onsemi MPSA92RLRAG

Overview

MPSA92RLRAG from onsemi is a PNP silicon high-voltage general-purpose transistor in TO-92 package, rated for −300 V_CEO, −300 V_CBO, −5 V_EBO, −500 mA continuous collector current, and 625 mW power dissipation at 25°C ambient. It serves as a high-voltage switching or amplification element in flyback snubbers, relay drivers, and HV bias networks.

For engineers reviewing the MPSA92RLRAG datasheet, pinout, applications, or equivalent options, key selection criteria include verified −300 V breakdown ratings, h_FE ≥ 25 at −1.0 mA, V_CE(sat) ≤ −0.5 V at −20 mA/−2 mA drive, C_cb = 6.0 pF, and TO-92 mechanical compatibility with legacy through-hole layouts.

Technical Context

The MPSA92RLRAG operates as a discrete PNP bipolar junction transistor optimized for high-voltage linear and switching applications up to 300 V. Its design emphasizes robust off-state blocking (V_(BR)CEO = −300 V, V_(BR)CBO = −300 V) and stable DC gain (h_FE = 25–100 across −1 to −30 mA), with thermal resistance R_JA = 200°C/W enabling operation from −55°C to +150°C junction temperature.

It features low base-emitter saturation voltage (V_BE(sat) ≤ −0.9 V at −20 mA/−2 mA) and moderate small-signal bandwidth (f_T = 50 MHz), supporting fast turn-off in HV switch-mode circuits while maintaining predictable gain in analog biasing stages.

FAQ

What is the maximum collector-emitter voltage rating for MPSA92RLRAG?

The MPSA92RLRAG has a guaranteed minimum collector-emitter breakdown voltage V_(BR)CEO of −300 V at I_C = −1.0 mA and I_B = 0. This rating is validated per onsemi's official datasheet (Publication Order Number: MPSA92/D, Rev. 6) and supports operation in circuits with up to 264 VAC input-derived rails plus safety margin. The MPSA92RLRAG must not be operated beyond this absolute maximum rating to prevent avalanche-induced failure.

Is MPSA92RLRAG RoHS compliant and what does the 'G' suffix indicate?

Yes, MPSA92RLRAG is RoHS compliant. The 'G' suffix in the part number explicitly denotes Pb-free (lead-free) packaging per onsemi's standard marking convention. As confirmed in the Ordering Information table on page 3 of the MPSA92/D datasheet, MPSA92RLRAG is shipped in Pb-free TO-92 tape-and-reel packaging with 2000 units per reel, meeting JEDEC J-STD-609 Category 1 requirements.

What is the DC current gain (h_FE) range for MPSA92RLRAG at typical operating conditions?

The MPSA92RLRAG exhibits h_FE ≥ 25 at I_C = −1.0 mA and V_CE = −10 V, h_FE ≥ 25 at I_C = −10 mA, and h_FE ≥ 25 at I_C = −30 mA - all measured at T_A = 25°C. These values are specified in the Electrical Characteristics table of the official MPSA92/D datasheet and define the minimum usable gain across its intended linear and switching operating range.

Can MPSA92RLRAG replace MPSA92G in existing designs?

Yes, MPSA92RLRAG is a direct functional and mechanical replacement for MPSA92G. Both share identical TO-92 package dimensions, pinout (Emitter–Collector–Base), and core electrical specifications including −300 V_CEO, −500 mA I_C, and matching h_FE minima. The only difference is packaging format: MPSA92G is supplied in bulk boxes (5000 units), while MPSA92RLRAG is tape-and-reel (2000 units) and Pb-free.

What is the thermal resistance junction-to-ambient (R_JA) for MPSA92RLRAG?

The thermal resistance junction-to-ambient (R_JA) for MPSA92RLRAG is 200°C/W under standard PCB mounting conditions (single-layer board, 1 in² copper pad). This value is specified in the Thermal Characteristics table of the MPSA92/D datasheet and determines the allowable power dissipation before exceeding the +150°C maximum junction temperature. Derating is required above 25°C ambient at 5.0 mW/°C.
