STMicroelectronics STY130NF20D

Overview

STY130NF20D from STMicroelectronics is an N-channel enhancement-mode Power MOSFET in Max247 package, rated for 200 V V_DS, 0.012 Ω R_DS(on) (typ.), 130 A continuous drain current at T_C = 25 °C, and featuring an intrinsic fast-recovery body diode with 190 ns t_rr at 150 °C. It is engineered for high-efficiency hard-switching topologies in industrial motor drives and DC-DC converters.

For engineers reviewing the STY130NF20D datasheet, STY130NF20D pinout, STY130NF20D application, or STY130NF20D equivalent, key selection criteria include its 338 nC total gate charge, 25 V/ns dv/dt capability, 100% avalanche tested ruggedness, and thermal resistance of 0.28 °C/W (junction-to-case), critical for high-power switching reliability and thermal management.

Technical Context

This device employs ST's STripFET™ II process to minimize input capacitance (C_iss = 11100 pF) and gate charge, enabling fast switching with t_d(on) = 232 ns and t_f = 250 ns under standard test conditions. Its integrated fast-recovery body diode supports synchronous rectification and reduces external component count.

The MOSFET operates across –55 to 150 °C junction temperature range and delivers 800 mJ single-pulse avalanche energy at T_j = 25 °C. Its safe operating area (SOA) is defined up to 130 A and 200 V with pulse-width limitation governed by T_jmax.

Key Specifications

Pinout & Package

The STY130NF20D uses the Max247 package - a through-hole, isolated-tab power package with 3 terminals and internal source-connected tab for low-inductance, high-current PCB layout. Thermal pad is electrically connected to source.

FAQ

What is the maximum continuous drain current at 100 °C case temperature?

The STY130NF20D supports 82 A continuous drain current at T_C = 100 °C, as specified in Table 2 of the datasheet. This derating reflects thermal limitations of the Max247 package and must be applied when heatsink temperature exceeds 25 °C ambient. Designers should verify SOA compliance using Figure 2 for pulsed conditions.

Does the body diode require external snubbing in hard-switched bridge applications?

No external snubbing is required for typical hard-switched operation due to the device's 25 V/ns dv/dt immunity and 190 ns t_rr at 25 °C. However, at elevated junction temperatures (>125 °C), t_rr increases to 257 ns and Q_rr rises to 2.4 μC, so layout optimization and gate resistor tuning are recommended to manage recovery overshoot.

Is the Max247 package RoHS-compliant and lead-free?

Yes, the STY130NF20D is offered in ECOPACK®-compliant Max247 packaging, meeting RoHS Directive 2011/65/EU and REACH regulations. The device uses lead-free terminations and halogen-free molding compound, with full compliance documentation available on ST's official website under ECOPACK® grade definitions.

Can STY130NF20D replace older STY130NF20 in existing designs?

Yes - STY130NF20D is a direct replacement for STY130NF20, sharing identical pinout, electrical ratings, and package. Key improvements include enhanced avalanche ruggedness (100% tested), tighter R_DS(on) distribution, and updated thermal characterization per Rev 4 datasheet. No layout or driver changes are needed for drop-in substitution.
