Product details
Overview
PMSTA06,115 from Nexperia is an AEC-Q101-qualified NPN general-purpose transistor in SOT323 (SC-70) package, rated for 80 V VCEO, 500 mA IC, and 200 mW Ptot, with DC current gain ≥50 at 10 mA and 100 mA test conditions. It serves as a switching or amplification element in compact telephony and professional communication equipment where space-constrained PCB layouts demand high reliability.
For engineers reviewing the PMSTA06,115 datasheet, PMSTA06,115 pinout, PMSTA06,115 application, or PMSTA06,115 equivalent, this discrete transistor supports automotive-grade signal switching, low-power analog amplification, and interface-level current control in FR4-mounted designs requiring thermal resistance ≤625 K/W and junction temperature up to 150 °C.
Technical Context
This NPN bipolar junction transistor operates with open-base collector-emitter voltage up to 80 V and emitter-base voltage up to 4 V, supporting linear and saturated switching modes. Its hFE remains ≥50 across two bias points (VCE = 2 V/10 mA and VCE = 1 V/100 mA), enabling stable gain in both small-signal and medium-current applications.
VCE(sat) is specified at 250 mV (IC = 100 mA, IB = 10 mA), confirming low-loss on-state performance, while fT of 100 MHz ensures usable bandwidth for audio-frequency and baseband signal handling. The device is qualified per AEC-Q101 for automotive environments but deployed primarily in professional telecom infrastructure.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Maximum safe collector-emitter voltage under open-base condition; defines upper rail limit for switching circuits. |
| IC | 500 mA - Continuous collector current rating; sets maximum load drive capability without derating. |
| hFE | ≥50 at VCE = 2 V, IC = 10 mA - Minimum DC current gain for bias stability in amplifier stages. |
| VCE(sat) | 250 mV at IC = 100 mA, IB = 10 mA - Low saturation voltage enables efficient switching with minimal power loss. |
| Ptot | 200 mW at Tamb ≤25 °C - Total power dissipation limit on FR4 PCB; determines thermal headroom in compact layouts. |
| Rth(j-a) | 625 K/W - Junction-to-ambient thermal resistance in free air; informs heatsinking requirements for sustained operation. |
Pinout & Package
SOT323 (SC-70) is a 3-pin, surface-mount plastic package measuring 2.2 mm × 1.35 mm × 0.9 mm, optimized for high-density PCB assembly and reflow soldering compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control terminal for forward-biased junction; requires current-limited drive to achieve target IC. |
| 2 | Emitter | Common reference node in common-emitter configuration; connected to ground or low-impedance return path. |
| 3 | Collector | Output terminal carrying switched or amplified current; routed to load or next stage with voltage margin ≤80 V. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical stress testing. |
| High VCEO (80 V) | Enables use in 48 V telecom systems and industrial interfaces without additional voltage clamping. |
| Very small SOT323 footprint | Reduces board area by >50% vs. SOT23; supports miniaturized handsets, line cards, and modular comms modules. |
| Low VCE(sat) (250 mV) | Minimizes conduction loss in battery-powered or thermally constrained applications such as PoE-powered endpoints. |

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 |
|---|---|---|---|
| MMBT3904LT1G | VCEO = 40 V, IC = 200 mA, hFE ≥100 at 10 mA - lower voltage/current rating, higher gain at low current. | Not suitable for 48 V+ telecom rails; limited to sub-30 V logic-level switching and low-power amplification. | Select when gain stability at <50 mA is prioritized over voltage headroom and thermal robustness. |
| BC846BW | VCEO = 65 V, IC = 100 mA, hFE ≥110 at 2 mA - narrower voltage range, lower current, higher gain at microamp bias. | Insufficient for 80 V transient suppression; best suited for sensor signal buffering and low-noise preamp stages. | Choose for precision analog front-ends where low base current and high hFE outweigh power-handling needs. |
Compared with MMBT3904LT1G and BC846BW, PMSTA06,115 delivers superior voltage margin (80 V), higher continuous current (500 mA), and automotive-grade qualification-making it uniquely suited for ruggedized telecom and industrial control applications where reliability under electrical stress is non-negotiable.

FAQ
What is the maximum junction temperature for PMSTA06,115?
The absolute maximum junction temperature (Tj) for PMSTA06,115 is 150 °C, as defined in the Absolute Maximum Ratings table. Operation above this threshold risks permanent degradation of the silicon die and bond wires, even if ambient temperature remains within specification.
Is PMSTA06,115 suitable for automotive applications?
Yes-PMSTA06,115 is explicitly qualified to AEC-Q101 standards, covering stress tests for temperature cycling, humidity, mechanical shock, and ESD. It is approved for use in automotive infotainment, telematics, and body control modules where discrete transistor reliability is critical.
How does the SOT323 package affect thermal performance?
The SOT323 package has a junction-to-ambient thermal resistance (Rth(j-a)) of 625 K/W on FR4 PCB in free air. This means a 200 mW power dissipation generates a 125 °C temperature rise above ambient-requiring careful layout, copper pour, or derating above 25 °C ambient.
What is the meaning of marking code *1G on PMSTA06,115?
The marking code *1G identifies the PMSTA06 variant on the device top surface. Per Nexperia documentation, '*' denotes manufacturing location ('t' = Malaysia), and '1G' is the type-specific identifier distinguishing PMSTA06 from PMSTA05 (*1H) in tape-and-reel packaging.
