Product details
Overview
SMCJ110AHE3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients up to 177 V at 8.5 A peak pulse current (10/1000 µs), with 110 V standoff voltage and 1500 W peak pulse power rating. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMCJ110AHE3/57T datasheet, SMCJ110AHE3/57T pinout, SMCJ110AHE3/57T application, or SMCJ110AHE3/57T equivalent, key selection criteria include unidirectional clamping behavior, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ110AHE3/57T uses a glass-passivated silicon junction optimized for fast response (<1 ps) to ESD and lightning-induced surges. Its breakdown voltage range is 122–135 V at 1 mA test current, with clamping voltage of 177 V at 8.5 A IPPM - enabling robust protection of 100–120 V DC bus interfaces without compromising system reliability.
Designed for unidirectional operation, it features a cathode band marking, 1.0 µA max reverse leakage at 110 V, and operates across -55 °C to +150 °C junction temperature. The device meets J-STD-020 MSL Level 1 and is qualified to AEC-Q101 for automotive under-hood applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110AHE3/52T | Lower PPPM (600 W), smaller SMB (DO-214AA) package, same VWM/VBR specs | Limited to lower-energy transients; unsuitable for load dump or high-current surge environments | Select when board space is constrained and surge energy remains below 600 W |
| SMCJ110CAHE3/57T | Bidirectional variant; identical VWM, VBR, and PPPM but symmetric clamping in both polarities | Required for AC-coupled or floating signal lines where polarity reversal may occur | Choose only if bidirectional protection is mandated by circuit topology or standard compliance |
Compared with SMBJ110AHE3/52T and SMCJ110CAHE3/57T, the SMCJ110AHE3/57T delivers higher surge robustness in unidirectional DC systems while maintaining AEC-Q101 qualification - making it optimal for automotive power modules and industrial DC bus protection where directional clamping suffices and energy levels exceed 600 W.

FAQ
What is the clamping voltage of SMCJ110AHE3/57T at its rated peak pulse current?
The SMCJ110AHE3/57T has a maximum clamping voltage (VC) of 177 V at 8.5 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured with the device mounted on 0.31″ × 0.31″ copper pads and defines the upper voltage limit imposed on protected circuitry during surge events. The SMCJ110AHE3/57T maintains this clamping performance across its full operating temperature range.
Is SMCJ110AHE3/57T qualified for automotive applications?
Yes, the SMCJ110AHE3/57T carries the HE3 suffix, indicating RoHS-compliance and full AEC-Q101 qualification. It has passed stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - confirming suitability for under-hood automotive use. The SMCJ110AHE3/57T is explicitly listed in Vishay's AEC-Q101 qualified product matrix for transient suppressors.
What does the "57T" suffix mean in SMCJ110AHE3/57T?
The "57T" suffix denotes the preferred packaging configuration: 7-inch diameter plastic tape and reel, with a base quantity of 850 units per reel. This format supports automated SMT placement and is compatible with standard pick-and-place equipment. The SMCJ110AHE3/57T uses matte tin-plated leads and meets J-STD-002 solderability requirements, ensuring reliable reflow soldering in high-volume manufacturing.
How does SMCJ110AHE3/57T differ from SMCJ110CAHE3/57T?
The SMCJ110AHE3/57T is unidirectional, with a cathode band marking and asymmetric conduction - conducting only in reverse bias during overvoltage events. The SMCJ110CAHE3/57T is bidirectional, offering symmetrical clamping in both polarities and no polarity marking. Both share identical VWM (110 V), VBR, PPPM (1500 W), and package, but the SMCJ110AHE3/57T is selected for DC circuits where polarity is fixed and surge direction is known.
What is the maximum operating temperature for SMCJ110AHE3/57T?
The SMCJ110AHE3/57T has a specified junction temperature range of -55 °C to +150 °C. Its thermal resistance RθJA is 75 °C/W under standard mounting conditions (0.31″ × 0.31″ copper pads), meaning that at 6.5 W steady-state dissipation, junction temperature rise above ambient is ~488 °C - which exceeds rating, confirming it is intended for transient-only operation. Continuous power dissipation must remain ≤6.5 W at TA = 50 °C, per datasheet limits.
