Diodes Incorporated DXTN3C60PS-13

Overview

DXTN3C60PS from Diodes Incorporated is a 60V, 3A NPN bipolar junction transistor in PowerDI5060-8 package, optimized for low-saturation operation in medium-power linear and switching applications. It delivers R_CE(SAT) ≤ 90 mΩ at I_C = 3 A, supports continuous operation up to +175°C, and features V_CEO = 60 V and h_FE = 100–400 (I_C = 0.5–3 A), enabling robust load switching in automotive cabin modules.

For engineers reviewing the DXTN3C60PS datasheet, DXTN3C60PS pinout, DXTN3C60PS application, or DXTN3C60PS equivalent, key selection criteria include its 175°C rated junction temperature, 2.5 W power dissipation capability on standard PCB layout, low V_CE(SAT) performance under high-current drive, and AEC-Q101 qualification path via companion part DXTN3C60PSQ.

Technical Context

This NPN transistor operates in active, saturation, and cutoff regions with verified DC current gain (h_FE) ranging from 50–400 across 0.1–3 A collector current and 2 V V_CE. Its thermal resistance R_θJC = 2°C/W enables efficient heat transfer from junction to case under high-duty-cycle linear-mode regulation.

The device exhibits f_T = 140 MHz at V_CE = 10 V and I_C = 100 mA, supporting fast switching in backlight dimming circuits, while ESD ratings of 8 kV HBM and 400 V MM confirm suitability for assembly environments without additional protection circuitry.

FAQ

What is the maximum allowable base current for continuous operation?

The datasheet specifies I_B = 500 mA as the absolute maximum rating, but for reliable continuous operation at full I_C = 3 A, the recommended base drive is 300 mA (I_C/I_B = 10). Exceeding this without thermal derating risks localized heating at the base-emitter junction and accelerated degradation.

Can DXTN3C60PS be used in avalanche mode?

No-DXTN3C60PS is not rated or characterized for avalanche energy handling. Its BV_CBO and BV_CEO are specified as minimum values under DC conditions only, and the device lacks published single-pulse avalanche energy (E_AS) or ruggedness data. Use only within safe operating area (SOA) limits defined in the datasheet.

Is the PowerDI5060-8 package lead-free and RoHS compliant?

Yes-DXTN3C60PS uses matte tin annealed over copper leadframe, conforms to EU RoHS 2015/863/EU, and carries Diodes' "Green" certification: <900 ppm bromine/chlorine, <1000 ppm antimony, and zero halogenated flame retardants per JEDEC J-STD-020 Level 1 moisture sensitivity.

How does thermal resistance change with PCB copper area?

R_θJA = 60°C/W is measured on 25 mm × 25 mm 2 oz copper; reducing copper area increases R_θJA nonlinearly-e.g., halving the pad area raises R_θJA to ~95°C/W. The exposed collector pad must be connected to ≥200 mm² of inner-layer copper via ≥4 thermal vias (0.3 mm diameter) for optimal junction-to-PCB thermal transfer.
