Product details
Overview
PUMB1,135 from Nexperia is a dual PNP resistor-equipped transistor (RET) in SOT363 (SC-88) package, integrating two matched PNP transistors with built-in 22 kΩ input bias resistors (R1 = R2 = 22 kΩ) and R2/R1 ratio of 1.0. It delivers −100 mA output current per transistor, supports −50 V collector-emitter voltage, and is AEC-Q101 qualified for automotive signal conditioning and digital interface control.
For engineers reviewing the PUMB1,135 datasheet, PUMB1,135 pinout, PUMB1,135 application, or PUMB1,135 equivalent, this device serves as a space- and BOM-optimized replacement for discrete PNP pairs in low-power logic-level translation, microcontroller I/O buffering, and automotive body electronics where bias resistor matching, thermal derating (417 K/W per device), and reflow-only assembly are critical selection criteria.
Technical Context
The PUMB1,135 implements two monolithically integrated PNP transistors sharing no internal connection between collectors or emitters-each has independent base biasing via dedicated 22 kΩ resistors. Its VI(on) = −1.7 V (typ) and VI(off) = −1.1 V (typ) at IC = −5 mA define precise switching thresholds under 3.3 V/5 V logic drive.
Thermal performance is specified per device (300 mW total power dissipation at Tamb ≤ 25 °C) with Rth(j-a) = 417 K/W on FR4 PCB, enabling stable operation up to 150 °C junction temperature. The −100 nA ICEO leakage at VCE = −30 V ensures reliable off-state isolation in battery-backed systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Supports robust operation in 24 V automotive supply rails with margin against load-dump transients. |
| IO | −100 mA - Drives LED indicators, small relays, or logic inputs without external current-limiting resistors. |
| R1 / R2 | 22 kΩ ±30% - Enables direct 3.3 V/5 V MCU GPIO interfacing with predictable base current (≈150 µA at 3.3 V). |
| R2/R1 ratio | 0.8–1.2 - Ensures matched gain and switching symmetry between both transistors for differential or complementary use. |
| VCEsat | −150 mV (max) at IC = −10 mA, IB = −0.5 mA - Minimizes conduction loss in high-side switch applications. |
| fT | 180 MHz - Supports clean switching up to ~10 MHz digital signals without excessive rise/fall time degradation. |
| hFE | 60 (min) at VCE = −5 V, IC = −5 mA - Guarantees sufficient current gain for reliable saturation with standard logic drive. |
Pinout & Package
SOT363 (SC-88) surface-mount plastic package: 1.35 mm × 2.2 mm footprint, 0.65 mm pitch, 6-pin ultra-small outline with exposed pad not present; rated for reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND (emitter of TR1) | Common emitter reference for first transistor; connects directly to system ground plane for low-inductance return path. |
| 2 | input (base of TR1) | Logic input node for TR1; internally connected to 22 kΩ resistor R1 - accepts 0 V to +10 V drive without external biasing. |
| 3 | output (collector of TR2) | Active-low output of second transistor; sinks current when TR2 is on - used for inverted logic or pull-down functions. |
| 4 | GND (emitter of TR2) | Independent emitter terminal for TR2; allows separate grounding or local decoupling from TR1's emitter. |
| 5 | input (base of TR2) | Logic input for TR2; identical bias network to Pin 2 - enables synchronous or independent control of both transistors. |
| 6 | output (collector of TR1) | Primary active-low output of TR1; electrically isolated from Pin 3 - supports dual independent switch outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Dual PNP RET integration | Reduces PCB area by >60% vs. two discrete SOT23 PNP transistors + four external bias resistors. |
| AEC-Q101 qualification | Validated for automotive body control modules, door modules, and lighting ECU applications per stress test requirements. |
| Built-in matched bias resistors | Eliminates 4 external 22 kΩ resistors and associated placement/tolerance errors - improves production yield and design repeatability. |
| −100 mA per transistor rating | Supports direct driving of 5 V logic inputs, optocoupler LEDs, or small-signal MOSFET gates without amplification stages. |
| Low VI(on)/VI(off) hysteresis | Ensures clean logic-level transitions between −0.8 V and −2.5 V input thresholds - prevents chatter in noisy automotive environments. |
Applications
| Automotive Door Module | Industrial PLC Input Stage |
|---|---|
Use Scenario: Level-shifting and inversion of LIN bus wake-up signals into microcontroller GPIO pins. IC Role / Device Role / Timing Role: Dual PNP switch providing active-low signal conditioning with built-in biasing for 12 V vehicle bus compatibility.

Use Scenario: Isolating and conditioning analog front-end enable signals in portable ultrasound probe interfaces. IC Role / Device Role / Timing Role: Low-leakage (ICEO < −100 nA) PNP switch controlling power to precision ADC reference buffers. Use Value: Prevents reference drift during standby via guaranteed off-state isolation - improving measurement accuracy by ≥0.5 LSB over temperature range. |
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 |
|---|---|---|---|
| NSVD2P0232PDR2G | Higher VCEO (−60 V), lower R1/R2 (10 kΩ), SOT-563 package (smaller than SOT363) | Better suited for 48 V telecom systems; reduced bias current increases propagation delay by ~15 ns | Select when higher voltage margin or tighter board space is required, but verify VI(on) compatibility with 3.3 V logic. |
| EMX11T2R | PNP/NPN complement pair, same SOT-363, R1 = 47 kΩ, R2 = 10 kΩ | Enables push-pull output stages; mismatched R1/R2 limits use in matched-switch applications like differential sensing | Choose for complementary driver designs (e.g., half-bridge gate control), not for dual identical PNP switching. |
Compared with NSVD2P0232PDR2G and EMX11T2R, PUMB1,135 offers optimal balance of matched biasing (R1 = R2), AEC-Q101 qualification, and proven thermal derating (417 K/W) - making it the preferred choice for automotive and industrial dual-switch applications requiring channel-to-channel consistency and long-term reliability.

FAQ
What is the maximum allowable ambient temperature for continuous operation of PUMB1,135?
The PUMB1,135 supports continuous operation from −65 °C to +150 °C ambient temperature. At Tamb = 125 °C, its per-device power dissipation must be derated to ≤150 mW based on the 417 K/W thermal resistance curve - verified per JEDEC JESD51-2 standards on FR4 PCB with standard footprint.
Can PUMB1,135 be used in a push-pull configuration?
No - PUMB1,135 contains two PNP transistors only and lacks an NPN complement. For true push-pull output, use the PUMD2 (dual NPN RET) alongside PUMB1,135 or select the EMX11T2R (PNP/NPN pair in same SOT363 package) which provides complementary switching capability.
Is wave soldering permitted for PUMB1,135?
No - the datasheet explicitly states "reflow soldering is the only recommended soldering method." Wave soldering exceeds thermal limits of the SOT363 package and risks delamination or die damage; validated reflow profiles are provided in Figure 13 of the official Nexperia datasheet.
How does the R2/R1 ratio affect circuit behavior in PUMB1,135?
The R2/R1 ratio of 0.8–1.2 ensures matched base current division between the two transistors, enabling symmetrical switching characteristics and consistent hFE across channels. This is critical in applications like differential sensing or mirrored current sources where gain tracking within ±20% is required.
