Product details

Overview

2SB1215S-TL-H from onsemi is a PNP bipolar junction transistor rated for –100 V V_CEO, –3 A I_C, and low –150 mV typical V_CE(sat) at –1.5 A/–0.15 A, housed in a halogen-free TP-FA (SC-63/TO-252) surface-mount package. It serves as a high-current switching device in relay drivers and DC-DC converters.

For engineers reviewing the 2SB1215S-TL-H datasheet, pinout, applications, or equivalent options, key selection criteria include verified V_CE(sat) performance at 1.5 A, f_T ≥ 130 MHz, h_FE rank S (140–280), JEDEC TO-252 footprint compatibility, and Pb-free/halogen-free compliance per ordering code TL-H.

Technical Context

This PNP transistor employs epitaxial planar die construction with optimized base doping to achieve low saturation voltage and excellent h_FE linearity across collector currents from 0.1 A to 2 A. Its f_T of 130–180 MHz supports fast switching in hard-switched topologies.

The device operates within a junction temperature range of –55°C to +150°C and delivers 20 W power dissipation at T_c = 25°C. Switching times are characterized at V_CC = 50 V with defined test circuit conditions: t_on = 100 ns, t_stg = 800–900 ns, t_f = 50 ns.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	–100 V - Maximum allowable collector-emitter voltage under open-base condition; defines safe blocking capability in high-side switch configurations.
I_C	–3 A - Continuous DC collector current rating; supports sustained load switching up to 3 A without thermal derating at T_c = 25°C.
V_CE(sat)	–150 mV (typ) at I_C = –1.5 A, I_B = –0.15 A - Low conduction loss enables efficient operation in high-current linear and saturated switching modes.
f_T	130–180 MHz - Gain-bandwidth product confirming suitability for medium-frequency switching applications such as 100 kHz–500 kHz DC-DC converters.
h_FE	140–280 (Rank S) at V_CE = –5 V, I_C = –0.5 A - Tight DC current gain distribution ensures predictable base drive requirements in production designs.
t_f	50 ns - Fast fall time reduces switching transition losses and EMI generation during turn-off in pulse-width modulated circuits.

Pinout & Package

2SB1215S-TL-H uses the TP-FA package (JEDEC TO-252, JEITA SC-63), a 4-pin surface-mount outline with dual collector terminals for enhanced current handling and thermal path optimization. Package dimensions: 7.0 × 5.0 × 2.3 mm (L × W × H), mass = 0.282 g.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control terminal; accepts negative bias current to enable conduction; requires external current-limiting resistor for reliable drive.
2 & 4	Collector	Dual-collector configuration lowers effective R_DS(on)-equivalent resistance and improves thermal spreading; both pins must be connected to high-side rail.
3	Emitter	Common emitter node; connects to load return or ground reference; carries full load current and must be routed with adequate copper area.

Key Features

Feature	Design Value
Low V_CE(sat)	–150 mV typical at –1.5 A enables <150 mW conduction loss per device, reducing heatsink requirements in space-constrained power stages.
High f_T	130–180 MHz bandwidth supports clean square-wave switching up to ~100 MHz edge rates, minimizing ringing in gate-drive and signal-path applications.
Rank S h_FE binning	140–280 h_FE range ensures consistent base drive design across production lots, eliminating need for post-manufacture gain sorting.
Halogen-free & Pb-free	TL-H suffix certifies compliance with IEC 61249-2-21 and JEDEC J-STD-609A, meeting RoHS and automotive ELV directive requirements.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP high-current switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
2SB1215T-TL-H	Higher h_FE bin (200–400 vs. 140–280); otherwise identical electrical specs, package, and marking.	Suitable where lower base drive current is required; may reduce base resistor power dissipation in high-duty-cycle operation.	Select 2SB1215T-TL-H when designing for minimal I_B or tighter h_FE tolerance; use 2SB1215S-TL-H for cost-sensitive volume production with standard drive margins.
MJD122G	TO-252 package, –100 V V_CEO, –8 A I_C, but higher V_CE(sat) (–500 mV typ at –4 A) and no halogen-free certification.	Acceptable where higher current headroom is needed but thermal budget allows higher saturation loss; not compliant with halogen-free mandates.	Choose MJD122G only if absolute maximum I_C > 3 A is required and halogen-free compliance is not mandatory; otherwise 2SB1215S-TL-H offers superior efficiency and regulatory alignment.

Compared with 2SB1215T-TL-H, the 2SB1215S-TL-H provides lower base drive sensitivity and tighter cost control; versus MJD122G, it delivers 3.3× lower conduction loss at rated current and guaranteed halogen-free construction-critical for automotive and industrial end-equipment certifications.

FAQ

What is the maximum continuous collector current rating for the 2SB1215S-TL-H?

The 2SB1215S-TL-H is rated for –3 A continuous collector current (I_C) at case temperature T_c = 25°C. Derating applies above this temperature per the PC–T_c curve in the datasheet; at T_c = 100°C, the usable I_C drops to approximately –1.2 A. This rating assumes proper PCB copper area and thermal vias to maintain case temperature.

Does the 2SB1215S-TL-H have a halogen-free construction?

Yes, the 2SB1215S-TL-H is explicitly certified halogen-free per its TL-H suffix and complies with IEC 61249-2-21. The device uses halogen-free molding compound and leadframe plating, satisfying stringent environmental requirements for automotive and industrial end equipment.

What is the pin configuration of the 2SB1215S-TL-H TP-FA package?

The 2SB1215S-TL-H TP-FA (TO-252) package has four terminals: Pin 1 = Base, Pins 2 & 4 = Collector (dual), Pin 3 = Emitter. Both collector pins must be electrically and thermally connected to the same high-side potential; the dual-collector structure reduces effective on-resistance and improves thermal transfer to the PCB.

How does the h_FE ranking affect selection between 2SB1215S-TL-H and 2SB1215T-TL-H?

The 2SB1215S-TL-H is binned to h_FE = 140–280 at –0.5 A, while 2SB1215T-TL-H is binned to 200–400. This means 2SB1215T-TL-H requires less base current for the same collector current, improving drive efficiency-but 2SB1215S-TL-H offers tighter cost control and sufficient gain margin for most relay and converter applications.

Can the 2SB1215S-TL-H replace older through-hole PNP transistors like 2SA1015 in new designs?

The 2SB1215S-TL-H is not a direct drop-in replacement for 2SA1015 due to different package (TP-FA vs. TO-92), voltage/current ratings (–100 V/–3 A vs. –50 V/–150 mA), and pinout. However, it can serve the same functional role in modern SMT-based high-current switching designs where board space and thermal performance are prioritized over legacy footprint compatibility.
