Product details
Overview
6DFN62CA-M3/H from Vishay General Semiconductor is a bidirectional surface-mount TRANSZORB® transient voltage suppressor in DFN3820A package, featuring 62 V nominal breakdown voltage (VBR = 58.9–65.1 V), 53.0 V stand-off voltage (VWM), and 600 W peak pulse power (10/1000 μs). It delivers 7.1 A peak pulse current and clamps to 85.0 V at IPPM, protecting sensitive ICs and MOSFETs in industrial sensor signal lines.
For engineers reviewing the 6DFN62CA-M3/H datasheet, 6DFN62CA-M3/H pinout, 6DFN62CA-M3/H application, or 6DFN62CA-M3/H equivalent, key selection criteria include bidirectional clamping capability, MSL Level 1 moisture sensitivity, side-wettable flanks for AOI, halogen-free RoHS-compliant construction, and AEC-Q101 qualification indicated by the "H" suffix.
Technical Context
This TVS diode employs anisotropic rectifier technology with junction passivation optimized for low-leakage, high-reliability transient suppression. Its bidirectional configuration enables symmetrical clamping on both polarities without polarity marking, supporting AC-coupled or differential signal protection.
The DFN3820A package provides thermal resistance RθJA of 140–175 °C/W and RθJM of 5–6.5 °C/W, enabling effective heat dissipation in compact PCB layouts. It meets IEC 61000-4-2 ESD immunity up to ±30 kV (contact/air discharge) and operates across -65 °C to +175 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

IC Role / Device Role / Timing Role: Primary transient suppressor on LIN data line and power rail inputs, meeting ISO 7637-2 Pulse 1/2/5a immunity requirements. Use Value: Clamps to ≤85 V within nanoseconds, preserving signal integrity and ensuring uninterrupted communication during 12 V system surges up to 7.1 A. |
| Telecom Power Interface | Medical Imaging Equipment |
|

Use Scenario: Protecting high-speed analog front-ends (AFE) in ultrasound probe cables and MRI subsystems from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance (<50 pF typical at VWM) bidirectional clamp on differential sensor traces near connector interface. Use Value: Maintains signal fidelity with minimal distortion due to low junction capacitance and fast response time (<1 ns), critical for RF-sensitive imaging paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A-E3/57T | DO-214AC (SMA) package, 64 V VBR, 400 W PPPM, unidirectional, higher RθJA (~190 °C/W) | Larger footprint, requires polarity-aware layout; lower surge rating limits use in high-energy industrial environments | Select when legacy SMA footprint compatibility is required and 400 W rating suffices; not drop-in due to unidirectionality and package mismatch |
| SMCJ64A | DO-214AB (SMC) package, 64 V VBR, 1500 W PPPM, unidirectional, 2.5 mm height | Higher power handling but 3× taller profile; unsuitable for ultra-low-profile designs and AOI-dependent production | Choose for extreme surge environments where 1500 W is mandatory; avoid if board height <1.0 mm or AOI inspection is enforced |
Compared with SMAJ64A-E3/57T and SMCJ64A, the 6DFN62CA-M3/H offers superior board-space efficiency, AOI-ready side-wettable flanks, and AEC-Q101 qualification - making it optimal for next-gen compact, automotive-grade, and high-yield SMT designs where 600 W clamping performance is sufficient.

FAQ
What does the "H" suffix in 6DFN62CA-M3/H indicate?
The "H" suffix in 6DFN62CA-M3/H denotes AEC-Q101 qualification, confirming that the 6DFN62CA-M3/H has passed rigorous automotive-grade stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing. This makes the 6DFN62CA-M3/H suitable for under-hood and body electronics applications where reliability is mission-critical.
Is 6DFN62CA-M3/H unidirectional or bidirectional?
The 6DFN62CA-M3/H is a bidirectional TVS diode, as confirmed by its "CA" designation (C = ±5 % tolerance, A = bidirectional) and absence of cathode marking. It provides symmetrical clamping for both positive and negative transients, eliminating polarity concerns during placement and enabling use in AC-coupled or differential signal paths without orientation constraints.
What is the maximum clamping voltage of 6DFN62CA-M3/H at rated surge current?
The maximum clamping voltage (VC) of the 6DFN62CA-M3/H is 85.0 V when subjected to its rated peak pulse current (IPPM) of 7.1 A under the standard 10/1000 μs waveform. This value is measured per Figure 3 in the datasheet and ensures downstream components experience controlled overvoltage stress during transient events.
Does 6DFN62CA-M3/H require special PCB layout considerations?
Yes - the 6DFN62CA-M3/H uses a DFN3820A package with side-wettable flanks, so the PCB pad layout must follow Vishay's recommended mounting footprint (Document 98490, page 5) to ensure proper solder fillet formation for AOI. Thermal relief and copper pour under the thermal pad are discouraged; instead, use isolated thermal vias to inner ground planes to manage RθJM.
How does the M3 suffix affect the environmental compliance of 6DFN62CA-M3/H?
The M3 suffix in 6DFN62CA-M3/H certifies halogen-free, RoHS-compliant, and Pb-free construction, meeting JEDEC JESD201 Class 2 whisker resistance and IPC/JEDEC J-STD-020 MSL Level 1 requirements. This ensures the 6DFN62CA-M3/H is compatible with lead-free reflow profiles up to 260 °C and supports sustainable manufacturing and end-of-life recycling mandates globally.
