What are the key features of PEMH9?
- Dual NPN/PNP resistor-equipped transistor (RET) pair in a single 6-pin SOT-666 package reduces component count and PCB area
- Built-in bias resistor ratio of 4.7 eliminates the need for discrete external base resistors, simplifying circuit design
- Rated for 100 mA collector current and 50 V collector-emitter voltage with DC current gain (hFE) of at least 100
- Operates up to 100 MHz transition frequency, suitable for switching and signal amplification in high-frequency digital circuits
What is PEMH9 used for?
The PEMH9 is designed for digital switching applications in consumer electronics, portable devices, and industrial control logic where a complementary NPN/PNP transistor pair with integrated bias resistors is needed. The built-in resistor ratio of 4.7 simplifies I/O interface circuits, LED driver stages, and logic level translators without requiring separate discrete resistors. Its 6-pin SOT-666 package enables very compact dual-transistor implementations in space-constrained PCBs such as mobile phone accessories and wearable devices.

Frequently Asked Questions
What are the key electrical ratings of the PEMH9 dual digital transistor?
The PEMH9 is rated for a maximum collector current of 100 mA, collector-emitter voltage of 50 V, and a minimum DC current gain (hFE) of 100. Its transition frequency reaches 100 MHz, enabling use in both low-frequency switching and moderate-speed digital signal applications.
Why does the PEMH9 include built-in bias resistors and what is the resistor ratio?
The PEMH9 integrates bias resistors with a ratio of 4.7 (R1/R2) directly into the transistor package. This eliminates the need for external base resistors in digital switching circuits, saving board space and reducing component count by at least 2 discrete resistors per transistor, which is especially valuable in high-density PCB designs.
What is the package type of PEMH9 and how does its footprint compare to discrete transistors?
The PEMH9 comes in a 6-pin SOT-666 flat lead package, which measures approximately 1.6 mm x 1.6 mm. This is significantly smaller than mounting two discrete SOT-23 transistors plus separate resistors, making it ideal for ultra-compact PCB layouts in wearable electronics, mobile accessories, and IoT devices.
Which circuit applications are best served by the PEMH9 complementary NPN/PNP pair?
The PEMH9 is well-suited for complementary switching circuits such as push-pull output stages, H-bridge motor drivers handling currents up to 100 mA, and logic interface circuits requiring both NPN and PNP control elements. Its 50 V collector-emitter rating also supports use in small relay driver circuits operating from 12 V to 48 V supply rails.
