Product details

Overview

PEMB16 from Nexperia is a dual PNP resistor-equipped transistor (RET) in SOT666 package, featuring integrated bias resistors R1 = 22 kΩ and R2 = 47 kΩ, V_CEO = −50 V, I_O = −100 mA, and h_FE ≥ 80 at −5 mA/−5 V. It functions as a compact, pre-biased digital switch for low-current peripheral interfacing in space-constrained PCBs.

For engineers reviewing the PEMB16 datasheet, PEMB16 pinout, PEMB16 application, or PEMB16 equivalent, this device is selected for simplified logic-level translation, IC input control, and replacement of discrete BJT + resistor networks in automotive body electronics, industrial I/O modules, and consumer appliance microcontroller interfaces.

Technical Context

This dual PNP RET integrates two matched PNP transistors with dedicated base bias networks-each with R1 (input resistor) and R2 (base-emitter feedback resistor)-enabling direct TTL/CMOS-compatible switching without external bias components. The R2/R1 ratio of 2.1 typ ensures stable saturation under varying temperature and supply conditions.

Designed for digital switching-not linear amplification-the device exhibits V_CEsat ≤ −150 mV at I_C = −10 mA/I_B = −0.5 mA and VI(on) = −1.1 V typ at I_C = −2 mA, supporting reliable low-voltage logic drive in 3.3 V and 5 V systems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−50 V: Maximum safe collector-emitter voltage before breakdown; enables use in 24 V industrial control rails with margin.
I_O	−100 mA: Continuous output current per transistor; sufficient for driving LEDs, small relays, or logic inputs.
R1	22 kΩ ±30%: Input bias resistor value; sets base current for predictable turn-on with standard MCU GPIOs.
R2/R1	2.1 typ (1.7–2.6): Feedback-to-input resistor ratio; stabilizes operating point against β variation and temperature drift.
h_FE	≥80 at −5 mA/−5 V: Minimum DC current gain; ensures robust saturation with low base drive overhead.
V_CEsat	≤ −150 mV at −10 mA/−0.5 mA: Low saturation voltage reduces power loss and heat generation in switching mode.
P_tot (per device)	300 mW at T_amb ≤ 25 °C: Total dissipation limit for both transistors; supports continuous operation in compact SOT666 footprint.

Pinout & Package

SOT666 plastic surface-mounted package (6-lead, 1.7 × 1.5 mm), thermally optimized for FR4 PCBs with single-sided copper; R_th(j-a) = 416 K/W per device.

Pin/Terminal	Circuit Role	Design Meaning
1	GND (emitter) TR1	Emitter connection for first PNP transistor; common reference node for bias network and load return path.
2	input (base) TR1	Input terminal for TR1; connects to logic signal source through internal R1; no external pull-up required.
3	output (collector) TR2	Output node of second PNP transistor; sinks current when TR2 is active; used for inverted logic output or level shifting.
4	GND (emitter) TR2	Emitter connection for second PNP transistor; electrically isolated from Pin 1 but same potential in typical layout.
5	input (base) TR2	Input terminal for TR2; independently biased via its own R1–R2 network; enables dual-channel asynchronous control.
6	output (collector) TR1	Output node of first PNP transistor; complements Pin 3; allows cross-coupled or independent switching configurations.

Key Features

Feature	Design Value
Dual PNP RET topology	Two independent, pre-biased PNP transistors in one package; eliminates four external resistors and reduces PCB area by >60% vs discrete solution.
Matched R1/R2 networks	R1 = 22 kΩ ±30%, R2/R1 = 2.1 typ; ensures consistent turn-on thresholds and thermal stability across both channels.
Low V_CEsat	≤ −150 mV at rated current; minimizes conduction loss and self-heating in battery-powered or thermally constrained applications.
Wide operating temperature	T_amb = −65 °C to +150 °C; qualified for under-hood automotive and industrial environments without derating.
Reflow-solder compatible	Qualified for lead-free reflow only; avoids mechanical stress and intermetallic formation risks associated with wave soldering.

Applications

Automotive Body Control Module

Industrial PLC Digital Input Stage

Use Scenario: Driving LED status indicators and small solenoid valves from 3.3 V microcontroller GPIOs in door module ECUs.

IC Role / Device Role / Timing Role: Dual-channel level-shifting switch translating MCU logic outputs to 12 V loads with built-in current limiting and polarity inversion.

Use Value: Eliminates six discrete passives per channel, reducing BOM count, placement cost, and failure points while maintaining <1 µs propagation delay.

Use Scenario: Conditioning 24 V field signals into clean 5 V logic levels for FPGA-based I/O expansion cards.

IC Role / Device Role / Timing Role: Input buffer and voltage translator; each PNP channel isolates and clamps incoming signals before FPGA input protection diodes.

Use Value: Built-in R1/R2 provides precise input threshold (VI(on) = −1.1 V) and noise immunity (VI(off) = −0.8 V), eliminating external hysteresis design.

Consumer Appliance Microcontroller Interface

Medical Diagnostic Equipment Power Sequencing

Use Scenario: Enabling/disabling auxiliary power rails (e.g., sensor bias, display backlight) in smart thermostats using low-power MCU outputs.

IC Role / Device Role / Timing Role: Low-side enable switch with fast turn-off (ICEO ≤ −1 µA) and guaranteed off-state isolation between subsystems.

Use Value: −50 V V_CEO rating accommodates transient spikes on shared 5 V rails; GND-isolated emitters prevent ground-loop coupling.

Use Scenario: Controlling sequencing of isolated DC-DC converter enables in portable ultrasound units requiring strict power-up order.

IC Role / Device Role / Timing Role: Precision timing element in RC-delayed enable chain; R1/R2 ratio ensures repeatable turn-on delay independent of β variation.

Use Value: Matched resistor tolerances (±30%) and thermal tracking (<±50 ppm/°C) maintain sequence timing accuracy across −20 °C to +70 °C ambient.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual PNP resistor-equipped transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
PEMB20,115	R1 = 47 kΩ, R2 = 47 kΩ (R2/R1 = 1.0); lower input sensitivity; higher VI(on) = −1.5 V typ.	Better suited for 5 V CMOS drive where higher input threshold improves noise margin.	Select when interfacing with legacy 5 V logic families requiring stronger high-state rejection.
PUMD16,115	SOT363 (SC-88) package; identical electrical specs but 20% smaller footprint and 15% higher R_th(j-a) (625 K/W per transistor).	Preferred for ultra-dense layouts where board area is critical and thermal budget permits.	Select when PCB real estate is constrained and peak power dissipation remains below 150 mW per channel.

Compared with PEMB20,115, PEMB16 offers higher input sensitivity and faster turn-on in 3.3 V systems; compared with PUMD16,115, it delivers superior thermal performance in high-density industrial modules where sustained 100 mA switching occurs.

FAQ

What is the maximum continuous current per channel for PEMB16?

The PEMB16 supports −100 mA continuous output current per transistor under T_amb ≤ 25 °C with proper PCB copper area. Derating is required above 25 °C ambient; at 70 °C, max current drops to −65 mA per channel based on its 300 mW total device power limit and 416 K/W thermal resistance.

Can PEMB16 be used in linear amplifier configurations?

No-PEMB16 is not characterized or specified for linear operation. Its datasheet provides only switching parameters (V_CEsat, h_FE at saturation, VI(on)/VI(off)), and the integrated bias resistors fix the operating point for digital on/off behavior. Linear gain, frequency response, or distortion data are not provided.

Is the SOT666 package RoHS-compliant and lead-free?

Yes-PEMB16 is manufactured in full compliance with RoHS Directive 2011/65/EU and uses lead-free terminations qualified for standard Pb-free reflow soldering profiles (JEDEC J-STD-020). The package marking "5G" and ordering code suffix "115" confirm RoHS-compliant production lot traceability.

How does the R2/R1 ratio affect circuit behavior?

The R2/R1 ratio of 2.1 typ determines the degree of base-emitter feedback, which stabilizes the transistor's operating point against β variation and temperature drift. A higher ratio increases off-state leakage immunity but slightly raises VI(on); this specific ratio balances noise rejection and drive sensitivity for 3.3 V logic interfaces.
