Product details
Overview
SMCG10CAHE3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for robust overvoltage protection on signal and power lines. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (10/1000 µs), clamping voltage of 17.0 V at 88.2 A IPPM, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMCG10CAHE3/57T datasheet, SMCG10CAHE3/57T pinout, SMCG10CAHE3/57T application, or SMCG10CAHE3/57T equivalent, key selection criteria include bidirectional clamping behavior, low clamping ratio (VC/VWM ≈ 1.7), RoHS-compliant AEC-Q101 qualification, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This device operates as a voltage-clamped surge protector using an avalanche junction structure, responding to transients within picoseconds. Its bidirectional symmetry ensures identical clamping in both polarities, eliminating polarity dependency in AC-coupled or differential signal paths.
The SMCG10CAHE3/57T is rated for -55 °C to +150 °C operating junction temperature, with thermal resistance RθJA = 75 °C/W and RθJL = 15 °C/W, enabling reliable operation under high ambient conditions when mounted per recommended pad layout.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA | Same VWM (10 V) and bidirectional configuration, but lower PPPM (400 W) and larger SMA (DO-214AC) package | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 | Select SMAJ10CA only for cost-sensitive consumer designs with verified sub-400 W surge exposure |
| 1.5KE10CA | Higher PPPM (1500 W) but axial-leaded DO-201AD package; not SMT-compatible | Requires through-hole assembly and board real estate; incompatible with automated SMT lines | Choose 1.5KE10CA only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with SMAJ10CA and 1.5KE10CA, the SMCG10CAHE3/57T delivers identical 10 V bidirectional clamping with full 1500 W surge capability in a compact, AEC-Q101-qualified SMT package-enabling automotive-grade reliability without layout or process compromise.

FAQ
What is the clamping voltage of the SMCG10CAHE3/57T and how is it measured?
The SMCG10CAHE3/57T has a maximum clamping voltage (VC) of 17.0 V at a peak pulse current (IPPM) of 88.2 A, tested with a 10/1000 µs waveform per IEC 61000-4-5. This value is measured across the device terminals under standardized surge conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The SMCG10CAHE3/57T maintains this clamping performance across its full operating temperature range.
Is the SMCG10CAHE3/57T suitable for automotive applications?
Yes, the SMCG10CAHE3/57T is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass-passivated junctions, MSL Level 1 moisture sensitivity, and operation from -55 °C to +150 °C junction temperature-meeting requirements for engine control units, body electronics, and ADAS sensor interfaces. The SMCG10CAHE3/57T is listed in Vishay's automotive-grade product portfolio with full qualification documentation.
Does the SMCG10CAHE3/57T have polarity markings, and how is it connected in circuit?
No, the SMCG10CAHE3/57T has no polarity marking because it is a bidirectional TVS diode. Both terminals are functionally identical: one serves as anode during positive transients and cathode during negative transients. In PCB layout, it is placed symmetrically across the protected line and ground (or differential pair), with no orientation requirement. This simplifies placement and eliminates risk of reverse installation compared to unidirectional variants like SMCG10A.
What is the thermal resistance of the SMCG10CAHE3/57T and how does it affect PCB layout?
The SMCG10CAHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead (RθJL) of 15 °C/W, measured on the minimum recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pad per terminal. To achieve rated power dissipation, PCB layout must replicate this pad area and use internal ground planes for heat spreading. Reducing pad size increases thermal impedance and derates the 1500 W PPPM capability.
How does the SMCG10CAHE3/57T compare to unidirectional TVS diodes like SMCG10A in terms of electrical behavior?
The SMCG10CAHE3/57T provides symmetrical clamping in both directions with identical VBR (11.1–12.3 V), VC (17.0 V), and IPPM (88.2 A), whereas SMCG10A conducts only in reverse bias and blocks forward current. This makes the SMCG10CAHE3/57T ideal for AC-coupled, differential, or floating signal lines where polarity is undefined. Unlike SMCG10A, the SMCG10CAHE3/57T has no cathode band marking and requires no polarity-aware routing.
