Product details
Overview
SMCG9.0HE3/57T from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) in DO-215AB (SMCG) package, designed for clamping voltage transients on signal and power lines. It features 9.0 V stand-off voltage (VWM), 15.4 V maximum clamping voltage (VC) at 97.4 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 µs waveform. It is AEC-Q101 qualified and used to protect automotive sensor interfaces against inductive switching surges.
For engineers reviewing the SMCG9.0HE3/57T datasheet, SMCG9.0HE3/57T pinout, SMCG9.0HE3/57T application, or SMCG9.0HE3/57T equivalent, key selection criteria include bi-directional clamping capability, low incremental surge resistance, RoHS-compliant AEC-Q101 qualification, DO-215AB thermal performance (RθJA = 75 °C/W), and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCG9.0HE3/57T operates as a bi-directional avalanche diode, exhibiting symmetrical breakdown behavior in both polarities with VBR min/max of 10.0 V / 11.1 V at 1.0 mA test current. Its clamping response is defined by a 10/1000 µs double-exponential surge waveform per ANSI/IEEE C62.35, delivering consistent VC ≤ 15.4 V up to IPPM = 97.4 A.
Thermally, it supports junction temperatures from –55 °C to +150 °C, with RθJL = 15 °C/W enabling effective heat transfer to PCB leads. The device uses glass-passivated silicon junctions and matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102 solderability standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ9.0A-E3/52T | Uni-directional; VWM = 9.0 V, VC = 14.4 V @ 75.8 A, DO-214AC package | Requires polarity-aware layout; lower IPPM but tighter VC spec | Select when circuit ground reference is fixed and unidirectional clamping suffices |
| SMCJ9.0AHE3/57T | Uni-directional; same DO-215AB package; VWM = 9.0 V, VC = 14.4 V @ 104 A, higher PPPM = 1500 W | Not suitable for floating or AC-coupled lines due to cathode band marking | Choose only if design allows strict polarity orientation and needs marginally better surge current handling |
Compared with SMAJ9.0A-E3/52T and SMCJ9.0AHE3/57T, the SMCG9.0HE3/57T uniquely provides bi-directional clamping in the DO-215AB footprint without polarity constraints-critical for differential signaling, transformer-coupled interfaces, or space-constrained automotive modules where board real estate and layout flexibility are prioritized over marginal VC reduction.

FAQ
What is the clamping voltage of SMCG9.0HE3/57T under a 10/1000 µs surge?
The SMCG9.0HE3/57T has a maximum clamping voltage (VC) of 15.4 V when subjected to its rated peak pulse current of 97.4 A using the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet revision 14-Mar-12, ensuring predictable overvoltage limiting for protected ICs.
Is SMCG9.0HE3/57T suitable for automotive applications?
Yes, SMCG9.0HE3/57T is AEC-Q101 qualified and explicitly rated for automotive use. Its –55 °C to +150 °C operating junction temperature range, JESD 201 Class 2 whisker resistance, and DO-215AB package with MSL Level 1 reflow compatibility meet critical requirements for under-hood and body-control module deployments.
Does SMCG9.0HE3/57T have polarity markings?
No, SMCG9.0HE3/57T is a bi-directional TVS and carries no polarity marking. As stated in the Vishay datasheet, "no marking on bi-directional types." This enables symmetric placement across differential or floating signal lines without orientation constraints during automated assembly.
What is the thermal resistance of SMCG9.0HE3/57T?
The SMCG9.0HE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. Its junction-to-lead resistance (RθJL) is 15 °C/W, supporting efficient heat transfer to PCB traces in high-power surge events.
How does the HE3 suffix differ from E3 on SMCG9.0HE3/57T?
The HE3 suffix on SMCG9.0HE3/57T indicates RoHS compliance plus AEC-Q101 qualification and JESD 201 Class 2 whisker resistance-whereas E3 denotes RoHS compliance only (commercial grade). This distinction is critical for automotive designs requiring validated reliability beyond standard commercial specifications.
