Product details
Overview
T6N16CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, featuring 16.0 V nominal breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), and 600 W peak pulse power (10/1000 μs), designed for automotive-grade ESD and surge protection of sensor signal lines and MOSFET gates.
For engineers reviewing the T6N16CAHM3/I datasheet, T6N16CAHM3/I pinout, T6N16CAHM3/I application, or T6N16CAHM3/I equivalent, this AEC-Q101 qualified TVS offers verified 185 °C junction temperature capability, side-wettable flanks for AOI, and MSL Level 1 reflow compatibility - critical for high-reliability automotive electronics design and production validation.
Technical Context
This device implements passivated anisotropic rectifier technology optimized for low-clamping, bidirectional transient suppression. Its DFN3820A package enables compact PCB layout with thermal resistance RθJA ≤ 175 °C/W and RθJM ≤ 6.5 °C/W, supporting sustained operation up to TJ = 185 °C under automotive thermal stress profiles.
It delivers 22.5 V maximum clamping voltage (VC) at 26.7 A peak pulse current (IPPM), with <1.0 μA reverse leakage at VWM and 6.0 μA at 150 °C - ensuring minimal standby power impact in always-on automotive modules while maintaining robust ESD immunity per IEC 61000-4-2 (±30 kV contact/air).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (Nominal) | 16.0 V - precise breakdown threshold enabling accurate overvoltage triggering without false trips in 12 V automotive systems |
| VWM | 13.6 V - ensures reliable blocking during normal 12 V rail operation with 0.4 V margin to typical battery transients |
| VC @ IPPM | 22.5 V - limits downstream IC voltage stress to safe levels during 600 W surge events |
| IPPM (10/1000 μs) | 26.7 A - sustains high-energy lightning-induced surges per ISO 7637-2 Pulse 3b |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16CAHE3_A/H | DO-214AC (SMA) package, 1.5 mm height, higher RθJA (190 °C/W), same VBR/VC specs | Less suitable for ultra-thin modules; requires larger PCB area and lacks side-wettable flanks for AOI | Select when legacy SMA footprint compatibility is required and board space permits taller profile |
| TPSMD16CA | DO-214AB (SMC) package, 2.3 mm height, 1500 W rating, higher VC (25.5 V), non-AEC-Q101 | Over-specified for 600 W needs; unsuitable for automotive qualification-critical designs | Choose only for industrial applications where cost-per-watt matters more than automotive compliance or footprint density |
Compared with SMAJ16CAHE3_A/H and TPSMD16CA, the T6N16CAHM3/I provides superior board-level integration via its 0.88 mm low-profile DFN3820A package, AEC-Q101 qualification, and AOI-ready side-wettable flanks - making it the optimal choice for next-generation automotive ECUs where space, reliability, and process control are co-constrained.

FAQ
What is the exact breakdown voltage tolerance for T6N16CAHM3/I?
The T6N16CAHM3/I has a breakdown voltage (VBR) tolerance of ±5 %, specified as 15.2 V (min), 16.0 V (nom), and 16.8 V (max) at 1.0 mA test current - confirmed in the Electrical Characteristics table of Vishay document 98489. This tight tolerance ensures consistent clamping behavior across production lots and temperature ranges.
Is T6N16CAHM3/I compatible with lead-free reflow processes?
Yes, T6N16CAHM3/I is fully compatible with lead-free reflow, rated for MSL Level 1 per J-STD-020 and maximum peak temperature of 260 °C. Its matte tin-plated terminals meet J-STD-002 solderability requirements, and the DFN3820A package is qualified for standard Pb-free SMT profiles without delamination or voiding.
Does T6N16CAHM3/I require a heatsink for 600 W surge handling?
No, T6N16CAHM3/I does not require an external heatsink for single-event 600 W (10/1000 μs) surges. Its DFN3820A package achieves RθJM ≤ 6.5 °C/W to the PCB mount pad, and thermal simulations confirm junction temperature remains below 185 °C even on 2 oz. copper FR4 with standard 10 mm² thermal pad - per Figure 5 in document 98489.
How does T6N16CAHM3/I perform at elevated ambient temperatures?
T6N16CAHM3/I maintains full functionality up to +125 °C ambient, with derated surge capability per Figure 2 in document 98489. At TA = 100 °C, it retains >70 % of its 600 W peak pulse power rating, and reverse leakage stays ≤6.0 μA - validated across the -65 °C to +185 °C junction range required by AEC-Q101.
Can T6N16CAHM3/I be used in bidirectional data line protection such as CAN FD?
Yes, T6N16CAHM3/I is suitable for CAN FD physical layer protection due to its bidirectional symmetry, 22.5 V clamping voltage (well below ISO 11898-2 fault voltage limits), and low dynamic capacitance (<100 pF at 0 V). It has been implemented in production automotive gateways for CAN FD transceiver I/O protection without signal integrity degradation.
