Product details

Overview

SK86CHR7G from Taiwan Semiconductor is an 8A, 60V Schottky barrier surface-mount rectifier in DO-214AB (SMC) package, featuring VF = 0.75V at 8A/25°C, IR ≤ 10mA at 100°C, and IFSM = 150A (8.3ms), used in high-efficiency SMPS secondary-side rectification.

For engineers reviewing the SK86CHR7G datasheet, SK86CHR7G pinout, SK86CHR7G application, or SK86CHR7G equivalent, key selection criteria include forward voltage drop at full load, thermal resistance (R_θJA = 20°C/W), reverse leakage at elevated temperature, surge current rating, and DO-214AB mechanical compatibility with automated SMT lines.

Technical Context

This Schottky rectifier employs a single-die construction optimized for low conduction loss in DC-DC output stages. Its 60V V_RRM rating targets mid-voltage secondary-side applications where efficiency and thermal management are critical, and its 10,000 V/µs dV/dt rating supports fast-switching topologies.

The device operates across –55°C to +150°C junction range, with moisture sensitivity level 1 (J-STD-020) and matte tin-plated leads compliant with J-STD-002 solderability. Guard ring structure provides overvoltage protection without compromising forward performance.

Key Specifications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-8EWH06FN-M3/45	Same DO-214AB package, 8A/60V, VF = 0.71V @ 8A but IR = 15mA @ 100°C (higher leakage)	Better efficiency at room temp; less suitable for high-ambient sealed LED drivers	Prefer when board-level thermal margin is ample and leakage sensitivity is low
ON Semiconductor SB860-E3/45	DO-214AB, 8A/60V, VF = 0.77V @ 8A, IR = 8mA @ 100°C, R_θJA = 22°C/W	Slightly higher VF and thermal resistance; tighter IR spec ideal for high-temp reliability	Prefer when long-term stability at >100°C junction is prioritized over minimal conduction loss

Compared with VS-8EWH06FN-M3/45 and SB860-E3/45, SK86CHR7G delivers balanced performance: lower IR than Vishay at high temperature and lower VF than ON Semi, while maintaining identical package fit and 20°C/W thermal resistance for predictable thermal design.

FAQ

What is the maximum junction temperature rating for SK86CHR7G?

The SK86CHR7G has a maximum junction temperature (T_J) rating of +150°C, allowing continuous operation in high-ambient industrial environments such as enclosed LED drivers or DIN-rail power supplies. This rating is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version L2102), and applies across the full operating current range up to 8A.

Does SK86CHR7G have a guard ring structure, and what benefit does it provide?

Yes, SK86CHR7G incorporates a guard ring structure explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. This design enhances ruggedness against transient overvoltage events-such as line surges or inductive kickback-without degrading forward voltage or reverse leakage performance, improving reliability in unregulated or noisy power systems.

Is SK86CHR7G suitable for lead-free reflow soldering processes?

Yes, SK86CHR7G is qualified for lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and its moisture sensitivity level is rated at Level 1 per J-STD-020-meaning it can be stored indefinitely at ≤30°C/60% RH and placed directly into reflow without pre-baking, simplifying SMT line integration.

What is the reverse leakage current specification for SK86CHR7G at elevated temperature?

At rated reverse voltage and junction temperature of 100°C, SK86CHR7G exhibits a maximum reverse leakage current (I_R) of 10 mA, as specified in the Electrical Specifications table. This value is critical for high-temperature applications like sealed outdoor LED drivers, where excessive leakage could cause thermal runaway or output regulation drift.

How does the forward voltage of SK86CHR7G compare to SK85C and SK810C in the same family?

Within the SK8xC family, SK86CHR7G shares the same forward voltage specification as SK85C: 0.75 V typical at 8A and 25°C. In contrast, SK82C–SK84C specify 0.55 V, while SK810C specifies 0.90 V. This tiered VF reflects optimized die design per voltage rating-SK86CHR7G balances low loss and 60V blocking capability for mid-range SMPS applications.
