Nexperia USA Inc. PDTB113ZQAZ

Overview

PDTB113ZQAZ from Nexperia is a PNP resistor-equipped transistor (RET) designed for digital switching applications, featuring integrated 1 kΩ and 10 kΩ bias resistors, −50 V collector-emitter voltage rating, −500 mA output current capability, and AEC-Q101 qualification for automotive use. It operates as a single-stage logic-level switch in low-voltage control circuits driving IC inputs or small loads.

For engineers reviewing the PDTB113ZQAZ datasheet, PDTB113ZQAZ pinout, PDTB113ZQAZ application, or PDTB113ZQAZ equivalent, this device serves as a space-optimized, AOI-compatible alternative to discrete BJT + resistor solutions in high-volume digital interface and load-switching designs requiring stable gain and predictable turn-on/off thresholds.

Technical Context

This RET integrates a PNP bipolar transistor with two precision on-die resistors (R1 = 1 kΩ, R2 = 10 kΩ) configured as a base-bias network, eliminating external components while maintaining ±10% resistor ratio tolerance. Its DFN1010D-3 (SOT1215) package enables ultra-thin mounting (0.37 mm height) and supports automated optical inspection of solder joints.

The device delivers DC current gain (h_FE) ≥70 at −50 mA collector current and −5 V V_CE, with V_CE(sat) ≤ −100 mV at I_C = −50 mA / I_B = −2.5 mA, enabling low-loss switching in 3.3 V and 5 V logic-controlled paths. Off-state input voltage (V_I(off)) ranges from −0.3 V to −1 V, ensuring robust noise immunity in noisy digital environments.

FAQ

What is the maximum continuous power dissipation for PDTB113ZQAZ on a standard FR4 PCB?

On a standard FR4 PCB with single-sided copper and tin-plated traces (footprint per datasheet), PDTB113ZQAZ has a maximum total power dissipation (P_tot) of 325 mW at T_amb = 25 °C. Derating begins above 25 °C at 2.6 mW/°C, reaching zero dissipation at approximately 148 °C ambient. Thermal resistance from junction to ambient (R_th(j-a)) is 385 K/W under these conditions.

Can PDTB113ZQAZ be used as a direct replacement for BC807-40 in existing designs?

Yes, PDTB113ZQAZ can replace BC807-40 in most digital switching applications, provided the circuit uses the standard 1 kΩ/10 kΩ base bias configuration. It matches the same −50 V V_CEO, −500 mA I_O, and SOT23-compatible pinout functionally-but in a smaller DFN1010D-3 package. Layout redesign is required due to different footprint and dual-collector terminals.

What is the significance of the "QAZ" suffix in PDTB113ZQAZ?

The "QAZ" suffix denotes the specific packaging and marking variant: DFN1010D-3 (SOT1215) package with tape-and-reel delivery, RoHS-compliant finish, and binary top-side marking code "01 11 10". It distinguishes this version from other variants like "QA" (same package, different reel quantity) and confirms full AEC-Q101 qualification per datasheet Rev. 1.

How does the dual-collector terminal (pins 3 and 4) affect PCB layout and thermal performance?

Pins 3 and 4 are internally shorted to the same collector node, allowing parallel copper pours to enhance current handling and reduce thermal resistance. Layout best practice is to connect both pads to a common thermal land (≥1 cm² recommended for 575 mW operation), improving heat transfer to the PCB and enabling higher sustained current in compact designs.
