Description

The PS331 is an integrated 3-to-1 HDMI/DVI switch designed for HDMI/DVI receiver or repeater applications. It integrates all system functions including the EDID shadow RAM, the DDC switch and Source device detection.

Each of the three HDMI/DVI input ports connect directly to an HDMI/DVI input receptacle without the need for additional components, including ESD protection. 5V tolerance is supported on the DDC and HPC interfaces. Input port selection, device control, and EDID shadow RAM loading is performed by the host through the PS331 I2C Control Interface.

Description

SS8050D331 is 25V, 1.5A, NPN Transistor. This is a general-purpose NPN bipolar junction transistor (BJT) designed for medium-current amplification and switching applications. With a relatively high collector current capability for a TO-92 package, it is widely used in driver stages, low-power switching, and signal amplification circuits.

Features

  • NPN silicon transistor
  • High collector current capability (up to 1.5A)
  • Low saturation voltage (VCE(sat))
  • Good DC current gain (hFE) characteristics
  • Compact TO-92 package
  • Suitable for switching and amplification

Absolute maximum ratings ( Ta=25°C )

1. Collector to Base Voltage: Vcbo = 40 V

2. Collector to Emitter Voltage: Vceo = 25 V

3. Emitter to Base Voltage: Vebo = 5 V

4. Collector Current: Ic = 1500 mA

5. Collector Dissipation : Pc = 1 W

6. Junction Temperature: Tj = 150°C

7. Storage Temperature: Tsg = -55 ~ +150°C

Typical Circuit Usage

  • Low-side switch (relay, LED, buzzer)
  • Signal amplification stage
  • Driver transistor for MOSFET or higher power stage
  • Audio pre-amplifier (low power)

How to Choose This Part

  • Use when moderate current (<1A practical) is required in a compact package
  • Good choice for cost-sensitive designs
  • Prefer TO-220 devices if continuous current >1A is required
  • Consider MOSFET alternatives for higher efficiency switching

Applications

  • Consumer electronics
  • Power switching circuits
  • Relay drivers
  • Embedded control systems
  • General-purpose amplification

Alternative / Equivalent Products

  • S8050 / SS8050 (generic variants)
  • 2N2222 (lower current alternative)
  • PN2222A
  • BC337
  • BD139 (higher power alternative, TO-126)
