Power Rectifiers
The rectifier is a unidirectional device which conducts when for-
ward voltage (above 0.7 V) is applied.
To connect the rectifier:
1. Connect
Anode
to
Collector Terminal (C)
.
2. Connect
Cathode
to
Emitter Terminal (E)
.
To begin testing, perform the following procedures.
Procedure 1: V
RRM
and I
RM
To measure the V
RRM
and I
RM
parameter:
1. Set
Variable Collector Supply Voltage Range
to
1500 V.
(
2000 V
on 370)
2. Set
Horizontal
knob to sufficient scale to allow viewing of
trace at the required voltage level (
100 V/DIV
for 400 V and
600 V devices and
50 V/DIV
for 200 V devices).
3. Set
Mode
to
Leakage.
4. Set
Vertical
knob to
100 μA/DIV.
(Due to leakage setting, the
CRT readout will be 100 nA per division.)
5. Set
Terminal Selector
to
Emitter Grounded-Open Base.
6. Set
Polarity
to (–).
7. Set
Power Dissipation
to
2.2 W.
(
2 W
on 370)
8. Set
Left-Right Terminal Jack Selector
to correspond with
location of test fixture.
9. Increase
Variable Collector Supply Voltage
to the rated
V
RRM
of the device and observe the dot on the CRT. Read
across horizontally from the dot to the vertical current scale.
This measured value is the leakage current.
(Figure AN1006.2)
Figure AN1006.2
I
RM
= 340 nA at V
RRM
= 600 V
Procedure 2: V
FM
Before testing, note the following:
A Kelvin test fixture is required for this test. If a Kelvin fixture is
not used, an error in measurement of VFM will result due to
voltage drop in fixture. If a Kelvin fixture is not available,
Figure AN1006.3 shows necessary information to wire a test
fixture with Kelvin connections.
Due to the current limitations of standard curve tracer
model 576, V
FM
cannot be tested at rated current without a Tek-
tronix model 176 high-current module. The procedure below is
done at I
T(RMS)
= 10 A (20 A
PK
). This test parameter allows the
use of a standard curve tracer and still provides an estimate of
whether V
FM
is within specification.
Figure AN1006.3
Instructions for Wiring Kelvin Socket
To measure the V
FM
parameter:
1. Set
Variable Collector Supply Voltage Range
to
15 Max
Peak Volts
. (
16 V
on 370)
2. Set
Horizontal
knob to
0.5 V/DIV
.
3. Set
Mode
to
Norm
.
4. Set
Vertical
knob to
2 A/DIV
.
5. Set
Power Dissipation
to
220 W
(
100 W
on 577).
6. Set
Polarity
to
(+).
7. Set
Left-Right Terminal Jack Selector
to correspond with
location of test fixture.
8. Increase
Variable Collector Supply Voltage
until current
reaches 20 A.
WARNING: Limit test time to 15 seconds maximum.
To measure V
FM
, follow along horizontal scale to the point where
the trace crosses the 20 A axis. The distance from the left-hand
side of scale to the crossing point is the V
FM
value.
(Figure AN1006.4)
Note: Model 370 current is limited to 10 A.

SOCKET
SOCKET PINS
One set of
pins wired to
Collector (C),
Base (B), and
Emitter (E)
Terminals
The pins which correspond to
the anode and cathode of the
device are wired to the terminals
marked C
SENSE
(MT2/Anode) and
E
SENSE
(MT1/Cathode). The gate
does not require a Kelvin
connection.
Socket used
must have two
sets of pins
