Diodes Incorporated DXTP560BP5-13

Overview

DXTP560BP5-13 from Diodes Incorporated is a PNP silicon planar high-voltage transistor in POWERDI®5 package, rated for -500V V_CEO, -150mA continuous collector current, and 2.8W power dissipation at 25°C ambient on 50mm × 50mm 2oz copper PCB. It serves as a gate driver or startup switch in offline lighting and motor control circuits where high breakdown voltage and compact thermal profile are critical.

For engineers reviewing the DXTP560BP5-13 datasheet, DXTP560BP5-13 pinout, DXTP560BP5-13 application, or DXTP560BP5-13 equivalent, key selection criteria include verified -500V BV_CEO, R_θJA = 45°C/W under standard mounting, V_CE(sat) ≤ -500mV at I_C = -50mA/I_B = -10mA, h_FE ≥ 15 at I_C = -100mA, and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This PNP transistor employs a planar silicon structure optimized for high-voltage blocking and fast switching in offline power supplies. Its -500V V_CEO and -500V V_CBO ratings enable direct use in 400V DC bus applications without cascading, while the 110ns turn-on and 1500ns turn-off times support operation up to several hundred kHz in flyback startup circuits.

The POWERDI®5 package integrates an exposed collector pad for low R_θJL = 14°C/W and enables 2.8W steady-state dissipation when fully soldered to copper. Its 1.1mm profile and halogen-free, RoHS-compliant construction meet space-constrained and environmental requirements in industrial lighting and motor drive PCBs.

FAQ

What is the maximum allowable junction temperature for DXTP560BP5-13?

The absolute maximum junction temperature is +150°C, as specified in the Thermal Characteristics table. Operation above this limit risks permanent degradation of h_FE and increased leakage. Derating begins at +25°C ambient, with linear reduction of P_D by 22.4mW/°C when mounted on 50mm × 50mm 2oz copper.

Can DXTP560BP5-13 be used as a direct replacement for TO-252 (D-PAK) PNP transistors?

No-it is not a drop-in replacement due to different pinout (C-E-B vs. E-B-C), smaller footprint, and distinct thermal interface. The POWERDI®5 exposes the collector on the bottom, requiring full-solder pad attachment, whereas TO-252 uses a top-side tab. Layout redesign and thermal validation are mandatory.

Is the -500V rating applicable to both DC and pulsed conditions?

Yes-the -500V V_CEO and V_CBO ratings are DC maximums validated under steady-state conditions per JEDEC JESD22-A108. Pulse ratings exceed DC values only if duty cycle ≤2% and pulse width ≤300μs, as noted for switching parameter tests.

Does DXTP560BP5-13 require a base resistor, and what value is recommended?

Yes-a series base resistor is mandatory to limit I_B and prevent thermal runaway. For I_C = -50mA and h_FE ≥ 15, minimum I_B = -3.3mA is needed. With V_BE(sat) ≈ -0.9V and 5V drive, a 1.2kΩ resistor delivers ~3.4mA, ensuring saturation while maintaining margin against variation.
