Product details
Overview
PEMB15 from Nexperia is a dual PNP resistor-equipped transistor (RET) in SOT666 package, integrating two matched PNP transistors with built-in 4.7 kΩ input bias resistors (R1 = R2) and 1:1 R2/R1 ratio. It delivers −100 mA output current per transistor, supports −50 V collector-emitter voltage, and is AEC-Q101 qualified for automotive signal conditioning and logic-level interface applications.
For engineers reviewing the PEMB15 datasheet, PEMB15 pinout, PEMB15 application, or PEMB15 equivalent, this device serves as a space- and BOM-optimized replacement for discrete PNP pairs in digital control, level shifting, and peripheral driver circuits where bias resistor matching and thermal derating on FR4 PCBs are critical design factors.
Technical Context
The PEMB15 integrates two independent PNP transistors sharing no internal connection between collectors or emitters-each has its own base input via dedicated R1 bias resistor and emitter tied to GND. The R2 resistor connects base to emitter internally, forming a monolithic resistor-equipped transistor structure that eliminates external bias networks.
It operates with VI(on) = −1.9 V (typ) at IC = −20 mA and VI(off) = −1.1 V (typ) at IC = −100 µA, enabling reliable TTL/CMOS-compatible switching. Its fT = 180 MHz (typ) at IC = −10 mA and VCE = −5 V confirms suitability for medium-speed digital switching up to ~10 MHz edge rates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage with open base; defines off-state blocking capability in high-side switch configurations. |
| IO | −100 mA - Continuous DC output current per transistor; sets maximum load drive capacity for LED drivers or logic buffers. |
| R1 | 4.7 kΩ (3.3–6.1 kΩ) - Integrated base-input bias resistor; eliminates need for external pull-up/pull-down and reduces layout area by ≥2 components per channel. |
| R2/R1 ratio | 1.0 (0.8–1.2) - Tight matching ensures consistent turn-on thresholds across both transistors; critical for balanced dual-channel operation. |
| hFE | 30 (min) at IC = −10 mA, VCE = −5 V - Minimum DC current gain; guarantees sufficient drive strength for saturated switching into 1 kΩ loads. |
| VCEsat | −150 mV (max) at IC = −10 mA, IB = −0.5 mA - Low saturation voltage minimizes power loss and self-heating in high-duty-cycle switching. |
| Ptot (per device) | 300 mW at Tamb ≤ 25 °C - Total power dissipation limit for both transistors; requires thermal derating above 25 °C per 417 K/W junction-to-ambient resistance. |
Pinout & Package
SOT666 is a 6-pin ultra-small flat-lead surface-mount package (1.7 × 1.5 mm, 0.65 mm pitch), optimized for automated placement and reflow soldering only. Pin 1 is marked by an index notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND (emitter of TR1) | Common emitter reference for first transistor; must be connected to system ground or low-impedance return path. |
| 2 | input (base of TR1) | Signal input node for TR1; driven through internal R1; compatible with 0 V to −3 V logic levels. |
| 3 | output (collector of TR2) | Active-low output node of second transistor; sinks current when TR2 is on; used for inverted logic or pull-down functions. |
| 4 | GND (emitter of TR2) | Common emitter reference for second transistor; electrically isolated from Pin 1 but typically tied to same ground plane. |
| 5 | input (base of TR2) | Signal input node for TR2; identical biasing to Pin 2; enables synchronous dual-channel control. |
| 6 | output (collector of TR1) | Active-low output node of first transistor; complements Pin 3; supports push-pull or complementary switching topologies. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM ≥2 kV); enables use in engine control, body electronics, and ADAS modules. |
| Built-in matched bias resistors | R1 = R2 = 4.7 kΩ ±28% with R2/R1 = 1.0 ±20%; eliminates manual resistor selection, placement, and matching tolerance stack-up in dual-channel designs. |
| −100 mA per transistor output | Supports direct driving of LEDs, relays, or logic inputs without external amplification; reduces bill-of-materials count by up to 4 passive components per channel. |
| Low VCEsat (−150 mV max) | Minimizes conduction loss and thermal rise in high-duty-cycle applications such as PWM dimming or continuous sensor interface buffering. |
| SOT666 footprint | 1.7 × 1.5 mm outline with 0.65 mm lead pitch; compatible with standard 0402-class pick-and-place equipment and IPC-7351B land patterns. |
Applications
| Automotive Door Module Control | Industrial PLC Input Conditioning |
|---|---|
|
Use Scenario: Level-shifting and current-limiting interface between 3.3 V microcontroller GPIO and 12 V automotive door lock actuator solenoids. IC Role / Device Role / Timing Role: Dual PNP RET acts as two independent active-low drivers, sinking solenoid current while providing logic-level compatibility and overvoltage protection. Use Value: Eliminates four external resistors and two discrete transistors; reduces PCB area by 35% versus discrete solution and meets AEC-Q101 requirements without additional qualification effort. |
Use Scenario: Converting 24 V industrial field signals into clean 5 V logic levels for PLC digital input cards operating in noisy factory environments. IC Role / Device Role / Timing Role: Each PNP channel functions as a high-side signal conditioner, clamping input transients and providing controlled current sink into optocoupler LED anodes. Use Value: Built-in R1/R2 resistors ensure precise threshold setting (VI(on)/VI(off)) across temperature; reduces susceptibility to EMI-induced false triggering by >15 dB compared to unbuffered inputs. |
| Consumer Appliance Keypad Interface | Medical Diagnostic Equipment Logic Buffering |
|
Use Scenario: Scanning matrix keypad rows in battery-powered smart thermostats where low quiescent current and board space are critical constraints. IC Role / Device Role / Timing Role: Dual RET provides row activation with integrated pull-down biasing, enabling fast scan cycles (<10 µs transition) while maintaining <1 µA standby leakage. Use Value: Reduces component count by 50% versus discrete PNP + resistor solution; achieves 2× faster key response time due to lower input capacitance (Cc = 3 pF) and matched hFE. |
Use Scenario: Isolating and buffering analog front-end control signals in portable ultrasound devices requiring strict EMI immunity and zero cross-talk between channels. IC Role / Device Role / Timing Role: One RET channel drives ADC reference enable; the other controls multiplexer select lines-both operate synchronously with sub-100 ns propagation delay. Use Value: Matched R2/R1 ratio ensures identical turn-on timing across channels; prevents transient coupling during simultaneous switching, preserving signal integrity in sensitive analog paths. |
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 |
|---|---|---|---|
| PUMB15 | Same electrical specs but in SOT363 (SC-88) package; smaller footprint (2.0 × 1.25 mm), higher thermal resistance (625 K/W per transistor vs. 417 K/W for PEMB15). | Better suited for ultra-dense consumer PCBs where space is more constrained than thermal margin; not recommended for sustained >50 mA loads without derating. | Select PUMB15 only when board area savings outweigh thermal performance trade-offs; verify reflow profile compatibility with SC-88's finer pitch (0.65 mm). |
| EMB15 | Legacy NXP part number superseded by PEMB15; identical pinout, specs, and qualification-only differs in marking code (5D vs. older codes) and packaging traceability. | No functional difference; used interchangeably in legacy designs; lacks updated AEC-Q101 documentation traceability in newer audits. | Prefer PEMB15 for new designs requiring full AEC-Q101 compliance documentation and long-term supply assurance from Nexperia. |
Compared with PUMB15, PEMB15 offers superior thermal performance (417 vs. 625 K/W) and larger solder land area for improved mechanical reliability, while EMB15 provides identical functionality but lacks current compliance documentation-making PEMB15 the optimal choice for automotive and industrial programs requiring audit-ready sourcing.

FAQ
Is PEMB15 pin-compatible with PUMB15?
No-PEMB15 uses SOT666 (6-pin, 0.65 mm pitch, 1.7 × 1.5 mm), while PUMB15 uses SOT363 (6-pin, 0.65 mm pitch, 2.0 × 1.25 mm). Though both have identical pin numbering and function mapping, their footprints differ in pad length, width, and thermal pad layout. PCB redesign is required for substitution.
What is the maximum allowable ambient temperature for continuous 100 mA operation?
At 100 mA per transistor, total power dissipation reaches ~15 mW × 2 = 30 mW. With Rth(j-a) = 417 K/W (per device), junction temperature rise is ~12.5 °C. Given Tj(max) = 150 °C, maximum ambient is 137.5 °C-but derating per Figure 1 limits usable Tamb to ≤125 °C for 300 mW-rated operation under real-world PCB conditions.
Can PEMB15 replace two separate BC807-40 transistors?
Yes-with caveats. PEMB15 matches BC807-40's hFE (min 250), VCEO (−45 V), and IC(max) (−500 mA) only partially: its hFE is lower (30 min), but it adds integrated biasing. It replaces BC807-40 + two 4.7 kΩ resistors per channel, reducing layout complexity-but requires verifying VI(on)/VI(off) thresholds match your logic family's drive capability.
Does PEMB15 support wave soldering?
No-reflow soldering is the only recommended method per Nexperia's datasheet (Section 11). Wave soldering is explicitly unsupported due to thermal stress risks on the SOT666 package and potential damage to internal resistor elements. Use reflow profiles compliant with J-STD-020, peak temp ≤260 °C.
