Product details
Overview
SMCJ110CAHE3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 1500 W peak pulse power rating, 110 V standoff voltage (VWM), and clamping voltage of 177 V at 8.5 A peak pulse current. It protects sensitive ICs, MOSFETs, and sensor signal lines against transients from inductive switching and lightning in automotive and industrial systems.
For engineers reviewing the SMCJ110CAHE3/57T datasheet, SMCJ110CAHE3/57T pinout, SMCJ110CAHE3/57T application, or SMCJ110CAHE3/57T equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 1500 W surge rating, 177 V max clamping voltage at IPPM, and RoHS-compliant matte tin-plated leads suitable for automated placement on PCBs.
Technical Context
The SMCJ110CAHE3/57T operates as a bidirectional avalanche diode with symmetrical breakdown characteristics-minimum VBR of 122 V and maximum of 135 V at 1 mA test current. Its low incremental surge resistance enables rapid clamping response to 10/1000 μs transients without degradation under repeated stress.
Thermally, it features RθJA = 75 °C/W and RθJL = 15 °C/W, supporting reliable operation up to TJ = +150 °C. The device meets MSL Level 1 per J-STD-020 with peak reflow temperature of 260 °C and is qualified to AEC-Q101 for automotive-grade reliability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CAHE3/52T | Lower PPPM (600 W), same VWM (110 V), SMB package (smaller footprint, higher RθJA = 110 °C/W). | Suitable for space-constrained consumer designs where surge threat level is ≤Level 3 (IEC 61000-4-5). | Select when board area is limited and thermal management allows lower power derating. |
| SMCJ110AHE3/57T | Unidirectional version; identical VWM/VC/PPPM but asymmetric conduction (cathode band marked; forward VF = 3.5 V @ 100 A). | Required where DC bias exists and reverse conduction must be blocked (e.g., 12 V supply rail with ground-referenced loads). | Choose only if circuit topology mandates unidirectional blocking; otherwise SMCJ110CAHE3/57T offers broader flexibility. |
Compared with SMBJ110CAHE3/52T, SMCJ110CAHE3/57T delivers 2.5× higher surge power handling and superior thermal performance; versus SMCJ110AHE3/57T, it provides symmetrical protection essential for AC-coupled or floating signal paths without polarity constraints.

FAQ
What is the clamping voltage of SMCJ110CAHE3/57T at its rated peak pulse current?
The SMCJ110CAHE3/57T has a maximum clamping voltage (VC) of 177 V at its specified peak pulse current (IPPM) of 8.5 A under a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's datasheet revision 09-Jan-2024. The clamping behavior is symmetrical in both directions due to its bidirectional construction, making SMCJ110CAHE3/57T suitable for protecting AC-coupled or floating nodes where polarity reversal may occur.
Is SMCJ110CAHE3/57T qualified for automotive use?
Yes, SMCJ110CAHE3/57T carries the HE3 suffix, indicating RoHS-compliance and full AEC-Q101 qualification per Vishay's ordering nomenclature. It undergoes stress testing for temperature cycling, humidity, mechanical shock, and surge endurance required for automotive grade 1 (−40 °C to +125 °C ambient) applications. This makes SMCJ110CAHE3/57T appropriate for under-hood ECUs, ADAS camera modules, and infotainment power supplies where field reliability is critical.
How does the SMCJ110CAHE3/57T differ from unidirectional SMCJ110AHE3/57T?
SMCJ110CAHE3/57T is bidirectional with symmetrical breakdown and no polarity marking, enabling protection of AC signals or floating buses. In contrast, SMCJ110AHE3/57T is unidirectional, features a cathode band, conducts forward current (VF = 3.5 V @ 100 A), and blocks reverse voltage only. Both share identical VWM (110 V), VC (177 V), and PPPM (1500 W), but SMCJ110CAHE3/57T is mandatory for applications like differential data lines or transformer-coupled interfaces where voltage polarity reverses.
What is the thermal resistance and mounting requirement for optimal performance of SMCJ110CAHE3/57T?
SMCJ110CAHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead (RθJL) of 15 °C/W, measured on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. To achieve rated 1500 W pulse power, PCB layout must follow Vishay's recommended pad dimensions and avoid thermal bottlenecks. Derating applies above TA = 25 °C per Figure 2 in the datasheet; at 70 °C ambient, maximum PPPM drops to ~1050 W.
Does SMCJ110CAHE3/57T meet moisture sensitivity and reflow standards for automated assembly?
Yes, SMCJ110CAHE3/57T meets MSL Level 1 per J-STD-020, allowing indefinite floor life and standard SMT reflow without pre-baking. Its peak reflow profile supports 260 °C maximum for ≤30 seconds, compatible with lead-free processes. Matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards, and whisker resistance meets JESD 201 Class 2-ensuring robust manufacturability in high-volume production of SMCJ110CAHE3/57T.
