Product details
Overview
VS-20CDH02HM3/I from Vishay Semiconductors is a hyperfast dual common-cathode rectifier in SMPD (TO-263AC) package, rated 200 V reverse voltage, 2 × 10 A average forward current per diode, 25 ns typical reverse recovery time at 25 °C, and 0.77 V forward voltage at 10 A and 150 °C junction temperature. It serves as output rectifier in high-frequency SMPS and telecom DC/DC converters.
For engineers reviewing the VS-20CDH02HM3/I datasheet, VS-20CDH02HM3/I pinout, VS-20CDH02HM3/I application, or VS-20CDH02HM3/I equivalent, key selection criteria include hyperfast soft-recovery behavior, AEC-Q101 qualification, 175 °C max junction temperature, low Qrr (25 nC typ.), and SMPD thermal performance with RthJM ≤ 2.4 °C/W.
Technical Context
This device integrates two platinum-doped FRED Pt® diodes in a planar common-cathode configuration, enabling shared cathode routing and reduced layout parasitics in dual-output or interleaved converter topologies. Its hyperfast trr (22–35 ns across 25–125 °C) and low stored charge minimize switching losses in hard-switched 100–500 kHz power stages.
The SMPD package provides low thermal resistance (RthJM typ. 1.8 °C/W), supports 260 °C lead-free reflow per J-STD-020 MSL Level 1, and delivers ruggedness via halogen-free, RoHS-compliant construction with matte tin-plated terminals solderable per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - blocks up to 200 V repetitive reverse voltage without breakdown in output rectification or snubber circuits |
| IF(AV) per diode | 10 A - supports continuous 10 A DC forward current per anode under Tsolder pad = 152 °C thermal condition |
| VF @ 10 A, 150 °C | 0.77 V - enables low conduction loss in high-temp industrial or automotive power supplies |
| trr (typ.) | 25 ns - ensures minimal reverse recovery energy loss in high-frequency switching applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hyperfast dual common-cathode rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSKD20A02HM3 | Same SMPD package, identical 200 V/2×10 A rating, but trr = 35 ns (max) and Qrr = 40 nC (max) - higher recovery energy | Suitable for lower-frequency (<150 kHz) or less thermally constrained designs where softness is secondary | Select when cost sensitivity outweighs efficiency optimization at high switching frequencies |
| STTH20L02CG | TO-220AC package, 200 V/2×10 A, trr = 30 ns (typ.), no AEC-Q101 qualification, RthJC = 1.5 °C/W (vs. RthJM = 1.8 °C/W) | Requires through-hole mounting and heatsink; not suitable for automotive or high-density SMT layouts | Choose only if legacy TO-220 footprint must be retained and AEC-Q101 is not required |
Compared with VSKD20A02HM3 and STTH20L02CG, the VS-20CDH02HM3/I delivers superior high-frequency efficiency via lower Qrr and tighter trr distribution, while its SMPD package and AEC-Q101 status make it uniquely suited for space-constrained, automotive-grade, or thermally demanding SMT power designs.

FAQ
What is the maximum junction temperature rating for the VS-20CDH02HM3/I?
The VS-20CDH02HM3/I has a maximum junction temperature (TJ max.) of +175 °C, verified per Vishay Doc. #95821 Absolute Maximum Ratings table. This rating enables reliable operation in high-ambient environments such as enclosed telecom modules or engine-bay-adjacent automotive electronics, provided thermal design meets RthJM ≤ 2.4 °C/W and solder pad temperature remains ≤ 152 °C.
Is the VS-20CDH02HM3/I suitable for automotive applications?
Yes, the VS-20CDH02HM3/I is AEC-Q101 qualified and meets JESD201 Class 2 whisker test requirements, making it suitable for automotive power electronics including onboard chargers, DC/DC converters, and body control modules. Its SMPD package, 175 °C TJ rating, and soft recovery characteristics support robust operation under automotive thermal and transient stress conditions.
What does the 'H' in VS-20CDH02HM3/I indicate?
The first 'H' in VS-20CDH02HM3/I denotes hyperfast recovery performance (per Vishay's ordering nomenclature guide in Doc. #95821), while the second 'H' confirms AEC-Q101 qualification. The 'M3' suffix indicates halogen-free, RoHS-compliant, and lead (Pb)-free terminations. The '/I' denotes tape-and-reel packaging with 2000 units per reel.
How does the common-cathode configuration of the VS-20CDH02HM3/I benefit PCB layout?
The common-cathode configuration of the VS-20CDH02HM3/I consolidates both diode outputs into a single terminal (Pin 3), minimizing return-path inductance and simplifying routing in dual-output or interleaved SMPS designs. This reduces voltage spikes during recovery and improves EMI performance compared to discrete single-diode solutions requiring separate cathode traces.
What is the typical reverse recovery charge (Qrr) of the VS-20CDH02HM3/I at 25 °C?
The typical reverse recovery charge (Qrr) of the VS-20CDH02HM3/I is 25 nC at TJ = 25 °C, as specified in the Dynamic Recovery Characteristics table of Vishay Doc. #95821. At 125 °C, Qrr rises to 85 nC - a key parameter for calculating switching losses and selecting complementary MOSFETs or gate drivers in high-frequency topologies.
