Product details

Overview

KSH210TM from Fairchild Semiconductor is a PNP epitaxial silicon power transistor in D-PAK surface-mount package, rated for -25 V V_CEO, -5 A continuous collector current, 12.5 W collector dissipation at T_C = 25°C, and DC current gain (h_FE) of 70–180 at I_C = -500 mA, used in high-current linear regulation and switching circuits in industrial motor drives.

For engineers reviewing the KSH210TM datasheet, pinout, applications, or equivalent options, key selection criteria include verified PNP polarity, confirmed -5 A DC rating, validated D-PAK thermal performance, and documented V_CE(sat) ≤ -0.75 V at I_C = -2 A / I_B = -200 mA for low-loss switching operation.

Technical Context

The KSH210TM operates as a medium-power PNP bipolar junction transistor with epitaxial base construction enabling stable h_FE across collector currents from -50 mA to -5 A. Its safe operating area (SOA) is defined up to 5 ms pulse width with V_CC = -30 V and I_C = 10I_B, supporting robust transient handling in inductive load switching.

Thermal derating begins at T_C = 25°C, with linear reduction to zero dissipation at T_C = 175°C. Output capacitance (C_ob) is 120 pF at V_CB = -10 V, f = 0.1 MHz, supporting predictable turn-off timing in hard-switched topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	-25 V - Maximum sustainable collector-emitter voltage under open-base condition; defines breakdown margin in switching applications.
I_C (DC)	-5 A - Continuous collector current rating at T_C = 25°C; sets maximum steady-state load current capability.
P_C (T_C = 25°C)	12.5 W - Maximum power dissipation with case temperature held at 25°C; determines heatsink sizing baseline.
h_FE	70–180 - DC current gain range at V_CE = -1 V; enables predictable base drive design across operating points.
V_CE(sat)	-0.75 V @ I_C = -2 A, I_B = -200 mA - Low saturation voltage ensures <1.5 W conduction loss at rated current.
f_T	65 MHz - Current gain bandwidth product at V_CE = -10 V, I_C = -100 mA; supports moderate-frequency switching up to ~5–10 MHz.
C_ob	120 pF @ V_CB = -10 V - Output junction capacitance; directly impacts turn-off energy and snubber design.

Pinout & Package

D-PAK (TO-252) surface-mount package with exposed drain pad for thermal enhancement; dimensions: 9.50 × 6.10 × 2.70 mm (L × W × H), lead pitch 5.34 mm.

Pin/Terminal	Circuit Role	Design Meaning
1 - Base	Control electrode	Receives negative base current to enable conduction; requires current-limited drive due to I_B max = -1 A rating.
2 - Collector	High-side current path	Connected to positive rail in PNP high-side switch configuration; electrically tied to exposed thermal pad.
3 - Emitter	Reference terminal	Typically connected to load supply rail; serves as common return for base drive and collector current.

Key Features

Feature	Design Value
High DC current gain	h_FE ≥ 70 at I_C = -500 mA - Reduces required base drive power and simplifies driver stage design.
Low V_CE(sat)	-0.75 V @ I_C = -2 A - Limits conduction loss to ≤1.5 W, improving thermal efficiency in linear and saturated operation.
D-PAK thermal performance	12.5 W P_C at T_C = 25°C - Enables compact PCB layout with minimal heatsinking for ≤5 A loads.
Surface-mount compatibility	Lead-formed D-PAK footprint - Supports automated reflow assembly without lead bending; no through-hole requirement.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP power transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJD2955G	V_CEO = -60 V, I_C = -10 A, P_C = 15 W, h_FE min = 20 @ I_C = -4 A - higher voltage/current ratings but lower gain consistency.	Supports higher bus voltages (≤60 V) and heavier loads; less suitable for precision gain-dependent linear regulation.	Select MJD2955G when system requires >25 V headroom or >5 A peak current; verify SOA compliance at elevated T_C.
PN2907A	V_CEO = -60 V, I_C = -600 mA, P_C = 625 mW, h_FE min = 100 - much lower power, TO-92 packaged, not surface-mount.	Limited to low-power signal switching or biasing; incompatible with >1 A load or automated SMT assembly.	Choose PN2907A only for prototyping or low-current auxiliary functions; not a functional replacement for KSH210TM's power handling.

Compared with MJD2955G and PN2907A, the KSH210TM uniquely balances -5 A DC current, -25 V rating, D-PAK mountability, and h_FE ≥70 at mid-current - making it optimal for space-constrained industrial switching where thermal density and gain predictability matter more than extreme voltage margin or ultra-low cost.

FAQ

What is the maximum continuous collector current rating for the KSH210TM?

The KSH210TM is rated for -5 A continuous collector current (I_C) at case temperature T_C = 25°C. This rating assumes adequate heatsinking; derating applies above 25°C per the published power derating curve, reaching zero dissipation at T_C = 175°C. The KSH210TM must not exceed this limit in DC or repetitive pulse operation without thermal verification.

Does the KSH210TM have a built-in diode or integrated protection features?

No, the KSH210TM is a discrete PNP bipolar junction transistor with no integrated diode, protection circuitry, or thermal shutdown. It contains only the three-terminal BJT structure - base, collector, emitter - as confirmed in the Fairchild Rev. A4 datasheet. External flyback diodes, base resistors, and current-limiting components must be added per application requirements. The KSH210TM relies entirely on external design for safe operation.

What package type does the KSH210TM use, and is it RoHS-compliant?

The KSH210TM uses the D-PAK (TO-252) surface-mount package with lead-formed terminals, as specified in the Fairchild datasheet. While the original Rev. A4 document predates RoHS enforcement, current production lots supplied by Aetrix Electronics meet RoHS Directive 2011/65/EU and are lead-free. The KSH210TM's package markings and material declarations align with JEDEC standard MS-012.

Can the KSH210TM be used in avalanche mode?

No, the KSH210TM is not rated or characterized for avalanche operation. Its absolute maximum V_CEO = -25 V and V_CBO = -40 V define hard breakdown limits, and the datasheet provides no SOA curves, energy ratings, or test conditions for repetitive avalanche. Using the KSH210TM beyond V_CEO risks permanent degradation. For avalanche-tolerant designs, consider purpose-built parts such as the FZT795 or NSS12201LT1G instead of the KSH210TM.

What is the typical V_BE(on) for the KSH210TM at I_C = -2 A?

The typical base-emitter on voltage (V_BE(on)) for the KSH210TM is -1.6 V at V_CE = -1 V and I_C = -2 A, as specified in the "Electrical Characteristics" table of the Fairchild datasheet. This value reflects forward-biased junction behavior under active conduction and is critical for calculating required base drive voltage and series resistor values in practical circuits using the KSH210TM.
