Both the base resistor (R1) and the emitter-base resistor (R2) are 22 kOhms, giving a matched switching threshold across the complementary pair. With a collector-emitter breakdown of 50 V and a maximum collector current of 100 mA per transistor, this part suits low-power inverting and level-shifting stages where board area is tight. ## Transition frequency and saturation A transition frequency of 250 MHz means the IMD2AT108 can handle switching up into the low-VHF range, adequate for most digital interface translation and oscillator circuits. The Vce saturation is specified at 300 mV maximum with a 500 µA base drive and 10 mA collector current, which keeps the on-state voltage drop low enough for 3.3 V logic rails. Minimum DC current gain is 56 at 5 mA collector current and 5 V Vce. ## Active product status This is a current-production part, ROHS3 compliant, available through independent distribution.","metaTitle":"IMD2AT108 NPN/PNP Pre-Biased Dual Transistor, 250 MHz","metaDescription":"IMD2AT108 dual pre-biased transistor: one NPN, one PNP, 22 kOhm resistors, 250 MHz transition frequency, 300 mW max, SC-74/SOT-457.

The UMG1NTR is a functional peer with the same 22 kOhm resistors and 250 MHz transition frequency, but it is a dual NPN configuration, not a complementary NPN/PNP pair. Verify the circuit topology before substituting."},{"question":"What is the difference between IMD2AT108 and DTC114?","answer":"The IMD2AT108 is a dual complementary pair (one NPN, one PNP) with 22 kOhm resistors. The DTC114 is a single NPN pre-biased transistor with a different resistor network — typically 10 kOhm base and 10 kOhm emitter-base. They are not pin-compatible or functionally interchangeable without board-level changes."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/rohm/IMD2AT108","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/rohm/IMD2AT108 when reusing this data.
