Diodes Incorporated DXTP19020DP5-13

Overview

DXTP19020DP5 from Diodes Incorporated is a 20V PNP low-saturation transistor in PowerDI5 package, designed for high-current load switching and battery charging circuits. It delivers IC = –8A continuous, V_CEO = –20V, V_CE(sat) = –47mV at IC = –1A/IB = –100mA, and operates across –55°C to +150°C - enabling compact, thermally efficient automotive and industrial power management.

For engineers reviewing the DXTP19020DP5 datasheet, DXTP19020DP5 pinout, DXTP19020DP5 application, or DXTP19020DP5 equivalent, key selection criteria include its ultra-low saturation voltage under high current, 1.3W power rating on standard FR-4 PCB, AEC-Q101 readiness, and compatibility with space-constrained load disconnect topologies.

Technical Context

This PNP bipolar junction transistor uses epitaxial base construction to achieve high DC current gain (h_FE = 300 min at IC = –100mA) and fast switching performance (t_d = 23ns, t_f = 49.6ns). Its low R_θJA of 41.7°C/W (with optimized 0.42 in² collector pad) supports sustained 8A conduction without external heatsinking in ambient-limited environments.

The device integrates reverse-blocking capability (V_ECO = –4V, V_EBO = –7V) and exhibits stable gain across temperature (–55°C to +150°C), making it suitable for bidirectional control paths in battery protection ICs and smart load switches where emitter-follower configuration and low V_BE(sat) (–1.05V at –8A) reduce drive loss.

FAQ

What is the maximum continuous collector current for DXTP19020DP5 at 100°C ambient?

At T_A = 100°C with the recommended 0.42 in² copper pad, DXTP19020DP5 supports up to –5.2A continuous collector current. This is derived from its 3W power rating and R_θJA = 41.7°C/W, ensuring junction temperature remains below 150°C. Derating curves in Figure 2 of DS32012 confirm this value.

Can DXTP19020DP5 replace an NPN transistor in a high-side switch configuration?

No - DXTP19020DP5 is a PNP transistor and functions as a high-side switch when its emitter connects to the positive rail and collector to the load. Replacing an NPN would require inverting the control logic and verifying base drive polarity; it is not a drop-in substitute for NPN devices like MMBT4401.

Is DXTP19020DP5 qualified to AEC-Q101, and what evidence supports this claim?

Yes - Diodes Incorporated explicitly states that DXTP19020DP5 is "for automotive applications requiring specific change control (i.e., parts qualified to AEC-Q101…)" in the datasheet's Features section. Full AEC-Q101 test reports are available upon request through Diodes' automotive support team and referenced in their AEC-Q101 product definitions page.

What is the recommended PCB pad layout for optimal thermal performance?

Diodes specifies a minimum 0.42 in² (271 mm²) copper area connected to the collector pad using multiple thermal vias (≥6 × 0.3mm diameter) to inner ground/power planes. The exact dimensions and via pattern are detailed in the "Suggested Pad Layout" section of the PowerDI5 package outline document (PN: AP02010) on diodes.com/package-outlines.html.
