Product details
Overview
6DFN27CA-M3/H from Vishay General Semiconductor is a bidirectional surface-mount TRANSZORB® transient voltage suppressor in DFN3820A package, featuring 27.0 V nominal breakdown voltage (VBR), 23.1 V stand-off voltage (VWM), 37.5 V maximum clamping voltage (VC) at 16.0 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 6DFN27CA-M3/H datasheet, 6DFN27CA-M3/H pinout, 6DFN27CA-M3/H application, or 6DFN27CA-M3/H equivalent, this page delivers verified electrical parameters, thermal resistance values (RθJA = 140–175 °C/W), ESD immunity (30 kV contact/air), and precise DFN3820A mechanical dimensions for PCB layout and AOI validation.
Technical Context
This device uses passivated anisotropic rectifier technology to achieve bidirectional clamping with low leakage (<1.0 μA at VWM) and stable breakdown tolerance of ±5 % across -65 °C to +175 °C operating junction temperature. Its DFN3820A package enables automated placement and supports AOI via side-wettable flanks.
The 6DFN27CA-M3/H delivers 37.5 V clamping at 16.0 A (10/1000 μs), with thermal resistance junction-to-mount (RθJM) as low as 5 °C/W, enabling effective heat dissipation on FR4 PCBs. It meets MSL Level 1 per J-STD-020 and passes JESD 201 Class 2 whisker testing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ28A-E3/5AT | DO-214AC (SMA) package; 28 V VBR; 400 W PPPM; higher RθJA (~190 °C/W) | Larger footprint; less suitable for high-density layouts or AOI-dependent production | Choose when legacy SMA footprint compatibility is required and thermal budget permits higher junction rise |
| SMCJ28A | DO-214AB (SMC) package; 28 V VBR; 1500 W PPPM; 3× larger body size | Higher power handling but incompatible with space-constrained designs and automated optical inspection | Select only if system-level surge requirements exceed 600 W and board area is not constrained |
Compared with SMAJ28A-E3/5AT and SMCJ28A, the 6DFN27CA-M3/H offers superior board-space efficiency, AOI-ready side-wettable flanks, and lower thermal resistance (RθJA down to 140 °C/W), making it optimal for modern high-density automotive and industrial PCBs where layout density and process automation are critical.

FAQ
What is the breakdown voltage tolerance of the 6DFN27CA-M3/H?
The 6DFN27CA-M3/H has a breakdown voltage tolerance of ±5 %, with a nominal VBR of 27.0 V and specified minimum/maximum values of 25.7 V and 28.4 V respectively at 1.0 mA test current. This tight tolerance ensures predictable clamping behavior across production lots and temperature ranges, critical for consistent overvoltage protection in safety-critical systems.
Does the 6DFN27CA-M3/H require a cathode marking for PCB layout?
No - the 6DFN27CA-M3/H is a bidirectional TVS and carries no cathode band or polarity marking. Its DFN3820A package features two identical terminals, allowing symmetrical placement on PCBs without orientation constraints. This simplifies layout, reduces assembly errors, and supports AC-coupled or differential signal protection without directional routing concerns.
What is the maximum operating temperature for the 6DFN27CA-M3/H?
The 6DFN27CA-M3/H supports an operating junction temperature range of -65 °C to +175 °C. Its 175 °C TJmax rating enables deployment in under-hood automotive modules, industrial motor drives, and telecom equipment exposed to elevated ambient temperatures, provided thermal design accounts for RθJA (140–175 °C/W) and derating curves per Figure 2.
Is the 6DFN27CA-M3/H compatible with lead-free reflow processes?
Yes - the 6DFN27CA-M3/H is rated for lead-free reflow with a maximum peak temperature of 260 °C per J-STD-020 MSL Level 1, and its matte tin-plated terminations comply with J-STD-002 and JESD 22-B102 solderability standards. The M3 suffix confirms halogen-free, RoHS-compliant construction and JESD 201 Class 2 whisker resistance.
How does the 6DFN27CA-M3/H perform under ESD stress?
The 6DFN27CA-M3/H achieves 30 kV ESD immunity per IEC 61000-4-2 for both contact and air discharge tests. This level of protection is validated at the device level and ensures robustness against common handling and system-level ESD events in end-user environments, particularly in handheld medical devices and field-deployed industrial sensors.
