Product details
Overview
V10KL45CHM3/I from Vishay General Semiconductor is a dual common-cathode Trench MOS Barrier Schottky (TMBS®) rectifier in FlatPAK 5×6 package, rated for 45 V reverse voltage and 10 A total average forward current (2 × 5 A), with ultra-low VF of 0.29 V at 5 A and 125 °C - optimized for high-efficiency DC/DC converters and polarity protection in automotive and industrial power supplies.
For engineers reviewing the V10KL45CHM3/I datasheet, V10KL45CHM3/I pinout, V10KL45CHM3/I application, or V10KL45CHM3/I equivalent, key selection criteria include its AEC-Q101 qualification, 150 °C max junction temperature, MSL Level 1 rating, 100 A IFSM surge capability, and low RθJM of 2.5 °C/W for thermal management in space-constrained layouts.
Technical Context
This dual-diode Schottky rectifier uses trench MOS barrier technology to achieve lower forward voltage and higher current density than planar Schottky devices. Its common-cathode configuration supports synchronous rectification and bidirectional freewheeling paths in buck or half-bridge topologies.
Designed for surface-mount operation on PCBs with recommended copper pad area, it delivers stable performance across -40 °C to +150 °C junction temperature range and meets JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1 reflow requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 45 V - maximum repetitive reverse blocking voltage per diode; defines safe operating limit in clamping or flyback applications |
| IF(AV) | 2 × 5 A - total average forward current capacity split across two diodes; enables compact dual-channel rectification without parallel devices |
| VF @ 5 A, 125 °C | 0.35 V - ultra-low forward drop ensures <1.75 W conduction loss per diode at full load, critical for thermally constrained designs |
| IFSM | 100 A - peak surge current rating supports robustness against inrush and transient overloads in power supply startup |
| TJ max | +150 °C - extended junction temperature rating allows operation in under-hood automotive or high-ambient industrial environments |
| RθJM | 2.5 °C/W - low junction-to-mount thermal resistance enables efficient heat transfer to heatsink or copper plane, reducing thermal derating |
| CJ @ 4 V | 1100 pF - typical junction capacitance impacts switching speed and EMI in high-frequency (>100 kHz) converter designs |
Pinout & Package
Package: FlatPAK 5 × 6 - surface-mount, leadless, double-sided cooling package with matte tin-plated terminals; meets UL 94 V-0, RoHS, and halogen-free requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | Anode 1 | Input terminal for first Schottky diode; connects to switching node or input rail in freewheeling or polarity protection |
| 3, 4 | Anode 2 | Input terminal for second Schottky diode; enables independent or interleaved channel control in dual-output converters |
| 5, 6, 7, 8 | Common Cathode | Shared output node for both diodes; must be routed to ground or return path with low-inductance, high-current copper pour |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V10KL45C-M3/I | Non-AEC-Q101 version; identical electrical specs but lacks automotive qualification testing and HM3 suffix marking | Suitable for commercial/industrial use only; not approved for under-hood or safety-critical automotive subsystems | Select V10KL45CHM3/I when AEC-Q101 compliance is required; otherwise V10KL45C-M3/I offers cost advantage |
| SS1040H-13 | Single-diode TO-277 package; 40 V VRRM, 10 A IF(AV), VF = 0.52 V @ 10 A - higher VF and no dual configuration | Lacks common-cathode integration; requires two devices and larger PCB area for dual-channel function | V10KL45CHM3/I saves 40 % board space and delivers 0.17 V lower VF at 5 A - preferred for space- and efficiency-critical designs |
Compared with V10KL45C-M3/I and SS1040H-13, the V10KL45CHM3/I uniquely combines AEC-Q101 qualification, dual common-cathode topology, and industry-leading 0.29 V VF at 125 °C - making it the optimal choice for thermally demanding, automotive-grade, or high-density dual-output power conversion.

FAQ
What is the maximum junction temperature rating for the V10KL45CHM3/I?
The V10KL45CHM3/I has a maximum junction temperature (TJ max) of +150 °C, verified per Vishay's datasheet revision 18-Jun-2025. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial settings. Thermal design must ensure that actual TJ remains below this limit under worst-case power dissipation and ambient conditions - validated using RθJM = 2.5 °C/W and RθJA = 75 °C/W values from the datasheet.
Is the V10KL45CHM3/I pin-compatible with the V10KL45C-M3/I?
Yes, the V10KL45CHM3/I and V10KL45C-M3/I share identical FlatPAK 5 × 6 package dimensions, pinout, and terminal assignments - both feature pins 1–2 (Anode 1), 3–4 (Anode 2), and 5–8 (Common Cathode). The only differences are AEC-Q101 qualification and HM3 suffix marking on V10KL45CHM3/I; no PCB layout change is needed when upgrading between them.
Does the V10KL45CHM3/I support lead-free reflow soldering?
Yes, the V10KL45CHM3/I is rated for MSL Level 1 per J-STD-020 and withstands lead-free reflow peak temperatures up to 260 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD22-B102 solderability standards, and it passes JESD201 Class 2 whisker testing - eliminating pre-baking requirements and ensuring robust solder joint formation in high-volume SMT assembly.
What is the forward voltage drop of the V10KL45CHM3/I at 5 A and 125 °C?
The V10KL45CHM3/I exhibits a maximum forward voltage drop (VF) of 0.35 V at 5 A and 125 °C, as specified in the Vishay datasheet Document Number 87476. This ultra-low VF value is enabled by trench MOS barrier technology and directly contributes to reduced conduction losses - delivering 1.75 W per diode at full load instead of >2.6 W with conventional Schottky alternatives.
How does the common-cathode configuration of the V10KL45CHM3/I benefit power converter design?
The common-cathode configuration of the V10KL45CHM3/I allows two independent anodes (pins 1–2 and 3–4) to share a single low-inductance cathode return path (pins 5–8). This simplifies PCB layout for dual-output or interleaved converters, reduces parasitic inductance in high-di/dt paths, and enables efficient thermal coupling to a unified copper pour - improving both electrical performance and thermal management versus discrete single-diode solutions.
