Product details

Overview

V20D202C-M3/I from Vishay General Semiconductor is a dual high-voltage Trench MOS Barrier Schottky (TMBS®) rectifier in SMPD (TO-263AC) package, configured as common cathode, rated for 200 V repetitive peak reverse voltage, 2 × 10 A average forward current per diode, and 0.68 V forward voltage at 10 A and 125 °C - used in high-frequency DC/DC converters and reverse battery protection circuits.

For engineers reviewing the V20D202C-M3/I datasheet, V20D202C-M3/I pinout, V20D202C-M3/I application, or V20D202C-M3/I equivalent, key selection criteria include its dual common-cathode topology, 175 °C max junction temperature, MSL Level 1 rating, AEC-Q101 qualified variant availability, and low-profile 1.7 mm height for space-constrained power stages.

Technical Context

This device implements second-generation trench MOS Schottky technology to achieve low VF and high dV/dt immunity (10,000 V/μs), enabling efficient operation in fast-switching topologies. Its common-cathode dual-die construction shares a single thermal pad, supporting symmetrical current sharing and simplified PCB layout for OR-ing and freewheeling functions.

The SMPD (TO-263AC) package provides low thermal resistance (RθJC = 2.8 °C/W per diode; RθJA = 58 °C/W), matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102, and meets UL 94 V-0 flammability requirements - optimized for automated SMT placement and reflow up to 260 °C peak.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	200 V - supports input rails up to 160 V DC with margin for transient spikes in industrial and automotive power supplies
IF(AV) per diode	10 A - enables continuous 10 A conduction per anode in dual-channel configurations without derating below 125 °C case temp
VF @ 10 A, 125 °C	0.68 V - reduces conduction loss to ≤6.8 W per diode, critical for >95 % efficiency in high-density 48 V–12 V DC/DC stages
IFSM	150 A - withstands short-duration inrush and fault currents typical in hot-swap and load-dump scenarios
TJ max	175 °C - allows operation in under-hood automotive environments and sealed industrial enclosures without active cooling
RθJC	2.8 °C/W per diode - enables direct heatsink coupling via exposed cathode pad for thermal management in high-power density designs
MSL Level	Level 1 (J-STD-020) - permits unlimited floor life and standard reflow profiles without baking preconditioning

Pinout & Package

Pin 3	Anode 2	Input terminal for second diode channel; enables independent control or redundancy in dual-rail systems

Key Features

Feature	Design Value
Trench MOS Schottky Gen 2	Enables 0.68 V VF at 10 A/125 °C - 15–20 % lower conduction loss vs. planar Schottky equivalents
Common-cathode dual configuration	Reduces component count and layout area by integrating two matched diodes in single SMPD footprint
1.7 mm profile	Supports ultra-low-profile power modules and stacked PCB assemblies where Z-height is constrained to <2.0 mm

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
V20D202CHM3_B/I	AEC-Q101 qualified; identical electrical specs and package; B revision adds enhanced process control for automotive lot traceability	Required for automotive OEM designs needing PPAP documentation and zero-defect reliability validation	Select V20D202CHM3_B/I when qualifying for ASIL-B systems or Tier-1 automotive supply chains
STPS20H100CG-TR	100 V VRRM (vs. 200 V); TO-263AB package; 20 A total IF(AV); VF = 0.75 V @ 10 A, 150 °C	Suitable only for ≤48 V systems; lacks 200 V margin needed for 400 V EV auxiliary supplies or industrial 380 V AC-derived rails	Choose STPS20H100CG-TR only for cost-sensitive 12–48 V non-automotive applications where 100 V rating is sufficient

Compared with V20D202C-M3/I, the HM3_B/I variant adds automotive qualification without electrical trade-offs, while STPS20H100CG-TR offers lower cost but sacrifices 100 V reverse voltage headroom and automotive compliance - making V20D202C-M3/I optimal for 200 V industrial and extended-temperature DC/DC designs.

FAQ

What is the maximum junction temperature rating for the V20D202C-M3/I?

The V20D202C-M3/I has a maximum junction temperature (TJ max) of +175 °C, verified per Vishay Document Number 87747. This rating enables reliable operation in under-hood automotive environments and sealed industrial enclosures. The device maintains specified VF and IR performance up to this limit, provided thermal design respects RθJC = 2.8 °C/W per diode and adequate PCB copper area is used for heat dissipation. Derating curves in Figure 1 confirm 10 A per diode capability at 125 °C case temperature.

Is the V20D202C-M3/I pin-compatible with other SMPD-packaged dual Schottky rectifiers?

The V20D202C-M3/I uses the standard SMPD (TO-263AC) outline with 3-terminal common-cathode pinout (Anode–Cathode–Anode), matching industry-standard land patterns for TO-263AC. However, pin compatibility does not guarantee functional equivalence - V20D202C-M3/I's 200 V VRRM and 0.68 V VF at 10 A/125 °C differ from lower-voltage variants like STPS20H100CG-TR. Always verify voltage rating, thermal resistance, and polarity marking before substitution.

Does the V20D202C-M3/I meet automotive qualification standards?

The base V20D202C-M3/I is not AEC-Q101 qualified; however, the automotive-grade variant V20D202CHM3_B/I carries full AEC-Q101 qualification per Vishay's ordering matrix. Both share identical electrical specs and SMPD package, but HM3_B/I includes enhanced process controls, lot traceability, and PPAP documentation required for automotive OEM acceptance. For non-automotive industrial use, V20D202C-M3/I remains fully compliant with RoHS and halogen-free standards.

What is the thermal resistance from junction to case for the V20D202C-M3/I?

The V20D202C-M3/I has a typical junction-to-case thermal resistance (RθJC) of 2.8 °C/W per diode, as specified in the "Thermal Characteristics" table of Vishay Document Number 87747. This value applies when heat is extracted solely through the exposed cathode pad (Pin 2). For system-level thermal modeling, note that RθJA is 58 °C/W under free-air conditions, but improves significantly with ≥2 cm² of 70 μm copper on FR4 PCB - see Figure 7 for copper-area dependency curves.

How does the V20D202C-M3/I perform at elevated temperatures?

The V20D202C-M3/I maintains low forward voltage - 0.68 V at 10 A and 125 °C - and exhibits controlled reverse leakage: ≤10 mA at 200 V and 125 °C. Its 175 °C TJ max and robust dV/dt rating (10,000 V/μs) ensure stable operation in thermally demanding environments such as motor drive heatsinks or enclosed power supplies. Derating curves (Fig. 1) show usable current remains above 8 A per diode even at 150 °C case temperature, supporting high-temperature industrial deployments.
