Product details
Overview
PEMB24 from Nexperia is a dual PNP resistor-equipped transistor (RET) in SOT666 package, integrating two matched PNP transistors each with 100 kΩ input bias resistor (R1) and 100 kΩ feedback resistor (R2), rated for −50 V VCEO, −20 mA IO, and operating across −65 °C to +150 °C ambient. It serves as a compact, pre-biased logic-level switch for digital interface buffering and low-current peripheral control.
For engineers reviewing the PEMB24 datasheet, PEMB24 pinout, PEMB24 application, or PEMB24 equivalent, this page delivers verified electrical parameters, validated dual-transistor pin mapping, real-world use cases in IC input control and peripheral drivers, and confirmed alternatives with documented R1/R2 ratio and voltage tolerance differences.
Technical Context
The PEMB24 integrates two independent PNP transistors-TR1 and TR2-each with built-in base-emitter bias resistors (R1 = 100 kΩ, R2 = 100 kΩ) enabling direct TTL/CMOS-compatible switching without external bias networks. Its R2/R1 ratio of 1.0 ±0.2 ensures predictable saturation behavior under varying temperature conditions.
Each transistor supports −50 V collector-emitter breakdown (V(BR)CEO), −150 mV VCE(sat) at IC = −5 mA / IB = −0.25 mA, and exhibits hFE ≥80 at −5 mA, making it suitable for low-power digital signal inversion and level translation where space-constrained PCB layout demands component count reduction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage before breakdown; enables use in 3.3 V–24 V logic interface rails with margin. |
| IO | −20 mA: Continuous output current per transistor; sufficient for driving LED indicators, small relays, or CMOS/TTL inputs. |
| R1 | 100 kΩ ±30 %: Integrated base pull-up resistor; eliminates need for discrete biasing and reduces BOM count by one resistor per channel. |
| R2/R1 Ratio | 1.0 ±0.2: Ensures stable on-state gain and consistent turn-on threshold across temperature (−40 °C to +100 °C). |
| VCE(sat) | −150 mV @ IC = −5 mA: Low saturation voltage minimizes power loss and heat generation in high-duty-cycle switching. |
| hFE | ≥80 @ VCE = −5 V, IC = −5 mA: Sufficient DC current gain to guarantee reliable switching with standard logic drive levels. |
| Ptot (per device) | 300 mW @ Tamb ≤ 25 °C: Total dissipation limit for both transistors on FR4 PCB; defines thermal derating envelope for sustained operation. |
Pinout & Package
SOT666 ultra-small flat-lead plastic package: 1.6 mm × 1.2 mm × 0.55 mm body, 0.5 mm pitch, 6-terminal 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 node for first transistor's current path. |
| 2 | I1 | Base input for TR1; accepts logic-high (≤ −0.5 V off-state) or logic-low (≥ −1.6 V on-state) signals directly. |
| 3 | O2 | Collector output for TR2; active-low switched output referenced to GND2 (Pin 4). |
| 4 | GND2 | Emiter connection for TR2; isolated ground return for second transistor's current path. |
| 5 | I2 | Base input for TR2; electrically identical to I1 but independently controllable for dual-channel operation. |
| 6 | O1 | Collector output for TR1; active-low switched output referenced to GND1 (Pin 1). |
Key Features
| Feature | Design Value |
|---|---|
| Dual PNP RET architecture | Two fully independent PNP transistors with matched internal R1/R2 networks reduce footprint vs. discrete solutions by >40 %. |
| Integrated 100 kΩ bias resistors | Eliminates four external resistors in typical dual-buffer designs, cutting pick-and-place steps and assembly cost. |
| −150 mV VCE(sat) at −5 mA | Enables <100 µW static power per channel in saturated state, critical for battery-powered sensor nodes. |
| −50 V VCEO rating | Supports industrial I/O interfacing up to 24 V supply rails while maintaining safety margin against transients. |
| −65 °C to +150 °C operating range | Validated performance across automotive under-hood and industrial control environments without derating. |
Applications
| LED Indicator Driver | Microcontroller GPIO Expander |

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 |
|---|---|---|---|
| PEMD24 | PNP/NPN complement: TR1 = PNP, TR2 = NPN; R1 = 100 kΩ, R2 = 100 kΩ; same VCEO/IO ratings. | Required where mixed-signal level translation (e.g., push-pull output stage) is needed instead of dual-sink configuration. | Select when designing complementary output drivers or bidirectional bus buffers requiring both sourcing and sinking capability. |
| PEMH24 | NPN/NPN version: TR1/TR2 both NPN; identical R1/R2 values and package; VCEO = +50 V, IO = +20 mA. | Used in positive-rail logic systems (e.g., 5 V microcontrollers) where active-high switching is preferred over active-low. | Choose for compatibility with existing NPN-based schematics or where supply-referenced switching simplifies PCB routing. |
Compared with PEMD24 and PEMH24, the PEMB24 provides strictly dual-PNP functionality ideal for grounded-load configurations in negative-rail or low-side switching applications-offering superior noise immunity in industrial sensor interfaces where emitter-follower stability matters more than rail flexibility.

FAQ
Is PEMB24 pin-compatible with PEMH24 or PEMD24?
No. While all three share the SOT666 package and 6-pin layout, their internal transistor polarities differ: PEMB24 is PNP/PNP, PEMD24 is PNP/NPN, and PEMH24 is NPN/NPN. Pin functions (e.g., GND1, I1, O1) map to different internal structures-swapping them without schematic revision causes functional failure.
What is the maximum allowable input voltage at I1 or I2 pins?
The absolute maximum input voltage is −40 V to +10 V per the datasheet Limiting Values table. However, for reliable on/off operation, VI(on) is specified between −3.0 V and −1.6 V, and VI(off) between −1.2 V and −0.5 V at 25 °C-exceeding these ranges risks undefined switching behavior or latch-up.
Can PEMB24 be used in analog amplification applications?
No. The PEMB24 is designed exclusively for digital switching: its integrated resistors fix bias points, and hFE is only guaranteed under switching conditions (VCE = −5 V, IC = −5 mA). No small-signal gain, bandwidth, or linearity specifications are provided-use dedicated general-purpose PNP transistors for amplification.
Does PEMB24 require external decoupling capacitors?
No. As a DC-coupled switching device with no internal oscillators or high-speed logic, PEMB24 does not require decoupling. However, a 100 nF ceramic capacitor near the power entry point of the PCB section hosting multiple PEMB24 units helps suppress supply bounce during simultaneous switching events.
