Description and Introduction

Sincerity Mocroelectronics - PNP EPITAXIAL PLANAR TRANSISTOR The HMBT3906 is a PNP bipolar junction transistor (BJT) commonly used for amplification and switching applications. Below are its key specifications:  

- **Transistor Type**: PNP  
- **Maximum Collector-Base Voltage (VCBO)**: -40V  
- **Maximum Collector-Emitter Voltage (VCEO)**: -40V  
- **Maximum Emitter-Base Voltage (VEBO)**: -5V  
- **Continuous Collector Current (IC)**: -200mA  
- **Total Power Dissipation (Ptot)**: 300mW  
- **DC Current Gain (hFE)**: 100-300 (typical)  
- **Transition Frequency (fT)**: 250MHz (typical)  
- **Operating Temperature Range**: -55°C to +150°C  

The HMBT3906 is often used in complementary pairs with the NPN HMBT3904 transistor. It is available in various packages, including SOT-23 and TO-92.

Alternative Part Number

  • MMBT3906 --: Industry-standard PNP switching transistor with nearly identical Vceo, Ic, and hFE specs; widely available and pin-compatible in SOT-23.
  • 2N3906 --: Classic PNP general-purpose transistor with equivalent electrical ratings; through-hole TO-92 package, suitable when board layout allows leaded parts.
  • BC857 --: Low-power PNP transistor in SOT-23 with comparable voltage and current ratings, a common alternative for general switching and amplification.
  • PMBT3906 --: PNP general-purpose transistor matching the 3906 specifications in SOT-23, a direct functional replacement from a major supplier.
