2SB676  PNP Power Darlington Transistor

TO220, übliche Anschlußbelegung B C E

Der erste Transistor hat einen internen Basis-Emitter 
Parallelwiderstand von 4,5 kOhm, die Endstufe von 300 Ohm.
Im Folgenden habe ich die PNP-typischen Minuszeichen 
weggelassen.

Maximum Ratings:

Vceo =  80 V
Vebo =   5 V

Pc = 30 W   (bis 25 grdC.)

  at Ic=3A : min 1000
Vce(sat) at Ic=3A, Ib=6mA : max 1.5 V

2SB706  PNP triple diffused transistor

Maximum Ratings:
Vcbo = 180 V
Vceo = 180 V
Vebo = 5 V
Ic = 10 A
Ic pulse 350us = 15 A
Ptot = 200 W (Junction = 25 grdC., siehe unten)
Tj = 150 grdC.
Tstg = -55 to 150 grdC.

Characteristics :
DC Current Gain at Vce=5V, Ic=2A :
  2SB706S : min 40, max 80
  2SB706R : min 60, max 120
  2SB706Q : min 100, max 200

Vce(sat) at Ic=10A, Ib=1A : typ 1.9V, max 3 V
Vbe(sat) at Ic=10A, Ib=1A : typ 2.3V, max 3 V
Transit Frequency at Vce=5V, Ic=0.2A : typ 14 MHz
Collector Base Capacitance at Vcb=10V, Ie=0, f=1MHz : 
   typ 450 pF

Das Gehäuse ist selten. So sahen später Single- In- Line 
Leistungs- ICs aus.  Wenn ich wie bei ICs links unten mit 
dem Zählen beginne, haben die Beinchen folgende Bedeutung:
Pins:
1 : Collector
2 : Basis
3 : Emitter
4 : Collector

Leider sehe ich hier nicht, ob auf der Rückseite ein Blech 
als Kontakt zum Kühlkörper frei liegt, und ob das Blech mit 
dem Collector verbunden ist, wie ich annehme. 

Leider fehlt eine Angabe des Wärmewiderstandes. Aus einem 
Diagramm: Auf ein 500 Quadratzentimeter großes Kühlblech 
geschraubt ist Ptot statt 200W nur 43 W ! und bei 100 cm2 
nur 21W.
Auch das Safe Operating Areas Diagramm relativiert die gut 
klingenden Werte: Bei Ic=2A muß wegen Second Breakdown die 
max Vce auf 80V reduziert werden

Was einen Ersatz angeht: Es hat nicht lange gedauert, den 
Typ im TO3 Gehäuse finden, von dem höchst wahrscheinlich der 
Chip stammt, der in dieses Plastikgehäuse verpflanzt wurde:
2SB600.

2SC3858   NPN Power Transistor

Gehäuse und Hersteller fehlen auf diesem Datenblatt, 
wahrscheinlich stand das nur auf dem weggeworfenen Umschlag. 
 
Complement Type: 2SA1494

Absolute Maximum Ratings:
Vcbo = Vce0 = 200V
Vebo = 6 V
Ic = 17 A
Ib = 5 A
Pc at 25grdC = 200 W
Tj = 150 grdC

Characteristics:
h FE at Vce=4V, Ic=8A : min 30
Vce sat at Ic=10A, Ib=1A : max 2.5 V
f T at Vce=12V, Ie=-1A : typ 20 MHz

Ausserdem gibt es einige winzige Bildchen. Von Interesse ist 
wohl die Kurve des Collektorstroms über der Basis- Emitter- 
Spannung: Bei 25 grdC beginnt sie bei 0,6V. Bei 0,8V gibt es 
typisch Ic=1,2A, bei 1V : 3,6A, und erst bei 2V sind es 13A. 
Für den erlaubten Spitzenstrom von 17A muß man mit 2,7V rechnen. 
Weil dann fast 1A Basistrom fließen kann, wird eine erhebliche 
Steuerleistung benötigt.
