Product details
Overview
SMC5K16AHM3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection on power and signal lines. It features 17.8–19.7 V breakdown voltage (VBR), 16 V stand-off voltage (VWM), 26.0 V clamping voltage (VC) at 192 A peak pulse current (IPPM), and 5000 W peak pulse power (10/1000 μs), used to protect MOSFETs and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the SMC5K16AHM3_A/I datasheet, SMC5K16AHM3_A/I pinout, SMC5K16AHM3_A/I application, or SMC5K16AHM3_A/I equivalent, this device delivers AEC-Q101 qualification, MSL Level 1 moisture sensitivity, UL 497B safety recognition, and robust 30 kV ESD immunity per IEC 61000-4-2 - critical for automotive-grade board-level surge resilience and long-term reliability validation.
Technical Context
This TVS diode operates as a unidirectional clamping device with fast response time (<1 ns) and low incremental surge resistance, enabling precise overvoltage limiting during transient events such as inductive load switching or lightning-induced surges. Its junction-to-mount thermal resistance of 4.0 °C/W supports stable operation under repetitive surge conditions in compact PCB layouts.
The SMC5K16AHM3_A/I is rated for -55 °C to +150 °C operating junction temperature and meets JESD 201 Class 2 whisker resistance requirements. Its halogen-free, RoHS-compliant construction and matte tin-plated terminals ensure compatibility with lead-free reflow processes per J-STD-002 and JESD 22-B102.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-M3/86A | Lower peak pulse power (400 W), SMA package (smaller footprint, lower thermal mass) | Suitable for low-energy consumer electronics; not AEC-Q101 qualified or UL recognized | Select when space-constrained and surge energy ≤400 W; avoid for automotive or industrial mains-connected designs |
| SMCJ16A-HM3 | Same SMC package, identical VWM/VBR, but rated for 1500 W (10/1000 μs) - not 5000 W | Lacks AEC-Q101 qualification and UL 497B recognition; intended for general industrial use only | Use where cost is prioritized over automotive compliance and high-energy surge margin; verify derating for repeated events |
Compared with SMC5K16AHM3_A/I, SMAJ16A-M3/86A offers smaller size but insufficient energy handling for automotive load dump, while SMCJ16A-HM3 matches form factor but lacks both AEC-Q101 and UL certification - making SMC5K16AHM3_A/I the only option meeting full automotive-grade surge, safety, and reliability requirements.

FAQ
What is the clamping voltage of SMC5K16AHM3_A/I at its rated peak pulse current?
The SMC5K16AHM3_A/I has a maximum clamping voltage (VC) of 26.0 V at 192 A peak pulse current (IPPM) under the 10/1000 μs waveform condition. This value is measured per Figure 3 in Vishay document 87742 and defines the upper voltage limit imposed on protected circuitry during a standardized surge event. The SMC5K16AHM3_A/I maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C).
Is SMC5K16AHM3_A/I qualified for automotive applications?
Yes, SMC5K16AHM3_A/I is AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 09-Jan-2024 (document 87742). This qualification applies specifically to the HM3 suffix variants of SMC5K10A through SMC5K20A, covering rigorous stress testing for temperature cycling, humidity, mechanical shock, and surge endurance. The SMC5K16AHM3_A/I is therefore approved for use in automotive powertrain, chassis, and body electronics.
What packaging format does SMC5K16AHM3_A/I ship in?
SMC5K16AHM3_A/I ships in 13-inch diameter plastic tape and reel packaging, with a base quantity of 3500 units per reel (ordering code suffix "/I"). The tape conforms to EIA-481 standards, and the device is mounted in standard SMC (DO-214AB) orientation with cathode band aligned per reel direction. This format supports high-speed automated placement in SMT lines without manual orientation handling.
Does SMC5K16AHM3_A/I meet UL safety standards?
Yes, SMC5K16AHM3_A/I carries UL recognition under file number E136766 for safety standard UL 497B, which covers surge protective components used in telecommunications and signaling circuits. This certification confirms compliance with flammability (UL 94 V-0), electrical spacing, and dielectric strength requirements - essential for inclusion in certified telecom and industrial equipment.
What is the maximum junction temperature rating for SMC5K16AHM3_A/I?
The SMC5K16AHM3_A/I has a maximum junction temperature (TJ) rating of +150 °C, as specified in the Absolute Maximum Ratings table of Vishay document 87742. This allows operation in under-hood automotive environments and high-temperature industrial enclosures. Derating curves in Figure 2 show that peak pulse power must be reduced linearly above 25 °C ambient to maintain TJ ≤ 150 °C during surge events.
