Product details
Overview
PEMB20 from Nexperia is a dual PNP resistor-equipped transistor (RET) in SOT666 package, rated for −50 V VCEO, −100 mA IO, with integrated R1 = R2 = 2.2 kΩ bias resistors. It functions as a compact, pre-biased digital switch pair for low-current logic interfacing and peripheral control in space-constrained PCBs.
For engineers reviewing the PEMB20 datasheet, PEMB20 pinout, PEMB20 application, or PEMB20 equivalent, this device is selected for simplified gate/input driving in 3.3 V/5 V digital systems where component count reduction and consistent turn-on behavior are critical - especially in battery-powered sensors and microcontroller I/O expanders.
Technical Context
The PEMB20 integrates two matched PNP transistors with on-chip base-emitter bias networks, eliminating external resistors while maintaining predictable VI(on)/VI(off) thresholds across temperature (−40 °C to +100 °C). Each transistor operates independently with dedicated GND, input, and output terminals.
Its dual-transistor topology supports parallel or cascaded switching configurations; R2/R1 ratio of 1.0 ±0.2 ensures stable current gain (hFE ≥30 at −20 mA) and low VCE(sat) (≤−150 mV @ −10 mA/−0.5 mA), enabling reliable saturation in low-voltage logic-level translation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage before breakdown; enables use in 24 V industrial logic rails with margin. |
| IO | −100 mA: Continuous output current per transistor; sufficient for driving LEDs, small relays, or MCU inputs. |
| R1 | 2.2 kΩ ±30%: Integrated base pull-up resistor; sets defined input threshold and eliminates external bias components. |
| VCE(sat) | ≤−150 mV @ IC = −10 mA, IB = −0.5 mA: Ensures minimal voltage drop in saturated switching, preserving signal integrity. |
| hFE | ≥30 @ VCE = −5 V, IC = −20 mA: Guarantees adequate current amplification for robust digital switching without marginal drive. |
| VI(on) | −2.0 to −1.6 V @ VCE = −0.3 V: Defines precise turn-on voltage range for compatibility with standard CMOS/TTL logic levels. |
Pinout & Package
SOT666 ultra-small flat-lead plastic package (1.6 mm × 1.2 mm × 0.55 mm, 0.5 mm pitch); 6-pin surface-mount outline optimized for high-density routing and reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1; common reference for first transistor's bias network. |
| 2 | I1 | Base input for TR1; internally connected to R1 and R2 node; accepts logic-level signals. |
| 3 | O2 | Collector output for TR2; active-low switching node for second channel. |
| 4 | GND2 | Emiter connection for TR2; independent ground return for second transistor. |
| 5 | I2 | Base input for TR2; identical bias structure to I1; enables synchronous dual-channel control. |
| 6 | O1 | Collector output for TR1; primary active-low output; paired with O2 for dual independent loads. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent PNP RETs | Two fully isolated transistor channels with separate emitters, inputs, and collectors - supports asymmetric load grounding. |
| Matched internal bias network | R1 = R2 = 2.2 kΩ ±30%, R2/R1 = 1.0 ±0.2 - ensures consistent VI(on)/VI(off) and hFE across both transistors. |
| Low thermal resistance | Rth(j-a) = 416 K/W (per device on FR4) - enables 300 mW total power dissipation at 25 °C ambient without heatsinking. |
| Wide operating temperature | −65 °C to +150 °C storage and ambient range - qualified for industrial environments including extended cold start and hot chassis operation. |
Applications
| LED Driver Interface | Microcontroller I/O Expander |
|---|---|
|
Use Scenario: Driving multiple status LEDs from a 3.3 V MCU GPIO with limited sink current capability. IC Role / Device Role / Timing Role: Dual active-low switch providing controlled current paths to LED anodes tied to VCC. Use Value: Eliminates six external resistors (two per LED), reduces BOM count by 75%, and guarantees uniform brightness via matched hFE and VCE(sat). |
Use Scenario: Extending GPIO count on a resource-constrained ARM Cortex-M0+ design using discrete logic-level translation. IC Role / Device Role / Timing Role: Level-shifting buffer between 1.8 V sensor interface and 5 V display controller inputs. Use Value: VI(on) ≤ −1.6 V ensures clean turn-on with 1.8 V logic; low VCE(sat) preserves noise margin in 5 V receiver thresholds. |
| Low-Power Sensor Enable Control | Legacy TTL Input Interface |
|
Use Scenario: Enabling/disabling analog sensor modules (e.g., temperature, humidity) during sleep cycles in portable IoT nodes. IC Role / Device Role / Timing Role: Power-gating switch controlling VCC to sensor ICs via emitter-follower configuration. Use Value: −100 mA rating supports typical sensor peak currents; GND1/GND2 isolation prevents ground-loop interference between sensor domains. |
Use Scenario: Interfacing modern low-power MCUs with legacy 5 V TTL peripherals requiring active-low enable signals. IC Role / Device Role / Timing Role: Logic-compatible inverter replacing discrete transistor-resistor pairs in bus enable lines. Use Value: Built-in R1/R2 delivers guaranteed VI(off) ≥ −1.2 V, ensuring >2.0 V noise immunity against TTL high-state glitches. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual PNP RET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEMD20 | PNP/NPN complementary pair (not dual PNP); R1 = 2.2 kΩ, R2 = 47 kΩ; different VI(on) profile. | Used where one channel requires sourcing (NPN) and one sinking (PNP), e.g., push-pull level shifters. | Select PEMD20 only when mixed polarity switching is required; not interchangeable with PEMB20 due to topology mismatch. |
| PEMH20 | NPN/NPN dual RET; same package and footprint; R1 = R2 = 2.2 kΩ; VCEO = +50 V, IO = +100 mA. | Preferred for active-high switching, open-collector pull-ups, or interfacing with positive logic systems. | Choose PEMH20 when driving loads referenced to ground (e.g., N-channel MOSFET gates); pinout differs - verify layout compatibility. |
Compared with PEMD20 and PEMH20, PEMB20 uniquely provides dual PNP topology with matched biasing, making it the only option for dual active-low, high-side switching with shared or isolated emitters - essential for rail-to-rail logic inversion and negative supply domain control.

FAQ
What is the maximum allowable continuous current per channel?
The PEMB20 supports −100 mA continuous output current per transistor under Tamb ≤ 25 °C with proper PCB thermal relief. Derating applies above 25 °C per the 416 K/W junction-to-ambient thermal resistance curve; at 75 °C ambient, max current drops to approximately −65 mA per channel to maintain Tj ≤ 150 °C.
Can PEMB20 be used in a common-emitter configuration?
Yes - pins 1 (GND1) and 4 (GND2) serve as independent emitter terminals, allowing each transistor to operate in common-emitter mode with collector outputs at pins 6 (O1) and 3 (O2). This configuration enables standard active-low switching with load connected between VCC and O1/O2.
Is the SOT666 package compatible with standard reflow profiles?
Yes - Nexperia specifies reflow soldering as the only recommended method for SOT666. The package supports JEDEC J-STD-020-compliant lead-free reflow profiles, with peak temperatures up to 260 °C. Footprint dimensions (2.75 mm × 2.45 mm land pattern) and stencil aperture data are provided in Figure 9 of the datasheet.
How does the built-in R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 1.0 ±0.2 directly determines the internal base current division, stabilizing hFE and reducing sensitivity to process variation. This ensures consistent VI(on) (−2.0 to −1.6 V) and VI(off) (−1.2 to −0.5 V) across temperature and unit-to-unit, critical for deterministic logic-level translation without external trimming.
