/57T is 177 V, measured at a peak pulse current (IPPM) of 8.5 A under the standardized 10/1000 µs double-exponential surge waveform. This value defines the maximum voltage imposed on the protected circuit during a transient event and is verified per ANSI/IEEE C62.35 test conditions with the device mounted on 0.31" × 0.31" copper pads.
Is SMCG110CAHE3/57T suitable for automotive applications?
Yes, SMCG110CAHE3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its qualification covers temperature cycling, high-temperature reverse bias, and accelerated life testing per the AEC-Q101 stress test standard.
Does SMCG110CAHE3/57T have polarity markings on the package?
No, SMCG110CAHE3/57T is a bidirectional TVS diode and carries no polarity marking on the SMCG (DO-215AB) package. Both terminals are functionally identical, allowing installation without orientation concern - unlike unidirectional variants that feature a cathode band.
What is the maximum operating temperature for SMCG110CAHE3/57T?
The maximum operating junction temperature (TJ max.) for SMCG110CAHE3/57T is +150 °C, with a storage temperature range of –55 °C to +150 °C. Derating of peak pulse power begins above TA = 25 °C per Figure 2 in the datasheet, and thermal design must account for RθJA = 75 °C/W.
How does the HE3 suffix affect SMCG110CAHE3/57T specifications?
HE3 denotes RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads meeting JESD 201 Class 2 whisker resistance. It does not alter electrical parameters - all ratings (VWM, VBR, VC, PPPM) remain identical to non-HE3 variants; only material compliance and qualification status differ.
