onsemi MPS8098RLRAG

Overview

MPS8098RLRAG from onsemi is an NPN general-purpose amplifier transistor in TO-92 package, rated for 60 V_CEO, 500 mA continuous collector current, and 625 mW power dissipation at T_A = 25°C. It delivers h_FE ≥ 100 at I_C = 1.0 mA and V_CE = 5 V, with f_T = 150 MHz, supporting linear amplification and switching in low-voltage analog signal paths.

For engineers reviewing the MPS8098RLRAG datasheet, pinout, applications, or equivalent options, key selection criteria include its 60 V breakdown rating, TO-92 leaded package compatibility with through-hole prototyping and legacy industrial controls, Pb-free tape-and-reel packaging (2,000 units), and verified DC gain stability across −55°C to +150°C junction temperature range.

Technical Context

This NPN bipolar junction transistor operates in active, saturation, and cutoff regions with defined safe operating area (SOA) limits up to 40 V and 200 mA under pulsed conditions. Its base-emitter turn-on voltage ranges from 0.5 V to 0.8 V depending on collector current, and V_CE(sat) remains ≤ 0.4 V at I_C = 100 mA / I_B = 5 mA.

Thermal resistance is specified as R_JA = 200°C/W (PCB-mounted) and R_JC = 83.3°C/W, enabling thermal design validation for ambient temperatures up to +70°C in sealed enclosures. Small-signal parameters include C_ibo = 25 pF and C_obo = 6.0 pF at V_CB = 5 V, supporting RF-coupled preamplifier stages up to ~100 MHz.

FAQ

What is the maximum junction temperature rating for MPS8098RLRAG?

The MPS8098RLRAG has a specified operating and storage junction temperature range of −55°C to +150°C. This allows reliable operation in harsh environments such as automotive under-hood modules or industrial motor drives where ambient temperatures exceed 85°C, provided thermal design respects the R_JA = 200°C/W limit and appropriate PCB copper area is used.

Is MPS8098RLRAG pin-compatible with other TO-92 NPN transistors like BC547 or 2N3904?

MPS8098RLRAG uses the standard TO-92 Style 1 pinout (Emitter–Base–Collector on pins 1–2–3), matching BC547 and 2N3904. However, electrical differences-including higher V_CEO (60 V vs. 45 V/40 V) and distinct h_FE vs. I_C curves-require circuit validation before substitution. The MPS8098RLRAG is not a drop-in replacement without reviewing biasing and SOA margins.

Does MPS8098RLRAG support switching applications at frequencies above 1 MHz?

Yes, the MPS8098RLRAG achieves f_T = 150 MHz and exhibits measured switching times (t_r, t_f) below 10 ns under defined test conditions (V_CC = 40 V, I_C/I_B = 10). This supports clean edge transitions in PWM-driven loads up to ~1–2 MHz, though layout parasitics and drive strength must be optimized to realize full bandwidth potential in the MPS8098RLRAG.

What does the 'G' suffix in MPS8098RLRAG indicate?

The 'G' suffix in MPS8098RLRAG denotes Pb-free (lead-free) construction per JEDEC J-STD-609, confirmed in the ordering table and thermal characteristics section. It also indicates compliance with RoHS Directive 2011/65/EU and reflects onsemi's Pb-free packaging standard for TO-92 devices shipped in tape-and-reel format (2,000 units/reel).

How does the DC current gain (h_FE) of MPS8098RLRAG vary with collector current?

The MPS8098RLRAG datasheet specifies h_FE ≥ 100 at I_C = 1.0 mA, ≥ 100 at I_C = 10 mA, and ≥ 75 at I_C = 100 mA (all at V_CE = 5 V). This demonstrates stable gain across three decades of collector current, making the MPS8098RLRAG suitable for both low-current bias networks and medium-power switching where predictable base drive is essential.
