Diodes Incorporated ZXTP2012GTA

Overview

ZXTP2012GTA from Diodes Incorporated is a 60V PNP medium-power low-saturation bipolar junction transistor in SOT223 package, rated for −5.5A continuous collector current and −70mV max V_CE(SAT) at −1A. It delivers 39mΩ equivalent on-resistance at −5A, supports AEC-Q101 qualification, and is used in DC-DC converters and MOSFET gate drivers where high-current switching with minimal conduction loss is required.

For engineers reviewing the ZXTP2012GTA datasheet, ZXTP2012GTA pinout, ZXTP2012GTA application, or ZXTP2012GTA equivalent, key selection criteria include verified −60V V_CEO, guaranteed h_FE ≥100 at −10A, thermal resistance R_θJA = 42°C/W (on 52mm × 52mm 2oz Cu), pulsed switching times (t_ON = 39ns, t_OFF = 370ns), and RoHS-compliant green packaging.

Technical Context

This PNP transistor operates as a medium-power switch with robust avalanche-rated breakdown (−100V V_CBO, −60V V_CEO) and specified gain up to −10A, enabling stable current amplification in high-load linear and saturated switching modes. Its low V_CE(SAT) (−70mV max @ −1A) and low R_SAT (39mΩ @ −5A) reduce power dissipation in high-current paths.

The device features AEC-Q101 qualification, JEDEC Class 3A HBM ESD rating (4kV), and thermal performance validated under two PCB mounting conditions: R_θJA = 42°C/W (52mm × 52mm 2oz Cu) and 78°C/W (25mm × 25mm 1oz Cu), supporting design-in for automotive and industrial power stages.

FAQ

What is the maximum continuous power dissipation for ZXTP2012GTA at 25°C ambient?

The ZXTP2012GTA has a maximum power dissipation (P_D) of 3.0W at T_A = +25°C when mounted on a 52mm × 52mm 2oz copper PCB. Derating begins at 24mW/°C above 25°C, reaching zero dissipation at approximately 152°C ambient. This value assumes still-air conditions and proper thermal pad layout per AP02001 guidelines.

Does ZXTP2012GTA support operation at elevated junction temperatures?

Yes-ZXTP2012GTA is rated for junction temperatures from −55°C to +150°C. Its h_FE, V_CE(SAT), and leakage parameters are characterized across this full range, with typical h_FE retention of ≥25 at −10A and +100°C, and I_CBO remaining below −0.5µA at +100°C with V_CB = −80V.

Can ZXTP2012GTA replace a standard PNP Darlington pair in gate drive circuits?

No-it is not a Darlington device and lacks internal gain boosting. With h_FE = 100–300 (not 1000+), it requires higher base drive current than Darlingtons. However, its faster switching (t_ON = 39ns, t_OFF = 370ns) and lower V_CE(SAT) make it preferable where speed and efficiency outweigh drive simplicity.

Is the collector tab electrically isolated from other pins?

No-the collector tab is internally bonded to Pin 3 (collector) and is not insulated. It must be connected to the same net as Pin 3 and soldered directly to a thermal pad on the PCB. Any attempt to isolate the tab will compromise both electrical function and thermal performance, violating the device's qualified mounting configuration.
