Product details
Overview
6DFN16A-M3/I from Vishay General Semiconductor is a unidirectional surface-mount TRANSZORB® transient voltage suppressor in DFN3820A package, with 16.0 V nominal breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 μs), and 22.5 V maximum clamping voltage at 26.7 A peak pulse current - deployed for ESD and surge protection on signal lines of sensor units and MOSFET gate drivers in industrial and automotive electronics.
For engineers reviewing the 6DFN16A-M3/I datasheet, 6DFN16A-M3/I pinout, 6DFN16A-M3/I application, or 6DFN16A-M3/I equivalent, key selection criteria include clamping performance under 10/1000 μs transients, thermal resistance (RθJA = 140–175 °C/W), MSL Level 1 moisture sensitivity, and side-wettable flank compatibility with automated optical inspection (AOI) and reflow soldering.
Technical Context
This device implements an anisotropic rectifier structure with junction passivation optimized for low-leakage transient suppression. It delivers unidirectional clamping with 1.0 mA test current, 1.0 μA max reverse leakage at VWM, and 0.078 %/°C temperature coefficient of VBR.
Designed for single-line protection, it operates across -65 °C to +175 °C junction temperature range and meets IEC 61000-4-2 ±30 kV contact/air discharge requirements. Its DFN3820A footprint enables high-density PCB layouts while maintaining thermal performance via low RθJM (5–6.5 °C/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 15.2 / 16.0 / 16.8 V - ensures reliable conduction onset above circuit operating voltage without false triggering |
| VWM | 13.6 V - maximum continuous reverse voltage before leakage exceeds 1.0 μA, compatible with 12 V rail systems |
| IPPM | 26.7 A (10/1000 μs) - defines surge current handling capacity before clamping voltage exceeds 22.5 V |
| VC | 22.5 V - maximum clamped voltage during rated surge, limiting stress on downstream ICs |
| PPPM | 600 W - peak transient energy absorption capability under standardized 10/1000 μs waveform |
| TJ max | +175 °C - enables operation in under-hood or high-temperature industrial environments |
| RθJA | 140–175 °C/W - determines thermal derating slope on standard FR4 PCB; impacts sustained surge duty cycle |
Pinout & Package

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 | DO-214AC (SMA) package, 1.85 mm height, RθJA ≈ 50 °C/W higher, same VBR/VC specs | Less suitable for high-density SMT layouts; requires larger PCB area and lacks side-wettable flanks for AOI | Select SMAJ16A only if legacy through-hole or mixed-technology assembly is required and thermal derating margin permits |
| SMCJ16A | DO-214AB (SMC) package, 2.3 mm height, 1500 W PPPM, higher VC (25.3 V), lower leakage tolerance at high TJ | Better for higher-energy surges but over-specified for compact 600 W applications; incompatible with space-constrained modules | Choose SMCJ16A only when system-level testing confirms need for >600 W rating and board layout accommodates larger footprint |
Compared with SMAJ16A and SMCJ16A, the 6DFN16A-M3/I offers superior board-area efficiency, AOI-ready solder joints, and tighter thermal management in modern high-density designs - making it optimal for new industrial and automotive platforms where miniaturization and process automation are critical.

FAQ
What is the maximum clamping voltage of the 6DFN16A-M3/I under rated surge conditions?
The 6DFN16A-M3/I exhibits a maximum clamping voltage (VC) of 22.5 V when subjected to its rated 26.7 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within safe operating limits.
Does the 6DFN16A-M3/I meet automotive qualification standards?
The 6DFN16A-M3/I carries the M3 suffix indicating halogen-free, RoHS-compliant, and industrial-grade construction per Vishay's internal specifications. It is not AEC-Q101 qualified (which would require 'H' suffix); therefore, the 6DFN16A-M3/I is intended for industrial, medical, and telecom applications - not automotive safety-critical systems unless validated per customer-specific qualification protocols.
How does the DFN3820A package of the 6DFN16A-M3/I support automated optical inspection (AOI)?
The 6DFN16A-M3/I uses a DFN3820A package with side-wettable flanks - meaning solder extends visibly up the vertical sidewalls of the terminals during reflow. This geometry allows standard AOI systems to inspect solder fillet shape, coverage, and coplanarity without requiring X-ray, improving first-pass yield and reducing post-reflow defect escapes in high-volume SMT lines.
What is the thermal resistance junction-to-ambient (RθJA) for the 6DFN16A-M3/I?
The 6DFN16A-M3/I has a typical RθJA of 140 °C/W and a maximum of 175 °C/W when mounted on a standard FR4 PCB per JEDEC 51-2A guidelines. This parameter governs how much the junction temperature rises above ambient per watt of dissipated power - essential for calculating safe surge repetition rates and long-term reliability in thermally constrained enclosures.
Can the 6DFN16A-M3/I be used for bidirectional transient suppression?
No - the 6DFN16A-M3/I is explicitly a unidirectional TVS device, as confirmed by its polarity designation ('A' suffix), cathode marking, and electrical characteristics table showing only positive VBR and VWM. For bidirectional protection, a separate part such as 6DFN16CA (if available in this family) or dual-series configuration would be required; the 6DFN16A-M3/I must be oriented correctly with cathode toward the protected line.
