Product details
Overview
6DFN30CA-M3/I from Vishay General Semiconductor is a bidirectional surface-mount TRANSZORB® transient voltage suppressor in DFN3820A package, with 30 V nominal breakdown voltage (VBR = 28.5–31.5 V), 25.6 V stand-off voltage (VWM), 41.4 V max clamping voltage at 14.5 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 6DFN30CA-M3/I datasheet, 6DFN30CA-M3/I pinout, 6DFN30CA-M3/I application, or 6DFN30CA-M3/I equivalent, this page delivers verified electrical specs, thermal derating behavior, ESD immunity (30 kV contact/air), package dimensions, and real-world protection use cases - all aligned to Vishay Document #98490 (Rev. 17-Oct-2023).
Technical Context
This device uses anisotropic rectifier technology with junction passivation for stable bidirectional clamping. Its single-channel configuration operates across -65 °C to +175 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak.
Clamping performance is defined by a 10/1000 μs waveform, with thermal resistance RθJA up to 175 °C/W (FR4, 2 oz copper) and RθJM as low as 5 °C/W (mount interface). It delivers 30 kV IEC 61000-4-2 ESD immunity and exhibits ≤1.0 μA reverse leakage at VWM and 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 28.5 / 30.0 / 31.5 V - ensures reliable conduction onset above system operating voltage while accommodating ±5 % tolerance |
| VWM | 25.6 V - maximum continuous reverse voltage before significant leakage; sets safe margin below VBR |
| VC @ IPPM | 41.4 V - clamped voltage during 14.5 A surge; defines worst-case overvoltage seen by protected IC |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A-E3/57T | DO-214AC package; 30 V VWM; 48.4 V VC @ 12.3 A; higher clamping voltage and larger footprint | Less suitable for ultra-thin or high-density layouts due to 2.4 mm height and 4.3 mm length | Select when legacy through-hole or larger SMT footprint is acceptable and lower cost per unit is prioritized |
| SMCJ33A | DO-214AB package; 33 V VWM; 53.3 V VC @ 11.3 A; 1500 W rating but 7.1 mm × 6.2 mm size | Used where higher surge margin is required but board space is not constrained | Choose for applications needing >1000 W surge handling and where thermal mass from larger package improves long-pulse robustness |
Compared with SMAJ30A-E3/57T and SMCJ33A, the 6DFN30CA-M3/I offers superior board-space efficiency (3.95 mm × 2.18 mm), lower profile (0.88 mm), and tighter clamping (41.4 V vs. ≥48.4 V), making it optimal for miniaturized, thermally dense designs requiring precise voltage limiting.

FAQ
What is the breakdown voltage tolerance of the 6DFN30CA-M3/I?
The 6DFN30CA-M3/I has a ±5 % breakdown voltage tolerance, specified as 28.5 V (min) to 31.5 V (max) at 1.0 mA test current. This tight tolerance ensures predictable clamping onset across production lots and supports robust design margins in 24 V system interfaces where overvoltage must be tightly bounded.
Does the 6DFN30CA-M3/I require a cathode marking for orientation?
No - the 6DFN30CA-M3/I is a bidirectional TVS and carries no cathode band or polarity marking. Its symmetrical DFN3820A package features identical terminals, allowing placement in either orientation without affecting clamping performance or circuit function.
What is the maximum allowable junction temperature for continuous operation of the 6DFN30CA-M3/I?
The 6DFN30CA-M3/I supports continuous operation up to +175 °C junction temperature, as confirmed in Vishay Document #98490. This rating enables use in high-ambient environments such as automotive powertrain modules, industrial motor drives, and enclosed telecom enclosures without derating concerns below that limit.
How does the 6DFN30CA-M3/I perform under high-temperature reverse leakage conditions?
At 150 °C junction temperature, the 6DFN30CA-M3/I maintains ≤1.0 μA maximum reverse leakage at its 25.6 V stand-off voltage. This low, temperature-stable leakage preserves signal integrity in precision analog paths and avoids false triggering in high-impedance monitoring circuits.
Is the 6DFN30CA-M3/I compatible with standard SMT reflow profiles?
Yes - the 6DFN30CA-M3/I is rated MSL Level 1 per J-STD-020 and qualified for peak reflow temperatures up to 260 °C. No pre-baking is required, and it supports standard lead-free reflow profiles used for FR4 PCBs with 2 oz copper, making it compatible with high-volume automated assembly lines.
