Nexperia USA Inc. PDTA143ZM,315

Overview

PDTA143ZM from Nexperia is a PNP resistor-equipped transistor (RET) in SOT883 (DFN1006-3) package, rated for −50 V V_CEO, −100 mA I_O, with integrated R₁ = 4.7 kΩ and R₂/R₁ = 10, used as a digital switch for automotive IC inputs and load control.

For engineers reviewing the PDTA143ZM datasheet, PDTA143ZM pinout, PDTA143ZM application, or PDTA143ZM equivalent, this part serves as an AEC-Q101-qualified, space-constrained PNP switching solution with built-in biasing to replace discrete base-resistor designs in cost-sensitive digital logic interfaces.

Technical Context

This RET integrates a PNP bipolar transistor with two precision on-die resistors: R₁ (4.7 kΩ) connects input to base, and R₂ (47 kΩ) connects base to emitter, enabling single-pin drive and guaranteed saturation at I_C = −5 mA with I_B = −0.25 mA.

It operates within −65 °C to +150 °C ambient range, delivers h_FE ≥ 100 at V_CE = −5 V / I_C = −10 mA, and exhibits V_CE(sat) ≤ −100 mV under standard switching conditions-optimized for low-power digital signal routing in automotive ECUs and industrial sensors.

FAQ

What is the maximum operating temperature for PDTA143ZM?

The junction temperature (T_j) must not exceed +150 °C, and ambient temperature (T_amb) is rated from −65 °C to +150 °C. Derating begins at T_amb > 25 °C per the power derating curve in Figure 1, where P_tot drops linearly to zero at 150 °C on FR4 PCB.

Can PDTA143ZM be used with 3.3 V logic inputs?

Yes. VI(on) is −0.9 V (typical) at I_C = −5 mA, meaning a 3.3 V logic HIGH applied to pin 1 (via level translator or direct connection in open-collector configuration) fully saturates the device. VI(off) is −0.6 V (typical), ensuring clean turn-off with 0 V input.

Is thermal resistance specified for SOT883 mounting?

Yes. R_th(j-a) is 500 K/W when mounted on an FR4 PCB with 70 µm copper strip line and standard footprint (per Table 6). This value assumes reflow soldering only-hand-soldering or non-standard land patterns will increase thermal resistance.

How does the R₂/R₁ ratio affect switching behavior?

The fixed R₂/R₁ = 10 ratio ensures base-emitter feedback stabilizes bias current across temperature, preventing thermal runaway. It guarantees I_B/I_C ≈ 0.05 at saturation, delivering consistent V_CE(sat) ≤ −100 mV without external trimming.
