Product details

Overview

2PB709ART,235 from Nexperia is a PNP general-purpose bipolar junction transistor in SOT23 (TO-236AB) surface-mount package, rated for −45 V V_CEO, −100 mA I_C, and DC current gain (h_FE) of 210–340 at −10 V V_CE and −2 mA I_C. It serves as a compact switching or amplification element in low-power analog and digital signal paths, such as level-shifting circuits in microcontroller I/O interfaces.

For engineers reviewing the 2PB709ART,235 datasheet, 2PB709ART,235 pinout, 2PB709ART,235 application, or 2PB709ART,235 equivalent, key selection criteria include verified PNP polarity, SOT23 footprint compatibility, guaranteed h_FE range under −10 V bias, thermal resistance (R_th(j-a) = 500 K/W), and −6 V V_EBO emitter-base rating for robust base drive design.

Technical Context

This device operates as a discrete PNP BJT with fixed polarity and no integrated biasing or protection circuitry. Its performance is defined by DC parameters including V_CEO = −45 V, I_C = −100 mA, and h_FE = 210–340, all measured under standardized conditions (T_amb = 25 °C, pulse test tp ≤300 µs).

Thermal behavior follows JEDEC-standard FR4 PCB mounting assumptions: R_th(j-a) = 500 K/W and R_th(j-sp) = 140 K/W. Electrical limits are governed by IEC 60134 absolute maximum ratings, with T_j max = 150 °C and storage temperature range −65 to +150 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−45 V - Maximum collector-emitter voltage before breakdown with base open; defines safe operating voltage headroom in PNP switch configurations.
I_C	−100 mA - Continuous collector current rating; sets upper limit for load-driving capability in linear or saturated operation.
h_FE	210–340 - DC current gain at V_CE = −10 V, I_C = −2 mA; determines required base drive current for target collector current.
V_CE(sat)	−500 mV - Collector-emitter saturation voltage at I_C = −100 mA, I_B = −10 mA; impacts conduction loss and power dissipation in switching mode.
f_T	70 MHz - Transition frequency at V_CE = −10 V, I_C = −1 mA; indicates usable bandwidth for small-signal amplification up to ~10 MHz.
R_th(j-a)	500 K/W - Junction-to-ambient thermal resistance on standard FR4 PCB; used to calculate temperature rise under given power dissipation.

Pinout & Package

2PB709ART,235 uses the SOT23 (TO-236AB) plastic surface-mount package: 3-pin, 1.3 mm × 2.9 mm footprint, 1.1 mm height, with gull-wing leads and standard solder pad layout per Nexperia's sot023 footprint guidelines.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Current-controlled input terminal; requires negative bias relative to emitter to turn on PNP device.
2	Emitter	Common reference terminal for PNP operation; typically connected to higher potential (e.g., V_CC) in switching applications.
3	Collector	Output terminal sourcing current when active; connects to load and lower-potential node (e.g., ground or signal return).

Key Features

Feature	Design Value
PNP polarity with −45 V V_CEO	Enables high-side switching in 3.3 V/5 V logic systems where emitter ties to supply rail and collector drives load to ground.
SOT23 package footprint	Supports automated placement and reflow on space-constrained PCBs; compatible with industry-standard pick-and-place and AOI inspection.
h_FE = 210–340 at −2 mA I_C	Ensures predictable base drive requirements across production lots, reducing need for trimming or feedback compensation.
V_EBO = −6 V rating	Allows safe reverse-biasing of base-emitter junction during fast turn-off or level-shift transitions without leakage degradation.

Applications

LED Driver Circuit

Microcontroller Level Shifter

Use Scenario: Driving 20 mA indicator LEDs from 3.3 V GPIO pins with inverted logic control.

IC Role / Device Role / Timing Role: PNP switch configured in common-emitter topology, sinking current from LED anode to V_CC while collector connects to LED cathode and ground.

Use Value: Low V_CE(sat) (−500 mV) minimizes voltage drop across transistor, preserving forward voltage margin for red/green LEDs at 3.3 V supply.

Use Scenario: Converting 1.8 V logic outputs to interface with 5 V legacy peripherals requiring active-low enable signals.

IC Role / Device Role / Timing Role: Inverting level translator using PNP emitter-follower configuration with pull-up resistor on emitter and base driven by low-voltage GPIO.

Use Value: Guaranteed h_FE ≥210 ensures reliable turn-on with minimal base current (<10 µA), reducing loading on weak-drive microcontroller outputs.

Low-Power Sensor Biasing

Relay Driver Interface

Use Scenario: Providing stable bias current to temperature-compensated NTC thermistor networks in battery-powered environmental monitors.

IC Role / Device Role / Timing Role: Constant-current source built with emitter resistor and base voltage reference, leveraging h_FE stability over −55 to +150 °C.

Use Value: Specified h_FE variation across temperature and IC = −2 mA ensures <±5% current drift in precision analog front-ends.

Use Scenario: Switching 12 V relay coils with 50 mA hold current in industrial control modules using 3.3 V MCU outputs.

IC Role / Device Role / Timing Role: High-side driver with emitter tied to 12 V rail, collector driving relay coil to ground, base controlled via current-limiting resistor.

Use Value: −45 V V_CEO rating safely absorbs inductive kickback spikes up to 40 V, eliminating need for external flyback diodes in cost-sensitive designs.

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
2PD601ART	NPN complement with +45 V V_CEO, +100 mA I_C, same SOT23 package and h_FE range.	Requires inverted control logic and low-side switching topology instead of high-side PNP configuration.	Select when circuit architecture favors NPN load-switching or when complementary pair design is needed.
BC807-40,215	Same PNP polarity, SOT23 package, but higher h_FE (250–630), identical V_CEO/I_C ratings, and tighter V_CE(sat) spec (−400 mV typical).	Delivers lower saturation loss and higher gain margin, suitable for higher-efficiency or lower-drive applications.	Prefer when optimizing for reduced base drive or improved thermal performance under sustained 100 mA loads.

Compared with 2PD601ART and BC807-40,215, the 2PB709ART,235 offers balanced gain and saturation performance in a mature, widely qualified PNP SOT23 device-ideal for cost-sensitive, non-critical switching where proven reliability and long-term availability outweigh marginal parameter improvements.

FAQ

Is the 2PB709ART,235 RoHS compliant and halogen-free?

Yes, the 2PB709ART,235 meets RoHS Directive 2011/65/EU requirements and is certified halogen-free per Nexperia's material declarations. The device uses lead-free matte tin (Sn) termination finish and complies with JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) for unlimited floor life at ≤30 °C/60% RH.

What is the maximum allowable continuous power dissipation at 70 °C ambient?

At T_amb = 70 °C, the derated total power dissipation is 150 mW, calculated using the linear derating curve: P_tot = 250 mW − [(70 − 25) × 0.5 mW/°C] = 150 mW. This assumes mounting on standard FR4 PCB with single-sided copper and tin-plated traces per datasheet condition [1].

Can the 2PB709ART,235 be used in linear amplifier configurations?

Yes, it supports small-signal amplification with f_T = 70 MHz and h_FE stability across I_C = 0.1–10 mA. However, its V_CE(sat) and thermal resistance limit use to low-gain, low-output-power stages (e.g., preamplifiers or buffer stages), not power output stages.

Does the marking code 'C5*' vary by manufacturing location?

Yes-the asterisk in 'C5*' denotes country of origin: '-' or 'p' = Hong Kong, 't' = Malaysia, 'W' = China. This marking is laser-etched on the top surface of the SOT23 package and does not affect electrical specifications or reliability performance.
