onsemi MPS6717RLRA

Overview

MPS6717RLRA from onsemi is an NPN silicon general-purpose amplifier transistor in TO-92 package, rated for 1.0 W total device dissipation at T_A = 25°C, V_CEO = 80 V, I_C = 500 mA, and h_FE = 80–250 (at I_C = 50–250 mA). It serves as a medium-power linear or switching gain stage in low-frequency audio and power control circuits.

For engineers reviewing the MPS6717RLRA datasheet, pinout, applications, or equivalent options, key selection criteria include its 80 V V_CEO, 1.0 W ambient-rated power handling, TO-92 thermal resistance (R_JA = 125°C/W), DC current gain range, and tape-and-reel packaging for automated assembly.

Technical Context

The MPS6717RLRA operates as a single NPN bipolar junction transistor optimized for linear amplification and saturated switching up to ~100 MHz f_T. Its safe operating area (SOA) supports pulsed collector currents up to 500 mA with defined thermal and second-breakdown limits, and it maintains stable h_FE across −55°C to +150°C junction temperature.

Electrical behavior is characterized by V_CE(sat) ≤ 0.5 V at I_C/I_B = 25, V_BE(on) ≤ 1.2 V at I_C = 250 mA, C_cb ≤ 30 pF at 10 V, and small-signal h_fe = 2.5–25 at 20 MHz - confirming suitability for low-to-mid frequency analog and switching applications without RF optimization.

FAQ

What is the maximum continuous collector current rating for the MPS6717RLRA?

The MPS6717RLRA has a maximum continuous collector current (I_C) rating of 500 mA at T_A = 25°C. This value decreases with rising ambient temperature due to thermal derating (8 mW/°C above 25°C), and actual usable current depends on PCB copper area, airflow, and heatsinking. The MPS6717RLRA must not exceed this limit in DC or high-duty-cycle pulse applications to avoid thermal runaway or permanent damage.

Does the MPS6717RLRA support Pb-free soldering processes?

Yes, the MPS6717RLRA is a Pb-free device compliant with RoHS directives. Its marking includes the "G" suffix and/or microdot indicator per onsemi's Pb-free packaging standard. The MPS6717RLRA supports standard lead-free reflow profiles (J-STD-020) and is qualified for both wave and hand-soldering using Pb-free alloys, with no special pre-conditioning required beyond standard moisture sensitivity level (MSL) handling.

What is the typical DC current gain (h_FE) of the MPS6717RLRA at 250 mA collector current?

At I_C = 250 mA and V_CE = 1.0 V, the MPS6717RLRA exhibits a minimum h_FE of 50 and a typical value near 100–150, based on the datasheet's h_FE vs. I_C curve at 25°C. The MPS6717RLRA's gain remains usable down to −55°C and up to +125°C, though it decreases gradually at temperature extremes - design margins should account for this variation in precision bias networks.

Can the MPS6717RLRA be used as a direct replacement for the 2N2222A in existing designs?

The MPS6717RLRA shares the same TO-92 package and pinout (Emitter-Base-Collector, Pin 1–2–3), but it is not a direct replacement for the 2N2222A due to its higher V_CEO (80 V vs. 40 V) and doubled power rating (1.0 W vs. 0.5 W). While electrically compatible in low-voltage circuits, the MPS6717RLRA may require updated thermal analysis and biasing verification in legacy 2N2222A designs to leverage its enhanced ratings safely.

What is the thermal resistance junction-to-ambient (R_JA) for the MPS6717RLRA in standard PCB mounting?

The MPS6717RLRA has a specified R_JA of 125°C/W under standard JEDEC test conditions (single-layer 1 in² copper pad, no airflow). In real-world PCB layouts with 2 oz copper, thermal vias, and adjacent ground planes, measured R_JA typically improves to 60–90°C/W. For reliable operation, ensure the MPS6717RLRA's junction temperature stays below +150°C using this R_JA value and actual power dissipation.
