Product details
Overview
6DFN16CA-M3/I from Vishay General Semiconductor is a bidirectional surface-mount TRANSZORB® transient voltage suppressor in DFN3820A package, with 16.0 V nominal breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 22.5 V max clamping voltage at 26.7 A peak pulse current, and 600 W peak pulse power (10/1000 μs). It protects signal lines in sensor units and MOSFET gates against lightning-induced transients and inductive switching surges.
For engineers reviewing the 6DFN16CA-M3/I datasheet, 6DFN16CA-M3/I pinout, 6DFN16CA-M3/I application, or 6DFN16CA-M3/I equivalent, key selection criteria include clamping performance at 26.7 A, thermal resistance (RθJA = 140–175 °C/W), bidirectional polarity, MSL Level 1 rating, and compatibility with AOI inspection due to side-wettable flanks.
Technical Context
This device uses passivated anisotropic rectifier technology optimized for junction passivation and low-leakage transient suppression. Its single-element, bidirectional configuration delivers symmetrical clamping behavior across both polarities without cathode marking.
Designed for automated SMT placement, it features a halogen-free, RoHS-compliant matte tin-plated DFN3820A package with 0.88 mm typical height and JEDEC-compliant thermal characteristics (RθJM = 5–6.5 °C/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (Nominal) | 16.0 V - Ensures reliable conduction onset above 13.6 V operating voltage, minimizing false triggering. |
| VWM | 13.6 V - Maximum continuous reverse voltage before leakage exceeds 1.0 μA at 25 °C. |
| VC @ IPPM | 22.5 V - Clamps surge to safe level during 26.7 A 10/1000 μs pulse, protecting downstream ICs. |
| PPPM | 600 W - Withstands high-energy transients common in industrial and telecom surge environments. |
| TJ max | +175 °C - Enables operation in under-hood automotive or high-temperature industrial enclosures. |

| Low-profile height (0.88 mm) | Supports ultra-thin end equipment such as portable medical sensors and slim industrial controllers. |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow without dry-packaging or baking requirements. |
| Halogen-free & RoHS-compliant (M3) | Fulfills environmental compliance for global OEMs while maintaining thermal and electrical performance. |
| Junction passivation design | Reduces leakage current to ≤1.0 μA at VWM, preserving signal integrity in high-impedance sensor interfaces. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load-dump and ISO 7637-2 pulses. IC Role / Device Role: Primary TVS clamp placed directly at connector entry point to shunt surge energy before reaching interface ICs. Use Value: 22.5 V clamping voltage ensures microcontroller GPIOs and transceiver inputs remain below absolute maximum ratings during 26.7 A transients. | Use Scenario: Safeguarding digital input modules in programmable logic controllers exposed to relay coil flyback and motor drive noise. IC Role / Device Role: Bidirectional transient suppressor across isolated 24 V DC input lines to prevent latch-up or damage to optocouplers and Schmitt triggers. Use Value: 600 W peak power rating sustains repeated 10/1000 μs surges without degradation, supporting long-term field reliability. |
| Medical Wearable ESD Shielding | Telecom Base Station Interface |
Use Scenario: ESD protection for biopotential electrode inputs in wearable ECG monitors subjected to ±30 kV human-body-model discharges. IC Role / Device Role: First-line defense at front-end analog signal path, placed before instrumentation amplifier inputs. Use Value: 1.0 μA leakage at 13.6 V preserves high-impedance node accuracy and minimizes offset drift in precision measurement circuits. | Use Scenario: Surge protection on RS-485/RS-232 data lines connecting remote radio units to baseband processors in outdoor telecom cabinets. IC Role / Device Role: DFN-packaged TVS mounted adjacent to connector to minimize trace inductance and improve clamping response. Use Value: DFN3820A's 2.18 mm × 1.98 mm footprint allows dense placement near high-speed connectors without compromising board space. |
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-E3/57T | DO-214AC package; higher RθJA (~150 °C/W); 16 V VBR, 23.2 V VC @ 25.8 A; unidirectional only. | Requires polarity-aware layout; less suitable for bidirectional AC-coupled lines or differential buses. | Select when legacy through-hole or larger SMT footprint is acceptable and unidirectional clamping suffices. |
| SMCJ16CA | DO-214AB package; 16 V VBR, 25.6 V VC @ 23.4 A; same bidirectional function but 7.11 mm × 6.22 mm footprint. | Higher clamping voltage reduces margin for sensitive 3.3 V/5 V logic; not AOI-optimized. | Choose for cost-sensitive industrial designs where board space and AOI are not constraints. |
Compared with SMAJ16A-E3/57T and SMCJ16CA, the 6DFN16CA-M3/I offers superior board-area efficiency, lower clamping voltage, and built-in AOI support-critical for high-volume, miniaturized, and automated production of sensor and telecom interfaces.

FAQ
What is the clamping voltage of the 6DFN16CA-M3/I at its rated peak pulse current?
The 6DFN16CA-M3/I has a maximum clamping voltage (VC) of 22.5 V at its rated peak pulse current (IPPM) of 26.7 A under a 10/1000 μs waveform. This value is measured per Figure 3 in the official Vishay datasheet (Doc. #98490) and ensures downstream components remain within safe operating limits during surge events.
Is the 6DFN16CA-M3/I suitable for bidirectional signal line protection?
Yes, the 6DFN16CA-M3/I is explicitly designed as a bidirectional TVS diode with no cathode marking, enabling symmetrical clamping on AC-coupled or differential lines such as RS-485, CAN, or audio interfaces. Its CA suffix denotes ±5 % VBR tolerance and bidirectional functionality, confirmed in the Electrical Characteristics table of the Vishay datasheet.
Does the 6DFN16CA-M3/I meet moisture sensitivity level (MSL) requirements for standard reflow?
Yes, the 6DFN16CA-M3/I meets J-STD-020 MSL Level 1 with a maximum peak reflow temperature of 260 °C. This eliminates the need for dry-packing or baking prior to assembly, simplifying manufacturing flow and supporting unlimited floor life-verified in the Mechanical Data section of Vishay document 98490.
What is the thermal resistance junction-to-ambient (RθJA) for the 6DFN16CA-M3/I?
The 6DFN16CA-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. This value is specified in the Thermal Characteristics table (page 3) of the Vishay datasheet and reflects performance under defined 2 oz. copper pad conditions.
How does the DFN3820A package of the 6DFN16CA-M3/I support automated optical inspection (AOI)?
The DFN3820A package of the 6DFN16CA-M3/I features side-wettable flanks-exposed metal on the vertical edges of the terminals-that allow AOI systems to verify solder fillet formation without X-ray. This capability is explicitly cited in the FEATURES section of the Vishay datasheet and supports high-yield, high-volume SMT production.
