Product details
Overview
1.5SMC16AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 1500 W peak pulse power (10/1000 μs), 13.6 V stand-off voltage (VWM), and 22.5 V clamping voltage (VC) at 66.7 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines against lightning-induced transients and inductive switching spikes in automotive and industrial power systems.
For engineers reviewing the 1.5SMC16AHM3/I datasheet, 1.5SMC16AHM3/I pinout, 1.5SMC16AHM3/I application, or 1.5SMC16AHM3/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), junction temperature range (–65 to +150 °C), and halogen-free RoHS-compliant construction per JESD201 Class 2 whisker test.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds 13.6 V (VWM), it transitions from high-impedance blocking to low-impedance conduction at breakdown (VBR = 15.2–16.8 V @ 1 mA), clamping transients to ≤22.5 V at 66.7 A. Its glass-passivated junction ensures stable avalanche behavior and fast response time (<1 ns).
Designed for automated SMT assembly, the 1.5SMC16AHM3/I meets MSL Level 1 (reflow peak 260 °C), features matte tin-plated leads compliant with J-STD-002 and JESD22-B102, and is qualified to AEC-Q101 for automotive under-hood applications. Polarity is marked by a cathode band on the SMC package body.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A-E3/52T | Lower PPPM (600 W), SMB package (smaller footprint), same VWM/VC specs. | Limited to lower-energy surges (IEC 61000-4-5 Level 2); unsuitable for automotive load dump. | Select when board space is constrained and surge threat level is moderate (e.g., consumer USB-C PD adapters). |
| 1.5KE16A | Through-hole DO-201 package, identical electrical specs but no AEC-Q101 or halogen-free certification. | Not qualified for automotive or high-reliability industrial use; requires wave soldering. | Choose only for legacy through-hole designs where SMT conversion is impractical and automotive compliance is not required. |
Compared with 1.5SMC16AHM3/I, SMBJ16A-E3/52T offers smaller size but sacrifices 60% peak power handling, while 1.5KE16A retains full electrical performance but lacks AEC-Q101 validation and modern environmental compliance-making 1.5SMC16AHM3/I the sole choice for new automotive and halogen-free industrial designs.

FAQ
What is the clamping voltage of the 1.5SMC16AHM3/I at its rated peak pulse current?
The 1.5SMC16AHM3/I clamps to a maximum of 22.5 V at its rated peak pulse current of 66.7 A under the standardized 10/1000 μs waveform. This value is measured per Figure 1 in Vishay Document 88303 and defines the upper voltage limit imposed on protected circuits during surge events. The 1.5SMC16AHM3/I maintains this clamping performance across its specified operating temperature range.
Is the 1.5SMC16AHM3/I qualified for automotive applications?
Yes, the 1.5SMC16AHM3/I carries the HM3 suffix, confirming it is halogen-free, RoHS-compliant, and fully qualified to AEC-Q101 for automotive use. This includes passing stress tests for temperature cycling, high-temperature operating life, and mechanical shock-making the 1.5SMC16AHM3/I suitable for under-hood and chassis-mounted electronic control units.
What does the "I" suffix indicate in the 1.5SMC16AHM3/I part number?
The "I" suffix in 1.5SMC16AHM3/I denotes packaging in 13-inch diameter plastic tape and reel, with a standard quantity of 3500 units per reel. This format supports high-volume automated SMT placement and is distinct from the "H" suffix (7-inch reel, 850 units). Both share identical electrical and reliability specifications.
How does the thermal resistance of the 1.5SMC16AHM3/I affect PCB layout?
The 1.5SMC16AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. To maintain safe junction temperatures during repetitive surges, designers must provide adequate copper area and avoid excessive trace length-especially for the cathode connection, which carries full surge current. The 1.5SMC16AHM3/I's RθJA assumes minimum recommended pad layout per Vishay's outline drawing.
What is the reverse leakage current of the 1.5SMC16AHM3/I at its maximum stand-off voltage?
At its maximum stand-off voltage of 13.6 V and ambient temperature of 25 °C, the 1.5SMC16AHM3/I exhibits a maximum reverse leakage current (ID) of 1.0 μA. This ultra-low leakage ensures minimal power loss in always-on systems and prevents unintended biasing of sensitive analog front-ends-critical for battery-powered sensor nodes and precision measurement circuits using the 1.5SMC16AHM3/I.
