Product details
Overview
TPC16CAHM3/I from Vishay General Semiconductor is a bidirectional 1500 W transient voltage suppressor (TVS) in the SMPC (TO-277A) surface-mount package, designed for high-reliability automotive and industrial electronics protection. It features a standoff voltage of 13.6 V, breakdown voltage range of 15.2–16.8 V at 1 mA, clamping voltage of 22.5 V at 66.7 A, and operates up to +185 °C junction temperature.
For engineers reviewing the TPC16CAHM3/I datasheet, TPC16CAHM3/I pinout, TPC16CAHM3/I application, or TPC16CAHM3/I equivalent, key selection criteria include its AEC-Q101 qualification, MSL Level 1 rating, low-profile 1.1 mm height, bidirectional surge suppression capability, and compatibility with automated SMT placement on automotive sensor signal lines and MOSFET gate drivers.
Technical Context
The TPC16CAHM3/I implements a junction-passivated PAR® design optimized for fast transient response and stable clamping under repetitive 10/1000 μs surge waveforms. Its bidirectional structure enables symmetrical protection without polarity sensitivity, and it maintains specified electrical performance across -65 °C to +185 °C operating junction temperature.
Rated for 1500 W peak pulse power per ANSI/IEEE C62.35, the device delivers 66.7 A peak pulse current with ≤22.5 V clamping voltage while exhibiting ≤1.0 μA reverse leakage at 13.6 V standoff. It meets JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1 reflow requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15CA | Lower PPPM (400 W), SMA package (higher thermal resistance), VWM = 15.0 V, VC = 24.4 V @ 24.4 A | Not AEC-Q101 qualified; limited to consumer/industrial use; less suitable for under-hood automotive | Select when cost-sensitive non-automotive designs require basic 15 V clamping with legacy SMA footprint |
| TPC16CAHM3/H | Identical electrical specs and package; differs only in tape-and-reel packaging (7" vs. 13" reel, 1500 vs. 6500 units) | No functional or application difference; same PCB layout, thermal, and electrical behavior | Choose based on production volume and SMT line feeder compatibility-not for performance differentiation |
Compared with SMAJ15CA and TPC16CAHM3/H, the TPC16CAHM3/I offers superior automotive qualification, higher surge robustness (1500 W vs. 400 W), and lower clamping voltage (22.5 V vs. 24.4 V), while sharing identical form-factor and electrical behavior with TPC16CAHM3/H except for reel size and quantity.

FAQ
What is the maximum clamping voltage of the TPC16CAHM3/I under a 10/1000 μs surge?
The TPC16CAHM3/I has a maximum clamping voltage (VC) of 22.5 V when subjected to its rated peak pulse current of 66.7 A under the standardized 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures protected downstream components remain within safe voltage limits during transient events.
Is the TPC16CAHM3/I qualified for automotive applications?
Yes, the TPC16CAHM3/I is AEC-Q101 qualified and carries the HM3 suffix indicating full compliance with automotive stress test requirements, including temperature cycling, humidity bias, and mechanical shock. Its +185 °C junction rating and MSL Level 1 reflow capability further validate its suitability for under-hood and body-control module applications.
What does the "HM3" suffix mean in TPC16CAHM3/I?
The "HM3" suffix in TPC16CAHM3/I denotes Vishay's halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance and AEC-Q101 qualification. The "I" indicates 13-inch tape-and-reel packaging containing 6500 units, distinguishing it from the "H" variant (7-inch reel, 1500 units).
Can the TPC16CAHM3/I replace SMAJ15CA in an existing design?
The TPC16CAHM3/I is not a direct drop-in replacement for SMAJ15CA due to different package (SMPC vs. SMA), thermal profile, and surge rating (1500 W vs. 400 W). While both are bidirectional 15 V-class TVS diodes, PCB layout, thermal relief, and system-level surge margin must be revalidated before substitution.
What is the reverse leakage current specification for TPC16CAHM3/I at its standoff voltage?
The TPC16CAHM3/I exhibits a maximum reverse leakage current (ID) of 1.0 μA at its standoff voltage (VWM) of 13.6 V, measured at TA = 25 °C. This low leakage supports energy-efficient designs in battery-powered and always-on automotive subsystems where standby current is tightly constrained.
