Product details
Overview
2PA1774RM from Nexperia is a PNP general purpose transistor in SOT883 ultra-small leadless package (1.0 × 0.6 × 0.5 mm), rated for −40 V VCEO, −100 mA IC (DC), and 180–390 hFE at −1 mA IC; used in mobile communications, digital cameras, and PCMCIA card power switching.
For engineers reviewing the 2PA1774RM datasheet, 2PA1774RM pinout, 2PA1774RM application, or 2PA1774RM equivalent, key selection factors include its low-profile SOT883 footprint, verified DC current gain range, collector-emitter saturation voltage under −50 mA load, thermal resistance (290 K/W on FR4), and PNP polarity for high-side switch configurations.
Technical Context
This device operates as a silicon PNP bipolar junction transistor optimized for low-voltage, medium-frequency switching and amplification. Its design supports DC biasing with VEB ≤ −5 V and delivers stable hFE across −55 °C to +150 °C ambient.
The SOT883 package enables board space reduction to 1.3 mm × 0.9 mm while maintaining 430 mW power dissipation capability when mounted on FR4 with 1 cm² collector pad - matching SOT23 thermal performance in <50% footprint area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −40 V: Maximum safe collector-emitter reverse bias before breakdown; defines usable supply rail headroom in PNP switch designs. |
| IC (DC) | −100 mA: Continuous collector current rating; sets upper limit for steady-state load switching in portable devices. |
| hFE | 180–390 at −1 mA IC: Confirmed DC current gain range ensures predictable base drive requirements for reliable saturation. |
| VCE(sat) | ≤ −200 mV at −50 mA IC, −5 mA IB: Low saturation voltage minimizes conduction loss and self-heating in battery-powered circuits. |
| fT | 100 MHz: Transition frequency confirms suitability for low/medium-frequency AC signal amplification up to ~10 MHz practical bandwidth. |
| Rth(j-a) | 290 K/W (FR4, 1 cm² pad): Thermal resistance enables 430 mW power handling without active cooling in compact layouts. |
Pinout & Package
SOT883 is a leadless ultra-small plastic package (1.0 × 0.6 × 0.5 mm) with three solder lands; board space requirement is 1.3 mm × 0.9 mm. The package uses bottom-surface terminations only - no leads extend beyond the body perimeter.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input for forward-biased PNP operation; requires negative current relative to emitter to turn on. |
| 2 | Emiter | Common reference terminal; connected to higher potential (e.g., VCC) in high-side switch configuration. |
| 3 | Collector | Output terminal; sinks current to load when saturated; thermally enhanced via large copper pad (1 cm² recommended). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-compact footprint | 1.3 mm × 0.9 mm board area - enables dense layout in space-constrained mobile and wearable PCBs. |
| Leadless construction | No wire bonds or gull-wing leads - eliminates mechanical stress failure modes and improves reflow reliability. |
| Thermal performance parity | 430 mW Ptot on FR4 matches SOT23 despite 50% smaller size - validated under standard mounting conditions. |
| Wide temperature operation | Specified from −65 °C to +150 °C Tstg/Tj - supports automotive under-hood and industrial ambient environments. |
Applications
| Digital Camera Power Management | PCMCIA Card Voltage Switching |
|---|---|
Use Scenario: Controlling flash LED bias or sensor power rail in compact digital still cameras. IC Role / Device Role / Timing Role: PNP high-side switch enabling fast on/off control of 3.3 V or 5 V subsystems. Use Value: Low VCE(sat) (< −200 mV) reduces power loss and heat generation in thermally isolated camera modules. | Use Scenario: Enabling/disabling 3.3 V or 5 V interface power on PCMCIA cards during hot insertion. IC Role / Device Role / Timing Role: Level-shifted enable switch isolating host logic from peripheral power domain. Use Value: Verified hFE range (180–390) ensures robust base drive margin across production lots and temperature extremes. |
| Mobile Handset Audio Amplifier Bias | Wearable Sensor Signal Conditioning |
Use Scenario: Providing stable bias current to Class-A audio preamplifier stages in smartphones. IC Role / Device Role / Timing Role: DC current source with predictable hFE and low leakage (ICBO ≤ −100 nA at 25 °C). Use Value: Tight ICBO specification ensures minimal quiescent current drift over time and temperature in battery-critical systems. | Use Scenario: Amplifying low-level analog outputs from MEMS accelerometers or environmental sensors. IC Role / Device Role / Timing Role: Small-signal PNP amplifier stage operating at −1 mA IC with linear hFE response. Use Value: fT = 100 MHz supports clean amplification of sensor signals up to 10 MHz without phase distortion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP general purpose transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 2PA1774QM | Lower hFE range (120–270); otherwise identical ratings and package. | Suitable where lower gain tolerance is acceptable and cost sensitivity is higher. | Select when base drive margin is generous and tighter hFE binning is not required. |
| 2PA1774SM | Higher hFE range (270–560); same VCEO, IC, and package. | Preferred for low-base-current designs or where maximum gain consistency is critical. | Choose for ultra-low-power bias networks or precision current mirror topologies. |
Compared with 2PA1774QM and 2PA1774SM, the 2PA1774RM offers balanced hFE performance - sufficient for most portable electronics switching while avoiding overdesign or unnecessary cost premium associated with high-gain variants.

FAQ
What is the marking code for 2PA1774RM?
The top-side marking code for 2PA1774RM is "PA", laser-etched on the package surface per Nexperia's SOT883 standard. This code uniquely identifies the RM gain bin and distinguishes it from QM ("PB") and SM ("PC") variants within the same family.
Can 2PA1774RM be used as a direct replacement for SOT23 PNP transistors?
No - although thermal performance is comparable, the SOT883 package has different solder land geometry, no leads, and requires reflow profile adjustment. PCB footprint and stencil design must be updated; electrical behavior is functionally equivalent but mechanical fit is not drop-in.
What is the maximum allowable continuous collector current at 85 °C ambient?
At Tamb = 85 °C, derating applies: Ptot drops to ~320 mW (based on 290 K/W Rth(j-a) and 150 °C Tj(max)). With VCE(sat) ≈ −200 mV, max continuous IC is approximately −80 mA to maintain junction temperature ≤ 150 °C.
Is there an NPN complement to 2PA1774RM?
Yes - the NPN complement is the 2PC4617M series, specifically 2PC4617RM (marking "RA"), which shares identical SOT883 packaging, voltage/current ratings, and thermal characteristics, enabling matched pair design in push-pull or differential configurations.
