Product details
Overview
SMCG5.0AHE3/9AT from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor (TVS) in the SMCG (DO-215AB) package, with 5.0 V stand-off voltage (VWM), 6.40–7.07 V breakdown voltage (VBR) at 10 mA, 1500 W peak pulse power (PPPM), and 163 A peak pulse current (IPPM). It protects sensitive ICs and MOSFETs against inductive switching transients and ESD in automotive and industrial power rails.
For engineers reviewing the SMCG5.0AHE3/9AT datasheet, SMCG5.0AHE3/9AT pinout, SMCG5.0AHE3/9AT application, or SMCG5.0AHE3/9AT equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, clamping behavior under 10/1000 µs surge, thermal resistance (RθJA = 75 °C/W), and real-world protection use cases for 12 V automotive systems.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, designed to shunt transient energy above its breakdown threshold while maintaining low clamping voltage (VC = 9.20 V at IPPM). Its glass-passivated junction ensures stable leakage (<1000 µA at VWM) and fast response time (<1 ns).
Rated for TJ = –55 °C to +150 °C and qualified to AEC-Q101, it supports high-reliability automotive applications where surge immunity must be maintained across temperature extremes and board-level reflow profiles up to 260 °C (MSL Level 1).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse operating voltage before clamping begins; sets minimum system rail margin for 5 V logic or sensor interfaces. |
| VBR (min/max) | 6.40 V / 7.07 V at IT = 10 mA - Confirmed breakdown range ensures reliable turn-on without premature conduction during normal operation. |
| VC @ IPPM | 9.20 V at 163 A - Clamping voltage under 10/1000 µs surge defines maximum stress imposed on protected downstream circuitry. |
| PPPM | 1500 W - Peak transient power handling capability determines survivability against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 surges. |
| ID @ VWM | ≤1000 µA - Low reverse leakage preserves signal integrity and minimizes quiescent power loss in always-on circuits. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance informs heatsinking requirements when operating near PD = 6.5 W at elevated ambient temperatures. |
Pinout & Package
Package: SMCG (DO-215AB), surface-mount gull-wing lead frame with matte tin-plated terminals, compliant with J-STD-002 and JESD 22-B102 solderability standards. Polarity indicated by cathode band on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Same VWM (5.0 V) and VC (9.2 V), but lower PPPM (400 W) and smaller SMA (DO-214AC) package. | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a or high-current load dump. | Select SMAJ5.0A only for cost-sensitive consumer applications with sub-500 W surge requirements. |
| SMCJ5.0A | Identical VWM, VBR, and VC, but higher PPPM (1500 W) in larger SMC (DO-214AB) package with RθJA = 18 °C/W. | Better thermal performance in high-ambient environments; requires more PCB area than SMCG. | Choose SMCJ5.0A when board layout permits larger footprint and thermal management is critical above 85 °C ambient. |

FAQ
What is the clamping voltage of SMCG5.0AHE3/9AT under maximum surge conditions?
The SMCG5.0AHE3/9AT has a maximum clamping voltage (VC) of 9.20 V at its rated peak pulse current (IPPM) of 163 A, measured using the standardized 10/1000 µs double-exponential waveform. This value is guaranteed across the full operating temperature range and ensures downstream components see no more than 9.20 V during worst-case transients. The SMCG5.0AHE3/9AT maintains this clamping performance due to its low incremental surge resistance and glass-passivated junction.
Is SMCG5.0AHE3/9AT qualified for automotive applications?
Yes, SMCG5.0AHE3/9AT is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 09-Jan-2024 (Document Number: 88457). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD, making the SMCG5.0AHE3/9AT suitable for under-hood and chassis-mounted automotive modules. The HE3 suffix denotes AEC-Q101 qualification and RoHS compliance.
What does the "9AT" suffix indicate in SMCG5.0AHE3/9AT?
The "9AT" suffix in SMCG5.0AHE3/9AT specifies the packaging configuration: 13-inch diameter plastic tape and reel, with a base quantity of 3500 units per reel. This differs from the "57T" option (7-inch reel, 850 units). Both share identical electrical and thermal specifications; the suffix solely identifies mechanical packaging and logistics format for automated SMT placement.
How does SMCG5.0AHE3/9AT compare to bidirectional TVS diodes like SMCG5.0CA?
SMCG5.0AHE3/9AT is unidirectional, with polarity marked by a cathode band and forward conduction capability, whereas SMCG5.0CA is bidirectional and lacks polarity marking. The unidirectional version offers lower leakage (<1000 µA vs. doubled ID limit for low-VWM bidirectionals) and is preferred for DC power rail protection. SMCG5.0AHE3/9AT cannot replace SMCG5.0CA in AC-coupled or symmetrical signal line applications without circuit redesign.
What is the thermal resistance and maximum junction temperature of SMCG5.0AHE3/9AT?
The SMCG5.0AHE3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and a maximum junction temperature (TJ max.) of +150 °C. These values assume mounting on the recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. At TA = 50 °C, its power dissipation rating is 6.5 W. Exceeding TJ max. risks parametric shift or catastrophic failure, so thermal design must respect derating curves in Figure 2 of the Vishay datasheet for SMCG5.0AHE3/9AT.
