Product details
Overview
6DFN30CA-M3/H 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), and 600 W peak pulse power (10/1000 μs). It clamps transients to ≤41.4 V at 14.5 A peak surge current and operates from –65 °C to +175 °C - deployed for ESD and lightning surge protection on sensor signal lines in industrial and automotive control modules.
For engineers reviewing the 6DFN30CA-M3/H datasheet, 6DFN30CA-M3/H pinout, 6DFN30CA-M3/H application, or 6DFN30CA-M3/H equivalent, this page delivers verified electrical specs, thermal resistance (RθJA = 140–175 °C/W), IEC 61000-4-2 ±30 kV ESD immunity, MSL Level 1 rating, and side-wettable flanks for AOI-compatible automated assembly.
Technical Context
This device implements an anisotropic rectifier structure with junction passivation optimized for low-leakage bidirectional clamping. Its single-channel DFN3820A configuration delivers symmetrical reverse standoff and clamping behavior without polarity marking, enabling direct placement across differential or unidirectional signal paths requiring robust transient suppression.
Designed for high-reliability automated SMT processes, it features matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102, passes JESD 201 Class 2 whisker testing, and meets UL 94 V-0 flammability - all while maintaining 0.88 mm profile height for space-constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 28.5 / 30.0 / 31.5 V - ensures reliable triggering above system operating voltage with ±5 % tolerance |
| VWM | 25.6 V - maximum continuous working voltage before leakage exceeds 1 μA at 25 °C |
| IPPM (10/1000 μs) | 14.5 A - peak surge current capability enabling 600 W transient absorption per JEDEC standard |
| VC @ IPPM | 41.4 V - clamped voltage during full surge, limiting stress on downstream ICs or MOSFETs |
| TJ max | +175 °C - supports operation in under-hood automotive or industrial motor drive environments |

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 ESD events in engine control units. IC Role / Device Role / Timing Role: Bidirectional TVS placed directly at connector or IC input pins to clamp fast transients before they reach sensitive analog front-ends. Use Value: Limits clamping voltage to 41.4 V at 14.5 A, preventing latch-up or gate oxide damage in 3.3 V/5 V microcontrollers and signal conditioners. | Use Scenario: Safeguarding digital input/output channels of programmable logic controllers against inductive switching surges from solenoids and relays. IC Role / Device Role / Timing Role: Standoff-rated transient suppressor mounted at field-side interface to absorb 600 W pulses without degradation over >100,000 cycles. Use Value: Maintains 25.6 V working voltage margin while surviving repeated 10/1000 μs surges up to 14.5 A - validated per IEC 61000-4-5. |
| Medical Imaging Signal Integrity | Telecom Line Interface Protection |
Use Scenario: Shielding low-noise analog signal paths in ultrasound or MRI front-end ASICs from ESD and coupling noise during cable handling. IC Role / Device Role / Timing Role: Low-capacitance (<50 pF typical at 0 V) bidirectional suppressor placed adjacent to ADC inputs to minimize signal distortion. Use Value: Delivers ±30 kV IEC 61000-4-2 immunity without adding measurable capacitance-induced phase shift or bandwidth loss. | Use Scenario: Front-end protection of Ethernet PHYs and DSL line drivers exposed to lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Primary surge limiter in hybrid protection circuits, coordinated with GDTs or PTCs to handle multi-stroke events. Use Value: Withstands 175 °C junction temperature and maintains clamping performance after repeated 600 W pulses - critical for telecom infrastructure uptime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30CA | DO-214AC package, 1.9 mm height, higher RθJA (~190 °C/W), same VBR/VWM/PPPM | Less suitable for ultra-thin designs or AOI-dependent production; requires larger PCB footprint | Select when legacy through-hole or larger SMT footprint is acceptable and thermal budget allows higher junction rise |
| SMCJ30CA | DO-214AB package, 2.6 mm height, 1500 W rating, higher VC (48.4 V), same polarity | Used where higher energy absorption is needed but board space and height are less constrained | Choose only if system-level surge tests exceed 600 W - otherwise over-spec'd and cost-inefficient for 6DFN30CA-M3/H's target use cases |
Compared with SMAJ30CA and SMCJ30CA, the 6DFN30CA-M3/H offers superior board-area efficiency, AOI compatibility, and thermal performance per unit volume - making it optimal for next-generation compact, high-reliability sensor and communication modules.

FAQ
What is the exact breakdown voltage range for 6DFN30CA-M3/H?
The 6DFN30CA-M3/H has a guaranteed breakdown voltage (VBR) range of 28.5 V to 31.5 V at 1.0 mA test current, per the Vishay datasheet revision dated 17-Oct-2023. This ±5 % tolerance is inherent to its CA-grade bidirectional construction and is measured under standardized conditions - not extrapolated or estimated. The 6DFN30CA-M3/H maintains this specification across its full operating temperature range.
Does 6DFN30CA-M3/H require a cathode marking for orientation during placement?
No - the 6DFN30CA-M3/H is a bidirectional TVS and carries no cathode band or polarity marking. Both terminals are functionally identical, allowing unrestricted orientation during automated placement. This eliminates orientation errors in high-speed SMT lines and simplifies layout design, as confirmed in the "Polarity" note of the Vishay 98490 datasheet.
Is 6DFN30CA-M3/H qualified to AEC-Q101?
Yes - the "H" suffix in 6DFN30CA-M3/H denotes AEC-Q101 qualification per the Vishay ordering information table. This includes stress testing for temperature cycling, humidity bias, and ESD robustness specific to automotive electronic components. The 6DFN30CA-M3/H is certified for use in automotive powertrain and body electronics where reliability under harsh environmental conditions is required.
What is the thermal resistance junction-to-ambient (RθJA) for 6DFN30CA-M3/H?
The 6DFN30CA-M3/H 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 value is measured using the recommended DFN3820A mounting pad layout and directly impacts derating curves for repetitive surge events - critical for thermal design validation in the 6DFN30CA-M3/H's target applications.
Can 6DFN30CA-M3/H be used in place of SMAJ30CA without PCB redesign?
No - the 6DFN30CA-M3/H uses a DFN3820A footprint (3.95 mm × 2.18 mm), while SMAJ30CA uses DO-214AC (4.5 mm × 2.7 mm) with different pad geometry and terminal spacing. Although both provide comparable electrical protection, the 6DFN30CA-M3/H requires dedicated layout and stencil design. Direct substitution would necessitate PCB revision and requalification of solder joint integrity and thermal performance.
