Product details
Overview
6DFN16CA-M3/H from Vishay General Semiconductor is a bidirectional surface-mount TRANSZORB® transient voltage suppressor in DFN3820A package, featuring 16.0 V nominal breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 22.5 V maximum clamping voltage at 26.7 A peak pulse current, and 600 W peak pulse power rating (10/1000 μs). It protects sensitive signal lines in sensor units and MOSFET gate drivers against lightning-induced transients and inductive switching surges.
For engineers reviewing the 6DFN16CA-M3/H datasheet, 6DFN16CA-M3/H pinout, 6DFN16CA-M3/H application, or 6DFN16CA-M3/H equivalent, key selection criteria include its bidirectional clamping behavior, low-profile DFN3820A footprint with side-wettable flanks for AOI, 175 °C max junction temperature, and AEC-Q101-qualified H-suffix variant for automotive-grade reliability.
Technical Context
This device employs anisotropic rectifier technology with junction passivation to deliver stable bidirectional clamping across -65 °C to +175 °C operating range. Its DFN3820A package provides 140 °C/W typical junction-to-ambient thermal resistance and meets MSL level 1 per J-STD-020 with 260 °C reflow peak.
The 6DFN16CA-M3/H operates as a single-channel, unidirectional-capable bidirectional TVS - no cathode band marking - with 1.0 mA test current, ≤1.0 μA reverse leakage at VWM, and 30 kV ESD immunity per IEC 61000-4-2 (contact and air discharge).

Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) in vehicle ECUs from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional TVS placed directly at connector interface to clamp fast-rising transients before they reach signal conditioning circuitry. Use Value: 22.5 V clamping voltage ensures MCU GPIOs and transceiver inputs remain below absolute maximum ratings during 26.7 A surges. |
Use Scenario: Safeguarding 24 V digital input modules in programmable logic controllers against field-wiring induced surges and relay coil flyback. IC Role / Device Role / Timing Role: Primary transient suppression element mounted adjacent to terminal block to absorb energy before reaching optocoupler or Schmitt trigger input stage. Use Value: 600 W peak pulse power rating sustains repeated 10/1000 μs surges without degradation in harsh factory environments. |
| Medical Imaging Signal Integrity | Telecom Line Interface Protection |
|
Use Scenario: Shielding low-noise analog front-ends in ultrasound and MRI subsystems from ESD events during probe handling and cable coupling. IC Role / Device Role / Timing Role: Low-capacitance TVS (typ. <100 pF at 0 V) placed inline with differential ADC inputs to preserve signal fidelity. Use Value: 1.0 μA max reverse leakage at 13.6 V VWM prevents DC offset drift in precision medical signal paths. |
Use Scenario: Protecting Ethernet PHYs and PoE-powered devices from lightning-induced surges entering via RJ45 jacks in outdoor telecom cabinets. IC Role / Device Role / Timing Role: First-stage clamping device on data line pairs, coordinated with gas discharge tubes for staged protection architecture. Use Value: 30 kV IEC 61000-4-2 ESD rating eliminates need for secondary ESD diodes in compact telecom module designs. |
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-E3/5A (Vishay) | DO-214AC package, 16 V unidirectional, 400 W PPPM, higher profile (2.3 mm height) | Requires polarity-aware layout; unsuitable for space-constrained DFN-only PCBs | Select when legacy through-hole or larger SMT footprints exist and bidirectionality is not required |
| SMCJ16CA (Littelfuse) | DO-214AB package, 16 V bidirectional, 1500 W PPPM, 7.1 mm × 6.2 mm footprint | Higher surge capacity but 3× larger area; incompatible with fine-pitch DFN routing | Choose for high-energy industrial surge environments where board space permits larger case outline |
Compared with SMAJ16A-E3/5A and SMCJ16CA, the 6DFN16CA-M3/H delivers identical 16 V clamping performance in a 3.95 mm × 2.18 mm footprint with AOI-compatible side-wettable flanks - critical for miniaturized automotive and medical PCBs where height (<0.88 mm) and automated inspection are mandatory.

FAQ
What is the exact breakdown voltage tolerance for 6DFN16CA-M3/H?
The 6DFN16CA-M3/H has a ±5 % breakdown voltage tolerance, confirmed by its "CA" suffix per Vishay's ordering nomenclature. At 25 °C and 1.0 mA test current, VBR is specified as 15.2 V (min), 16.0 V (nom), and 16.8 V (max). This tight tolerance ensures predictable clamping onset across production lots and temperature ranges.
Is 6DFN16CA-M3/H suitable for automotive applications?
Yes, the "H" suffix in 6DFN16CA-M3/H denotes AEC-Q101 qualification per Vishay's ordering information table. It is rated for -65 °C to +175 °C operation, passes MSL level 1 reflow, and features JESD 201 Class 2 whisker resistance - meeting core requirements for under-hood and body-control module deployments.
Does 6DFN16CA-M3/H require a specific PCB pad layout?
Yes, the 6DFN16CA-M3/H requires the DFN3820A mounting pad layout shown in Figure 5 of document 98490: 3.96 mm × 2.20 mm exposed thermal pad with 0.70 mm × 0.86 mm terminal pads and 0.50 mm spacing. Deviation risks solder bridging, insufficient wetting, or thermal derating beyond 140 °C/W.
What is the maximum reverse leakage current for 6DFN16CA-M3/H at 13.6 V?
At VWM = 13.6 V and TA = 25 °C, the maximum reverse leakage current for 6DFN16CA-M3/H is 1.0 μA. At elevated temperature (TJ = 150 °C), leakage remains ≤1.0 μA - verified in the Electrical Characteristics table on page 2 of document 98490 - ensuring minimal power loss in always-on sensor circuits.
How does the side-wettable flank design benefit manufacturing of 6DFN16CA-M3/H?
The side-wettable flanks on the 6DFN16CA-M3/H enable automated optical inspection (AOI) of solder fillets along both long edges of the DFN3820A package. This eliminates manual visual checks, improves first-pass yield in high-volume SMT lines, and complies with IPC-A-610 Class 2/3 acceptance criteria for leadless components.
