Product details
Overview
2PD1820AS,115 from Nexperia is an NPN general-purpose bipolar junction transistor in SOT323 (SC-70) package, rated for 50 V VCEO, 500 mA IC, and 600 mV VCEsat at 300 mA/30 mA drive; used in portable equipment switching and low-power amplification circuits.
For engineers reviewing the 2PD1820AS,115 datasheet, 2PD1820AS,115 pinout, 2PD1820AS,115 application, or 2PD1820AS,115 equivalent, this page delivers verified electrical specs, thermal resistance (625 K/W), DC current gain range (170–340 at 150 mA), collector capacitance (15 pF), and transition frequency (150 MHz) - all critical for discrete BJT selection in space-constrained designs.
Technical Context
This device operates as a silicon NPN BJT with fixed three-terminal topology (base/emitter/collector), optimized for linear amplification and saturated switching in low-voltage, moderate-current applications. Its hFE binning (AS = 170–340 @ IC = 150 mA, VCE = 10 V) ensures predictable DC bias stability across production lots.
The SOT323 package enables surface-mount integration on FR4 PCBs with Rth j-a = 625 K/W, while its 15 pF Cc and 150 MHz fT support audio-frequency and low-speed digital switching up to ~10 MHz without significant phase lag or gain roll-off.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage under open-base condition; defines upper rail limit in switch/amplifier stages. |
| IC (DC) | 500 mA - Continuous collector current handling; supports load switching up to ~250 mW dissipation at room ambient. |
| VCEsat | 600 mV max @ IC = 300 mA, IB = 30 mA - Low saturation voltage minimizes conduction loss in battery-powered switch applications. |
| hFE | 170–340 @ IC = 150 mA, VCE = 10 V - Tight DC current gain bin ensures consistent base drive requirements across units. |
| fT | 150 MHz - Transition frequency confirms usable gain-bandwidth for audio preamps and low-speed logic interface buffering. |
| Cc | 15 pF @ VCB = 10 V - Collector junction capacitance impacts high-frequency response and switching speed in pulse applications. |
| Rth j-a | 625 K/W - Thermal resistance on FR4 board limits power handling to ~200 mW at Tamb = 25 °C before exceeding 150 °C junction temperature. |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package: 1.35 mm × 1.15 mm footprint, 0.95 mm height, 3-lead single-row configuration with gull-wing terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Current-controlled input terminal; requires ~30 mA drive for full saturation at 300 mA collector load. |
| 2 | Emiter | Common reference node for NPN operation; connected to ground or low-side return path in most configurations. |
| 3 | Collector | Output current terminal; handles switched load current up to 500 mA DC with ≤50 V potential swing. |
Key Features
| Feature | Design Value |
|---|---|
| High DC current capability | 500 mA continuous collector current enables direct driving of LEDs, small relays, and logic-level loads. |
| Low VCEsat | 600 mV max reduces power loss and heat generation in battery-operated portable equipment. |
| Tight hFE binning (AS) | 170–340 gain range simplifies base resistor calculation and improves circuit predictability across manufacturing batches. |
| Small-outline SOT323 package | 1.35 × 1.15 mm footprint saves PCB area in compact consumer electronics and wearable devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN general-purpose transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BS,115 | Same SOT323 package; hFE = 200–450 @ 10 mA, lower IC (100 mA) and VCEO (45 V). | Better suited for low-current signal amplification; not recommended for >200 mA switching loads. | Select when gain consistency at microamp bias matters more than power handling. |
| MMBT2222ALT1G | SOT-23 package; higher IC (600 mA), VCEO (40 V), but larger footprint and 200–300 hFE bin. | Compatible for higher-current loads but requires PCB redesign due to different pinout and pad layout. | Choose only if existing design accommodates SOT-23 and needs marginally higher current capability. |
Compared with BC847BS,115 and MMBT2222ALT1G, the 2PD1820AS,115 uniquely balances 500 mA current capacity, 50 V breakdown, and tight 170–340 hFE in the smallest SOT323 outline - making it optimal for space-constrained portable gear where both drive strength and gain predictability are required.

FAQ
What is the maximum continuous collector current for 2PD1820AS,115?
The maximum continuous DC collector current is 500 mA, specified at Tamb ≤ 25 °C on FR4 PCB. Derating applies above 25 °C ambient per the 625 K/W thermal resistance; at 70 °C ambient, usable IC drops to approximately 320 mA to maintain Tj ≤ 150 °C.
Is 2PD1820AS,115 pin-compatible with other SOT323 NPN transistors?
Yes - it uses standard SOT323 pinout: Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector. This matches industry-standard orientation for SC-70 packages, enabling direct replacement with other SOT323 NPN transistors like BC847 series, provided electrical parameters meet design requirements.
What does the 'AS' suffix indicate in 2PD1820AS,115?
The 'AS' denotes the hFE gain bin: 170–340 at IC = 150 mA and VCE = 10 V. Other variants include 'AQ' (85–170) and 'AR' (120–240). The '115' suffix indicates tape-and-reel packaging per JEDEC standard, 3,000 units per reel.
Can 2PD1820AS,115 be used in linear amplifier configurations?
Yes - its 150 MHz fT, 15 pF Cc, and stable hFE make it suitable for Class-A audio preamplifiers and low-noise signal conditioning up to ~100 kHz. For best linearity, operate at IC = 1–10 mA with emitter degeneration and avoid saturation by maintaining VCE > 1 V.
