Diodes Incorporated DXT2907A-13

Overview

DXT2907A-13 from Diodes Incorporated is a 60V PNP bipolar junction transistor in SOT89 package, rated for -600mA continuous collector current and -60V V_CEO, with h_FE = 100–300 at I_C = -150mA, used in medium-power switching and linear amplification circuits in automotive body control modules and industrial power supplies.

For engineers reviewing the DXT2907A-13 datasheet, DXT2907A-13 pinout, DXT2907A-13 application, or DXT2907A-13 equivalent, key selection criteria include guaranteed V_CEO ≥ -60V, low V_CE(SAT) ≤ -400mV at I_C = -150mA/IB = -15mA, AEC-Q101 qualification, and SOT89 thermal performance with R_θJA = 104°C/W on 25mm² copper.

Technical Context

This PNP transistor operates in common-emitter configuration with DC current gain (h_FE) specified across five collector current levels from -100µA to -500mA, supporting both switching and analog amplification. Its complementary NPN counterpart is DXT2222A, enabling push-pull stage design.

Switching performance is characterized by t_ON ≤ 45ns, t_OFF ≤ 100ns, and f_T = 200MHz at I_C = -50mA/V_CE = -20V, confirming suitability for medium-speed digital logic interfacing and PWM-driven loads up to ~100kHz.

FAQ

What is the maximum allowable junction temperature for DXT2907A-13?

The device is rated for TJ = -55°C to +150°C. At TA = +70°C and PD = 0.75W with RθJA = 104°C/W, calculated TJ = 147°C - within spec. Derating is required above +70°C ambient per Figure 1 in the datasheet.

Can DXT2907A-13 replace a 2N2907 in existing designs?

Yes, with verification of layout compatibility: both are PNP transistors with matching VCEO (-60V), hFE range, and pinout (E-B-C). However, DXT2907A-13 uses SOT89 instead of TO-92, requiring PCB footprint change and thermal pad implementation.

Is the exposed collector pad electrically isolated from other pins?

No - the exposed collector pad is internally connected to Pin 3 (Collector). It must be routed to the same net as Pin 3 and tied to a thermal copper pour; floating or grounded connection will cause malfunction or damage.

Does DXT2907A-13 support pulse-width modulation (PWM) switching?

Yes - with tON ≤ 45ns and tOFF ≤ 100ns, it supports PWM frequencies up to ~1MHz for low-duty-cycle signals. For 10–100kHz motor/LED control, it delivers efficient switching with minimal overlap loss when paired with appropriate base drive.
