Product details

Overview

2SB1468R from SANYO is a PNP epitaxial planar silicon power transistor in TO-220ML package, rated for –30 V V_CEO, –8 A I_C, and 2.5 W P_C at T_c = 25°C, with V_CE(sat) ≤ –0.5 V at I_C = –5 A and I_B = –0.25 A, used in high-speed relay drivers and DC-DC converter switching stages.

For engineers reviewing the 2SB1468R datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed h_FE ≥ 70 at I_C = –1 A, f_T = 12 MHz, low saturation voltage under pulsed 12 A load, and micaless TO-220ML thermal design compatibility.

Technical Context

This device operates as a medium-power PNP switching transistor with fixed-emitter configuration, optimized for fast turn-on/turn-off (t_on ≤ 2.0 µs, t_off ≤ 5.0 µs) and robust pulsed current handling up to –20 A I_CP. Its h_FE classification (Group 1: h_FE = 70–140 at V_CE = –2 V, I_C = –1 A) ensures consistent gain across production lots.

The TO-220ML package provides direct-mount thermal path without mica insulation, enabling efficient heat transfer to heatsinks. Absolute maximum ratings are defined at T_c = 25°C, with derating applied above 25°C ambient per the PC–Ta curve (2.5 W at 25°C, 0 W at 150°C).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	–30 V - Maximum collector-to-emitter voltage before breakdown in open-base condition.
I_C	–8 A - Continuous DC collector current rating at T_c = 25°C.
V_CE(sat)	≤ –0.5 V - Ensures minimal conduction loss at I_C = –5 A, I_B = –0.25 A (IC/IB = 20).
h_FE	70–140 - DC current gain range at V_CE = –2 V, I_C = –1 A, defining base drive sizing.
f_T	12 MHz - Transition frequency confirming suitability for high-speed switching up to ~1–2 MHz operation.
P_C	2.5 W - Maximum collector dissipation at case temperature 25°C; requires heatsink for >1 W continuous use.
t_on/t_off	≤ 2.0 / ≤ 5.0 µs - Fast switching times reduce power loss during transitions in PWM circuits.

Pinout & Package

2SB1468R is housed in a micaless TO-220ML package (SANYO designation), featuring a metal tab electrically connected to the collector for direct heatsink mounting and simplified thermal management.

Pin/Terminal	Circuit Role	Design Meaning
1 (Base)	Control input	Receives negative base current to saturate the PNP transistor; requires current-limiting resistor.
2 (Collector)	Power output node	Connected to metal tab and heatsink; carries full load current; must be isolated from other potentials if heatsink is grounded.
3 (Emitter)	Reference terminal	Typically tied to positive rail in high-side switch configurations; defines common reference for base drive.

Key Features

Feature	Design Value
Micaless TO-220ML package	Eliminates insulating washer, reducing thermal resistance by ~1.5°C/W and simplifying mechanical assembly.
Low V_CE(sat)	–0.5 V max at I_C = –5 A enables <1.5 W conduction loss in 12 V relay driver applications.
High pulsed current capability	Rated I_CP = –20 A supports short-duration surge loads in motor commutation or inverter leg switching.
Guaranteed h_FE binning	Group 1 (70–140) ensures predictable base drive requirements across production batches.
Fast switching performance	t_on ≤ 2.0 µs and t_off ≤ 5.0 µs minimize overlap loss in complementary BJT half-bridge designs.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
2SB1260-Z	V_CEO = –20 V, I_C = –5 A, TO-220 package with insulated tab.	Limited to lower-voltage systems; requires mica insulator for heatsink isolation.	Select when operating below 16 V and board space allows added insulation layer.
MJD2955T4	V_CEO = –60 V, I_C = –10 A, TO-220AB package, higher V_CEO but slower t_off (10 µs).	Better voltage margin for 48 V systems; less suitable for >200 kHz switching due to longer turn-off.	Prefer for industrial 48 V DC bus applications where voltage headroom outweighs speed needs.

Compared with 2SB1468R, 2SB1260-Z trades voltage/current headroom for cost-sensitive 12 V relay use, while MJD2955T4 extends voltage capability at the expense of switching speed-making 2SB1468R optimal for 24 V, medium-frequency switching where thermal efficiency and timing symmetry matter.

FAQ

What is the absolute maximum collector-emitter voltage rating for the 2SB1468R?

The 2SB1468R has an absolute maximum V_CEO rating of –30 V at T_a = 25°C. This rating applies with the base open and defines the upper limit before avalanche breakdown occurs. Operation beyond this voltage-even momentarily-may cause irreversible damage. Derating is required at elevated temperatures per the datasheet's absolute maximum ratings table.

Does the 2SB1468R have a built-in base-emitter resistor?

No, the 2SB1468R is a standard bipolar junction transistor without any integrated base-emitter resistors. It requires external base drive circuitry-including a current-limiting resistor-to establish proper bias conditions. The device's h_FE binning (70–140) means base current must be sized accordingly for target collector current and saturation voltage.

Is the metal tab on the 2SB1468R electrically isolated?

No, the metal tab on the 2SB1468R is internally connected to the collector terminal (Pin 2). Because it uses a micaless TO-220ML package, the tab is not insulated and must be electrically isolated from the heatsink using a non-conductive mounting kit if the heatsink is referenced to a different potential than the collector.

What is the typical DC current gain (h_FE) of the 2SB1468R at I_C = –1 A?

The 2SB1468R is binned into Group 1 with h_FE = 70–140 when measured at V_CE = –2 V and I_C = –1 A. This range ensures predictable base drive requirements across units and supports stable operation in linear or saturated switching modes without excessive base current variation.

Can the 2SB1468R be used in parallel with another 2SB1468R for higher current handling?

Parallel operation of 2SB1468R devices is not recommended without individual emitter resistors and matched h_FE bins. Due to inherent parameter spread (especially V_BE and h_FE), unequal current sharing may occur, leading to thermal runaway. For >8 A continuous loads, use a single higher-rated device or consult SANYO's application notes on forced current balancing.
