Product details
Overview
PUMB18 from Nexperia is a dual PNP resistor-equipped transistor (RET) in SOT363 (SC-88) package, configured as two independent PNP transistors with integrated bias resistors R₁ = 4.7 kΩ and R₂ = 10 kΩ. 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 PUMB18 datasheet, PUMB18 pinout, PUMB18 application, or PUMB18 equivalent, this device serves as a space-optimized, pick-and-place–friendly replacement for discrete PNP pairs in low-power logic-level shifting, LED driver enable control, and microcontroller I/O buffering where built-in biasing reduces BOM count and layout complexity.
Technical Context
The PUMB18 integrates two matched PNP transistors with monolithically embedded base bias networks-R₁ connects base to input, R₂ connects base to emitter-enabling direct TTL/CMOS-compatible switching without external resistors. Each transistor operates with VCEO = −50 V and IO = −100 mA under DC conditions.
Its SC-88 (SOT363) package provides six terminals with GND–input–output topology per transistor, supporting high-density routing in portable and automotive ECUs. Thermal resistance is 417 K/W per device on FR4 PCB, and fT reaches 180 MHz at IC = −10 mA, confirming suitability for medium-speed digital switching up to ~10 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage with open base; enables use in 24 V automotive supply rails with margin. |
| IO | −100 mA: Continuous DC output current per transistor; sufficient for driving LEDs, small relays, or logic inputs. |
| R₁ | 4.7 kΩ ±27%: Integrated input bias resistor; sets base current for standard logic-level drive (e.g., 3.3 V MCU GPIO). |
| R₂/R₁ ratio | 2.1 typ (1.7–2.6): Ensures stable saturation and predictable turn-off behavior across temperature and process variation. |
| VCE(sat) | −100 mV max at IC = −10 mA, IB = −0.5 mA: Low saturation voltage minimizes power loss in active-switching applications. |
| fT | 180 MHz typ at VCE = −5 V, IC = −10 mA: Confirms usable bandwidth for fast digital edge transitions and PWM control. |
| AEC-Q101 | Qualified: Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22-A110/A114. |
Pinout & Package
SOT363 (SC-88) is a 6-pin ultra-small surface-mount plastic package measuring 2.2 mm × 1.35 mm × 0.95 mm, optimized for high-density PCB layouts in space-constrained modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND (emitter) TR1 | Emitter connection of first PNP transistor; common reference node for its internal bias network. |
| 2 | input (base) TR1 | Input terminal for TR1; connects externally to logic signal and internally to R₁ (4.7 kΩ) and R₂ (10 kΩ). |
| 3 | output (collector) TR2 | Collector of second PNP transistor; active-low output node for load switching or level translation. |
| 4 | GND (emitter) TR2 | Emitter connection of second PNP transistor; electrically isolated from Pin 1 but same potential in typical usage. |
| 5 | input (base) TR2 | Input terminal for TR2; identical bias configuration to Pin 2, enabling independent dual-channel control. |
| 6 | output (collector) TR1 | Collector of first PNP transistor; complements Pin 3 for dual-output, non-inverting or inverting configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Dual PNP RET architecture | Two fully independent PNP transistors with matched R₁/R₂ networks reduce component count by 4× vs discrete equivalents. |
| AEC-Q101 qualification | Validated for automotive under-hood and body-control applications requiring −40 °C to +125 °C operation and long-term reliability. |
| Low VCE(sat) | ≤ −100 mV ensures <10 mW conduction loss at 100 mA, critical for thermally constrained modules and battery-powered systems. |
| SC-88 footprint compatibility | SOT363 package aligns with industry-standard reflow profiles and automated placement equipment, minimizing assembly cost and yield risk. |
| VI(on)/VI(off) thresholds | −1.5 V typ VI(on) and −0.9 V typ VI(off) provide robust noise immunity against 3.3 V logic rail fluctuations in noisy environments. |
Applications
| Automotive Door Module | Industrial PLC Input Isolation |
|---|---|
|
Use Scenario: Level-shifting and buffering of LIN bus wake-up signals into microcontroller GPIO pins. IC Role / Device Role / Timing Role: Dual-channel active-low switch translating 12 V wake pulses to 3.3 V logic levels while providing current limiting and ESD protection via built-in resistors.

| Consumer Wearable Power Sequencing | Medical Sensor Interface |
|
Use Scenario: Controlled enable/disable sequencing of multiple low-power sensor ICs during sleep/wake cycles. IC Role / Device Role / Timing Role: Dual low-side switch controlling VDD enable lines for MEMS accelerometers and environmental sensors. Use Value: −100 mV VCE(sat) limits voltage drop to <0.1 V at 50 mA, preserving regulation accuracy and extending battery life in coin-cell–powered devices. |

IC Role / Device Role / Timing Role: Low-noise PNP switch decoupling reference voltage sources during ADC sampling windows. Use Value: 3 pF collector capacitance and 180 MHz fT ensure minimal capacitive coupling and fast settling (<100 ns), maintaining signal fidelity in sub-µV biomedical measurements. |
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 |
|---|---|---|---|
| NSVD2T2227XV6T1G | PNP/PNP RET in SOT-563; R₁ = 22 kΩ, R₂ = 47 kΩ; lower IO (−50 mA); no AEC-Q101 rating. | Targeted at consumer portables only; unsuitable for automotive due to missing qualification and reduced current capability. | Select only for cost-sensitive, non-automotive designs where higher input impedance and lower drive strength are acceptable. |
| EMH11T2R | PNP/PNP RET in SOT-363; R₁ = 10 kΩ, R₂ = 10 kΩ; identical AEC-Q101 rating; VCEO = −40 V. | Lower voltage rating restricts use to ≤12 V systems; R₂/R₁ = 1.0 eliminates gain stabilization benefit of PUMB18's 2.1 ratio. | Prefer when interfacing with 3.3 V/5 V logic exclusively and board space allows for tighter VCEO margin. |
Compared with NSVD2T2227XV6T1G and EMH11T2R, PUMB18 uniquely balances −50 V ruggedness, −100 mA drive, AEC-Q101 compliance, and optimal R₂/R₁ ratio for stable saturation-making it the only choice for 24 V automotive body electronics requiring both reliability and design margin.

FAQ
What is the maximum operating junction temperature for PUMB18?
The absolute maximum junction temperature (Tj) for PUMB18 is 150 °C, validated per IEC 60134 limiting values. At ambient temperatures up to +85 °C, continuous operation at full −100 mA load requires derating to maintain Tj ≤ 150 °C, supported by the specified Rth(j-a) = 417 K/W per device on FR4 PCB.
Can PUMB18 be used in linear amplification mode?
No-PUMB18 is characterized and qualified exclusively for switching applications. Its built-in R₁/R₂ network fixes base biasing for saturated on/off operation, and parameters like hFE are specified only at IC = −10 mA with fixed IB; no small-signal AC characteristics (e.g., gm, Cob) are guaranteed for analog gain use.
Is the SOT363 package lead-free and RoHS compliant?
Yes-PUMB18 is manufactured in full compliance with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The SOT363 package uses matte tin (Sn) lead finish with no lead content exceeding 0.1 wt%, verified per JEDEC J-STD-020 moisture sensitivity level 1.
How does the R₂/R₁ ratio affect switching performance?
The R₂/R₁ ratio of 2.1 typ ensures sufficient base current for deep saturation (VCE(sat) ≤ −100 mV) while providing adequate reverse base-emitter bias during turn-off to minimize storage time. This ratio directly improves switching speed consistency across temperature and voltage variations compared to fixed-R or single-resistor RETs.
