Product details
Overview
SMCG36C-E3/9AT from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) in DO-215AB (SMCG) package, rated for 36 V stand-off voltage, 1500 W peak pulse power, and clamping voltage of 58.1 V at 25.8 A. It protects sensitive signal lines and power rails in automotive and industrial electronics against ESD and inductive switching transients.
For engineers reviewing the SMCG36C-E3/9AT datasheet, SMCG36C-E3/9AT pinout, SMCG36C-E3/9AT application, or SMCG36C-E3/9AT equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, 1500 W surge rating with 10/1000 µs waveform, low thermal resistance (RθJA = 75 °C/W), and RoHS-compliant matte tin terminations.
Technical Context
This bi-directional TVS diode operates symmetrically across both polarities, with breakdown voltage VBR min/max = 40.0 V / 44.2 V at 1.0 mA test current and maximum reverse leakage ID = 1.0 µA at VWM = 36 V. Its clamping behavior is specified under standardized 10/1000 µs surge conditions.
Designed for surface-mount automated assembly, it features glass-passivated junction, meets MSL Level 1 per J-STD-020 (260 °C peak reflow), and is qualified to AEC-Q101 for automotive-grade reliability. Junction temperature range is −55 °C to +150 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36CA | DO-214AC (SMA) package; lower PPPM = 400 W; VC = 58.1 V at 6.8 A | Lower surge capacity limits use to consumer-grade or low-energy industrial signals | Select when board space is constrained and surge threat level is ≤400 W |
| SMCJ36CA | DO-214AB (SMC) package; same PPPM = 1500 W; VC = 58.1 V at 25.8 A; RθJA = 15 °C/W (lower) | Better thermal performance but larger footprint; suited for high-power PCBs with heatsinking | Select when thermal management is critical and DO-215AB footprint is not required |
Compared with SMAJ36CA and SMCJ36CA, SMCG36C-E3/9AT delivers identical clamping voltage and surge rating in a smaller DO-215AB footprint, enabling higher-density layouts while maintaining AEC-Q101 compliance - ideal for space-constrained automotive modules.

FAQ
What does the "C" suffix in SMCG36C-E3/9AT indicate?
The "C" in SMCG36C-E3/9AT denotes bi-directional configuration, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. This distinguishes it from uni-directional variants (e.g., SMCG36A), which require correct polarity orientation. The SMCG36C-E3/9AT has no cathode marking and functions identically regardless of terminal connection order.
Is SMCG36C-E3/9AT suitable for automotive applications?
Yes, SMCG36C-E3/9AT is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its −55 °C to +150 °C operating junction temperature range, MSL Level 1 reflow compatibility, and glass-passivated junction meet stringent automotive reliability requirements - confirmed in Vishay document 88457.
What is the clamping voltage of SMCG36C-E3/9AT under surge conditions?
The SMCG36C-E3/9AT clamps to a maximum of 58.1 V when subjected to its rated 10/1000 µs surge current of 25.8 A. This value is measured per ANSI/IEEE C62.35 standards and ensures downstream components with 40 V–60 V absolute maximum ratings remain within safe operating limits during transient events.
How does the DO-215AB package of SMCG36C-E3/9AT compare to DO-214AB (SMC)?
The DO-215AB (SMCG) package of SMCG36C-E3/9AT is smaller than DO-214AB (SMC), offering reduced PCB area while maintaining 1500 W surge capability. Its gull-wing leads enable finer pitch placement and improved manufacturability in automated SMT lines, whereas DO-214AB uses J-leads and occupies ~30% more board space - verified in Vishay mechanical drawings.
Does SMCG36C-E3/9AT require derating at elevated ambient temperatures?
Yes, SMCG36C-E3/9AT must be derated above TA = 25 °C per Figure 2 in Vishay document 88457. At 85 °C ambient, its peak pulse power drops to ~75% of 1500 W (≈1125 W), and at 125 °C, it falls to ~40% (≈600 W). Derating ensures junction temperature stays within the 150 °C limit and preserves long-term reliability of the SMCG36C-E3/9AT.
