Product details
Overview
SMCG130AHE3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for high-energy surge protection on power and signal lines. It features a 130 V stand-off voltage (VWM), 144–159 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (10/1000 µs), 7.2 A peak pulse current (IPPM), and clamps to 209 V at rated surge current. It is AEC-Q101 qualified and used in automotive power rail and sensor interface protection.
For engineers reviewing the SMCG130AHE3/57T datasheet, SMCG130AHE3/57T pinout, SMCG130AHE3/57T application, or SMCG130AHE3/57T equivalent, this page delivers verified electrical parameters, mechanical package details, real-world use cases, and validated alternative parts - all aligned with Vishay's official 88457 specification revision (09-Jan-2024).
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, activating when reverse voltage exceeds its breakdown threshold (VBR = 144–159 V). Its low incremental surge resistance and fast response time ensure effective suppression of transients induced by inductive load switching or ESD events.
Rated for 1500 W peak pulse power (10/1000 µs waveform), it sustains 200 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine) and operates across –55 °C to +150 °C junction temperature. The HE3 suffix confirms AEC-Q101 qualification, RoHS compliance, and matte tin-plated leads solderable per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working limit. |
| VBR (min/max) | 144 V / 159 V at IT = 1 mA - precise voltage range where avalanche conduction initiates; ensures predictable turn-on behavior. |
| VC @ IPPM | 209 V - clamping voltage under 7.2 A peak pulse current; determines maximum stress imposed on downstream components. |
| PPPM | 1500 W - peak transient energy absorption capability using standard 10/1000 µs waveform; critical for automotive load-dump immunity. |
| ID @ VWM | 1.0 µA - reverse leakage at rated stand-off voltage; low value minimizes standby power loss and avoids false triggering. |
| TJ max. | +150 °C - maximum junction temperature; supports under-hood automotive deployment without derating penalties. |
| RθJA | 75 °C/W - thermal resistance junction-to-ambient on 8.0 mm × 8.0 mm copper pads; informs PCB thermal design requirements. |
Pinout & Package
SMCG130AHE3/57T uses the SMCG (DO-215AB) surface-mount package: low-profile, gull-wing leads, UL 94 V-0 molding compound, and cathode band marking for polarity identification. Terminals are matte tin-plated and compliant with JESD 22-B102 whisker testing (Class 2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to ground or lower-potential node in unidirectional configuration. | Provides reference path for clamping action; must be routed with low-inductance connection to minimize overshoot during surge events. |
| Cathode | Current exit terminal in forward bias; marked with band; connected to protected line (e.g., 12 V rail or CAN bus). | Determines directionality - only conducts when cathode voltage exceeds anode by ≥VBR; defines protection orientation on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock - required for engine control, body electronics, and ADAS modules. |
| 1500 W peak pulse power | Withstands ISO 7637-2 Pulse 5a (load dump) surges up to 120 V for 400 ms without failure when properly heatsinked. |
| Low clamping ratio (VC/VBR ≈ 1.39) | Minimizes overvoltage exposure to protected ICs - e.g., keeps microcontroller I/O pins below absolute maximum ratings during transients. |
| MSL Level 1 (260 °C peak reflow) | Enables single-pass lead-free reflow assembly without moisture-induced damage; eliminates pre-bake requirement for production lines. |
| Glass passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift - critical for long-life industrial and automotive deployments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130A-E3/57T | Same VWM (130 V) and PPPM (400 W), but lower power rating; SMA (DO-214AC) package with higher RθJA (105 °C/W). | Limited to lower-energy transients (e.g., ESD-only); unsuitable for ISO 7637-2 load dump. | Select when cost or board space is prioritized over automotive-grade surge robustness. |
| SMCJ130A-E3/57T | Same VWM (130 V) and PPPM (1500 W), but SMC (DO-214AB) package; no AEC-Q101 qualification; RθJA = 60 °C/W. | Acceptable for industrial power supplies but not certified for automotive under-hood use. | Choose if AEC-Q101 is not mandated and thermal performance on smaller pads is acceptable. |
Compared with SMAJ130A-E3/57T and SMCJ130A-E3/57T, SMCG130AHE3/57T uniquely combines 1500 W surge capability, AEC-Q101 qualification, and DO-215AB low-profile packaging - making it the only option qualified for high-reliability automotive power rail protection without compromising clamping performance or thermal margin.

FAQ
What is the clamping voltage of SMCG130AHE3/57T under maximum rated surge current?
The SMCG130AHE3/57T clamps to 209 V when subjected to its rated peak pulse current (IPPM = 7.2 A) using the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's 88457 datasheet, Table 1. Clamping voltage directly determines the maximum overvoltage stress transferred to downstream components during transient events, making it a critical parameter for system-level surge immunity validation.
Is SMCG130AHE3/57T suitable for bidirectional transient protection?
No - SMCG130AHE3/57T is a unidirectional TVS diode, indicated by the "A" suffix (not "CA"). Its cathode band marking and asymmetric IV curve mean it only clamps in reverse bias. For bidirectional protection (e.g., AC lines or differential buses), Vishay specifies variants like SMCG130CA. Using SMCG130AHE3/57T in bidirectional applications risks forward conduction and failure during positive half-cycles.
What does the "HE3/57T" suffix signify in SMCG130AHE3/57T?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and matte tin-plated leads; "57T" indicates packaging in 7-inch plastic tape-and-reel format with 850 units per reel. This ordering code ensures traceability to Vishay's qualified automotive-grade production lot and guarantees compliance with J-STD-002 solderability and JESD 22-B102 whisker resistance Class 2 requirements.
How does the thermal resistance of SMCG130AHE3/57T affect PCB layout?
With RθJA = 75 °C/W (measured on 8.0 mm × 8.0 mm copper pads), SMCG130AHE3/57T requires minimum pad area and thermal vias to maintain TJ ≤ 150 °C under repeated surges. Reducing pad size increases junction temperature disproportionately - e.g., halving pad area may raise RθJA beyond 100 °C/W. Layout must follow Vishay's recommended mounting pad dimensions (0.31″ × 0.31″) to guarantee rated PPPM and lifetime reliability.
Can SMCG130AHE3/57T replace SMAJ130A in an existing design?
No direct replacement is advised. While both share VWM = 130 V, SMCG130AHE3/57T delivers 1500 W PPPM versus SMAJ130A's 400 W - meaning it handles 3.75× more surge energy. Substituting without redesign risks overstressing upstream fuses or PCB traces rated for lower energy. Additionally, SMCG130AHE3/57T's DO-215AB footprint differs from SMAJ130A's DO-214AC, requiring layout revision.
