Diodes Incorporated ZXTP19060CFFTA

Overview

ZXTP19060CFF from Diodes Incorporated is a 60V PNP medium-power transistor optimized for high-side switching in motor drive and load disconnect applications, featuring -4A continuous collector current, < -75mV V_CE(sat) at -1A, 160 minimum h_FE at -1A, and 1.5W power dissipation in SOT23F package.

For engineers reviewing the ZXTP19060CFF datasheet, ZXTP19060CFF pinout, ZXTP19060CFF application, or ZXTP19060CFF equivalent, key selection criteria include verified AEC-Q101 qualification, low R_CE(sat) of 45mΩ, thermal resistance as low as 60°C/W on 50mm×50mm 2oz copper, and complementary pairing with ZXTN19060CFF for H-bridge designs.

Technical Context

This PNP bipolar junction transistor operates in linear and saturated switching modes, with BV_CEO = -60V and V_ECO = -7V enabling robust reverse-blocking capability in high-side configurations. Its h_FE is fully characterized from -100mA to -4A, supporting stable current gain across wide load ranges.

The device uses a thermally enhanced SOT23F package with exposed collector pad, achieving R_θJL = 43.77°C/W and R_θJA down to 60°C/W under optimal PCB layout-critical for power-dense automotive and industrial control modules requiring sustained -4A conduction without forced cooling.

Key Specifications

Pinout & Package

The ZXTP19060CFF is housed in a surface-mount SOT23F package with exposed collector pad for enhanced thermal performance. Dimensions conform to Diodes Inc. outline SOT23F (D = 2.90mm, E = 2.40mm, E1 = 1.65mm, L = 0.50mm), compatible with standard SOT23 footprints but offering lower profile and higher power handling.

FAQ

What is the maximum safe operating temperature for ZXTP19060CFF?

The device has an operating junction temperature range of -55°C to +150°C. Under continuous DC operation with 50mm×50mm 2oz copper, its maximum ambient temperature before reaching 150°C junction is +90°C at 1.5W dissipation. Derating curves in DS33734 Rev. 3-2 specify linear reduction beyond +25°C ambient.

Does ZXTP19060CFF require a base resistor when driven by a 3.3V microcontroller?

Yes-a series base resistor is mandatory to limit I_B within the -1A absolute maximum. For saturation at -1A I_C, h_FE ≥160 requires ≥-6.25mA I_B; with 3.3V GPIO and V_BE(sat) ≈ -0.95V, a 390Ω resistor sets I_B ≈ -6.2mA, ensuring reliable turn-on without overstress.

Can ZXTP19060CFF be used in parallel for higher current capacity?

No-BJTs exhibit negative temperature coefficient of V_BE, causing current hogging if paralleled without individual emitter resistors. The datasheet does not characterize matching or recommend paralleling; for >4A, use a single higher-rated device or MOSFET-based solution.

Is the SOT23F package lead-free and RoHS compliant?

Yes-ZXTP19060CFF is fully RoHS 2 compliant (2011/65/EU), lead-free, halogen-free, and antimony-free per Diodes Inc.'s "Green" definition (<900ppm Br, <900ppm Cl, <1000ppm Sb). Matte tin-plated leads meet MIL-STD-202 solderability requirements.
