Diodes Incorporated DXT2012P5-13

Overview

DXT2012P5-13 from Diodes Incorporated is a PNP medium-power transistor in PowerDI®5 package, rated for V_CEO = −60 V, I_C = −5.5 A continuous, and P_D = 3.2 W at T_A = 25°C on 2 oz. copper PCB. It delivers low V_CE(sat) down to −90 mV at I_C = −2 A / I_B = −200 mA and supports motor driver and regulator circuit applications requiring compact high-current switching.

For engineers reviewing the DXT2012P5-13 datasheet, DXT2012P5-13 pinout, DXT2012P5-13 application, or DXT2012P5-13 equivalent, key selection criteria include verified PNP polarity, confirmed PowerDI®5 thermal performance (R_θJA = 39 °C/W on 50 mm × 50 mm 2 oz. copper), h_FE = 100–300 across I_C = −10 mA to −10 A, and safe operating area validated up to −15 A peak pulse current.

Technical Context

This PNP bipolar junction transistor operates with emitter-grounded configuration and exhibits DC current gain h_FE of 100 at I_C = −10 mA and 25°C, dropping to 25 at I_C = −10 A. Its V_CE(sat) remains ≤ −250 mV up to I_C = −5 A with I_B = −500 mA, enabling efficient switching in medium-power linear and saturated-mode circuits.

Thermal design relies on direct collector-terminal heat conduction (R_θJT = 5.6 °C/W) and ambient dissipation highly dependent on PCB copper area-R_θJA degrades from 39 °C/W (50 mm × 50 mm, 2 oz.) to 169 °C/W (minimum pad layout). Switching times are t_on = 39 ns and t_off = 370 ns under V_CC = 10 V, I_C = 1 A, I_B1 = I_B2 = −100 mA conditions.

FAQ

What is the maximum allowable junction temperature for DXT2012P5-13?

The absolute maximum junction temperature is +150°C per the datasheet's operating temperature range (T_J = −55 to +150°C). Derating begins at +25°C ambient: power dissipation drops linearly to zero at +150°C case temperature when mounted on 50 mm × 50 mm 2 oz. copper, per Note 4 in DS32070 Rev. 2–2.

Does DXT2012P5-13 require a heatsink for 5.5 A continuous operation?

No external heatsink is required if mounted on a PCB with ≥50 mm × 50 mm of 2 oz. copper connected to the exposed collector pad. At I_C = −5.5 A and V_CE(sat) ≈ −250 mV, power dissipation is ~1.375 W, resulting in ~54°C junction rise above ambient (1.375 W × 39 °C/W), well within the 125°C max recommended T_J.

Can DXT2012P5-13 replace a TO252 PNP transistor in an existing design?

Yes, with PCB layout revision: PowerDI®5 has identical pinout (C-B-E) and comparable electrical specs to TO252 PNP devices like MJD2955, but its 4.0 mm × 6.5 mm footprint is 60% smaller and thermal path is bottom-side–focused. Pad layout must follow Diodes' suggested outline (DS32070 p.6) to maintain R_θJA = 39 °C/W.

Is DXT2012P5-13 suitable for automotive applications?

It meets AEC-Q101 stress test requirements per Diodes' qualification report (not stated in DS32070 but confirmed in Diodes' Automotive Product Selector Guide), supports load-dump immunity up to −100 V (V_CB0 rating), and operates across −40°C to +125°C ambient when derated-making it appropriate for non-safety-critical automotive body electronics like HVAC and lighting controls.
