Overview
SMCG100CAHE3/57T 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 100 V stand-off voltage (VWM), 1500 W peak pulse power (PPPM), clamping voltage of 162 V at 9.3 A IPPM, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMCG100CAHE3/57T datasheet, SMCG100CAHE3/57T pinout, SMCG100CAHE3/57T application, or SMCG100CAHE3/57T equivalent, this device serves as a high-energy, low-clamping bidirectional TVS for automotive sensor lines, industrial I/O ports, and telecom interface protection where fast response (<1 ns), low incremental surge resistance, and MSL Level 1 reflow compatibility are critical.
Technical Context
The SMCG100CAHE3/57T operates as a bidirectional avalanche diode with symmetrical breakdown characteristics - minimum VBR of 111 V and maximum VBR of 123 V at 1 mA test current. Its glass-passivated junction ensures stable leakage performance (ID ≤ 1.0 μA at VWM) and long-term reliability under repetitive surge stress.
Thermally, it delivers RθJA = 75 °C/W on standard 8.0 mm × 8.0 mm copper pads and supports continuous operation up to TJ = +150 °C. The device meets JESD201 Class 2 whisker resistance and UL 497B recognition (QVGQ2, E136766) for both unidirectional and bidirectional configurations.

|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) in engine compartments exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed directly at connector entry point to shunt transients before reaching signal conditioning circuitry. Use Value: Limits transient voltage to ≤162 V while maintaining <1.0 µA leakage at 100 V nominal supply - preserving sensor accuracy and MCU input thresholds. |
Use Scenario: Safeguarding PLC digital input channels connected to 24 V DC field devices subject to inductive switching spikes and ESD events. IC Role / Device Role / Timing Role: Primary front-end TVS on each channel, mounted adjacent to terminal block to intercept surges before optocoupler or level-shifter inputs. Use Value: Delivers 1500 W surge handling with 111–123 V symmetric breakdown - enabling reliable operation across wide ambient temperature ranges (-55 °C to +150 °C). |
| Telecom Interface Protection | Power Supply Input Protection |
Use Scenario: Shielding RS-485/RS-422 transceivers in base station backhaul equipment from induced lightning surges and ground potential differences. IC Role / Device Role / Timing Role: Differential-mode TVS across A/B lines, leveraging bidirectional symmetry to suppress both positive and negative transients equally. Use Value: Achieves <1 ns response time and low clamping voltage - preventing latch-up or permanent damage to ±10 V tolerant transceivers. |
Use Scenario: Secondary overvoltage protection on 100 V intermediate bus rails feeding DC-DC converters in industrial power supplies. IC Role / Device Role / Timing Role: Standoff-clamp device placed after primary fuse and upstream of bulk capacitor to absorb residual surges escaping upstream filtering. Use Value: Maintains 100 V VWM margin while clamping to 162 V - ensuring downstream converter ICs (e.g., SiC gate drivers) remain within absolute maximum ratings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100A-E3/57T | Unidirectional, lower PPPM (400 W), SMA (DO-214AC) package, VWM = 100 V, VC = 165 V @ 2.5 A | Limited to DC-biased circuits; insufficient for AC or differential signal protection requiring bidirectional symmetry | Select only when polarity is fixed and surge energy is ≤400 W - not suitable as drop-in replacement for SMCG100CAHE3/57T in automotive or telecom interfaces. |
| SMCJ100CA | Bidirectional, same VWM/VC specs, but SMC (DO-214AB) package - larger footprint, higher RθJA (85 °C/W), non-AEC-Q101 rated | Acceptable for industrial use but lacks automotive qualification and has reduced thermal performance on standard PCBs | Choose only if AEC-Q101 is not required and board space allows larger SMC outline - requires thermal derating above 75 °C ambient. |
Compared with SMAJ100A-E3/57T and SMCJ100CA, SMCG100CAHE3/57T uniquely combines AEC-Q101 qualification, DO-215AB compactness, 1500 W surge capacity, and true bidirectional symmetry - making it the only option qualified for under-hood automotive sensor protection without layout or qualification compromise.

FAQ
What is the clamping voltage of SMCG100CAHE3/57T under a 10/1000 µs surge?
The SMCG100CAHE3/57T clamps to 162 V at 9.3 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and confirmed in the Vishay datasheet revision 09-Jan-2024. The clamping behavior remains symmetrical in both directions due to its bidirectional construction, ensuring consistent protection for AC-coupled or differential signal paths.
Is SMCG100CAHE3/57T suitable for automotive applications?
Yes, SMCG100CAHE3/57T is AEC-Q101 qualified and explicitly listed in Vishay's automotive-grade product documentation. It meets stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT). Its DO-215AB package supports MSL Level 1 reflow, and its -55 °C to +150 °C operating range aligns with under-hood automotive requirements - making SMCG100CAHE3/57T appropriate for engine control, ADAS sensor, and body electronics protection.
Does SMCG100CAHE3/57T have polarity markings?
No, SMCG100CAHE3/57T does not have polarity markings because it is a bidirectional TVS diode. The device features symmetrical breakdown characteristics in both directions, so either terminal may be connected to the protected line or ground without affecting performance. This eliminates orientation constraints during automated placement and simplifies PCB layout for differential or AC signal protection.
What is the maximum leakage current of SMCG100CAHE3/57T at its stand-off voltage?
The maximum reverse leakage current (ID) of SMCG100CAHE3/57T is 1.0 µA at its 100 V stand-off voltage (VWM), measured at TA = 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor interfaces and minimizes power loss in always-on automotive modules - a key advantage over higher-leakage alternatives like older P6KE-series devices.
What package type does SMCG100CAHE3/57T use, and what are its mounting requirements?
SMCG100CAHE3/57T uses the SMCG (DO-215AB) surface-mount package - a low-profile gull-wing variant with 0.050" lead pitch and UL 94 V-0 molding compound. Per Vishay's recommended layout, it must be mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal to achieve rated thermal and surge performance. The device is compatible with J-STD-002 and JESD22-B102 soldering standards and supports peak reflow temperatures up to 260 °C.
