Product details

Overview

2PB710AR,115 from Nexperia is a PNP general purpose bipolar junction transistor in SOT346 (SC-59) package, rated for −50 V V_CEO, −500 mA I_C, with DC current gain h_FE of 120–240 at −150 mA/−10 V, and f_T = 120 MHz - used in low-voltage switching and linear amplification circuits in consumer power management.

For engineers reviewing the 2PB710AR,115 datasheet, 2PB710AR,115 pinout, 2PB710AR,115 application, or 2PB710AR,115 equivalent, key selection criteria include verified PNP polarity, SC-59 thermal resistance (500 K/W), saturation voltage ≤ −600 mV at −300 mA/−30 mA drive, and guaranteed h_FE binning per marking code DR.

Technical Context

This device operates as a medium-speed, medium-current PNP switch or amplifier with fixed emitter-base and collector-base breakdown limits defined per IEC 60134. Its junction temperature rating of 150 °C and FR4-board thermal resistance of 500 K/W constrain continuous operation under ambient >85 °C without derating.

The 2PB710AR,115 exhibits specified transition frequency (f_T = 120 MHz) and collector capacitance (C_c ≤ 15 pF) under −50 mA/−10 V bias, confirming suitability for audio-frequency and low-MHz digital signal switching-not RF or high-speed logic.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−50 V - maximum safe collector-emitter voltage with base open; defines upper rail limit in PNP switch configurations.
I_C (DC)	−500 mA - continuous collector current rating; sets max load-handling capacity in linear or saturated operation.
h_FE	120–240 - DC current gain range at −150 mA/−10 V; enables predictable base drive sizing for switching.
V_CEsat	≤ −600 mV - collector-emitter saturation voltage at −300 mA/−30 mA; determines conduction loss in on-state.
f_T	120 MHz - transition frequency under −50 mA/−10 V; confirms usable bandwidth up to ~10–20 MHz in amplification.
R_{th j-a}	500 K/W - thermal resistance junction-to-ambient on FR4 PCB; requires heatsinking or derating above ~125 mW dissipation.
C_c	≤ 15 pF - collector capacitance at −10 V V_CB; impacts switching speed and high-frequency stability.

Pinout & Package

Package: SOT346 (SC-59), plastic surface-mounted, 3-lead package with standard lead pitch (0.95 mm) and footprint per JEDEC TO-236.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Current-controlled input terminal; reverse-biased for PNP turn-on; requires negative drive relative to emitter.
2	Emiter	Common reference terminal for PNP operation; connected to higher potential rail in typical switch layouts.
3	Collector	Output current terminal; sinks current when device is active; connects to load toward lower-potential node.

Key Features

Feature	Design Value
Guaranteed h_FE binning	Marking 'DR' certifies 120–240 h_FE range - eliminates design margin uncertainty in base resistor calculation.
Low V_CEsat	≤ −600 mV at −300 mA ensures <180 mW conduction loss - reduces thermal stress in compact power stages.
High f_T	120 MHz supports stable amplification up to ~15 MHz - suitable for audio preamps and fast-switching control signals.
Robust thermal spec	150 °C T_j rating with 500 K/W R_{th j-a} allows operation in industrial ambient up to 85 °C with proper layout.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP general purpose transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMBT3906LT1G	Lower I_C (−200 mA), lower V_CEO (−40 V), h_FE 100–300 (unbinned), SOT-23 package	Not suitable for >200 mA loads or >40 V rails; smaller footprint but higher R_{th j-a}	Select when space-constrained and load current ≤150 mA; verify thermal margin on FR4.
ZTX753	Higher I_C (−1 A), higher P_tot (1 W), TO-92 package, h_FE 100–800 (wide spread)	Through-hole only; no guaranteed h_FE bin; better for high-current analog but less predictable for digital switching	Choose for prototyping or high-current linear use where leaded assembly is acceptable and gain tolerance is secondary.

Compared with MMBT3906LT1G and ZTX753, the 2PB710AR,115 delivers balanced performance: guaranteed mid-range h_FE, −500 mA capability in compact SOT346, and proven thermal behavior on standard PCBs - making it optimal for volume production of cost-sensitive, medium-current PNP switching functions.

FAQ

What is the package type and lead count of the 2PB710AR,115?

The 2PB710AR,115 uses the SOT346 (SC-59) plastic surface-mount package with three leads. Pin 1 is base, Pin 2 is emitter, and Pin 3 is collector - matching JEDEC TO-236 outline and enabling automated placement on standard PCBs. This package offers a compact footprint while maintaining adequate thermal performance for its 250 mW power rating.

What does the 'DR' marking on the 2PB710AR,115 indicate?

The 'DR' marking on the 2PB710AR,115 identifies its specific h_FE bin: guaranteed DC current gain of 120–240 at −150 mA and −10 V. This binning allows precise base resistor selection without design margin overkill, improving consistency in production batches of PNP switching circuits.

Is the 2PB710AR,115 suitable for high-frequency signal amplification?

The 2PB710AR,115 has a transition frequency f_T of 120 MHz under −50 mA/−10 V conditions, supporting stable amplification up to ~15 MHz. It is appropriate for audio preamplifiers and low-MHz control signal conditioning but not for RF or GHz-range applications where parasitic capacitance and gain roll-off become limiting.

How does the thermal performance of the 2PB710AR,115 compare to similar SOT transistors?

The 2PB710AR,115 has a junction-to-ambient thermal resistance R_{th j-a} of 500 K/W when mounted on FR4 PCB - typical for SOT346 devices. At its 250 mW P_tot, this yields ~125 °C junction rise above ambient; designers must ensure board copper area and ambient temperature stay within limits to avoid exceeding the 150 °C T_j max.

What is the PNP complement to the 2PB710AR,115?

The NPN complement to the 2PB710AR,115 is the 2PD602A, also offered by Nexperia in SOT346 package. Both share matched voltage/current ratings and thermal characteristics, enabling complementary push-pull or differential pair designs without package or layout mismatch.
