DT

Delayed Trigger: “Total Turn-On Time” irreversibly increased to >1 μs. Required if national or international export restrictions apply (“dual use  products”). (2)

S-ON

Soft Turn-On:  “Turn-On Rise Time” increased by ~20%. Simplified EMC design and less critical wiring if the shortest possible edge steepness is not required. (3)

S-OFF

Soft Turn-Off: “Turn-Off Rise Time” increased by ~20%. Simplified EMC design and less critical wiring if the shortest possible edge steepness is not required. (3)

S-TT

TT-C

Customized Transition Time:  Customized rise & fall times to meet individual design requirements. (2)

MIN-ON

Minimum On-Time: Individually increased Minimum On-Time to ensure a minimum on duration indepently of control signal.  For safety relevant circuits.

MIN-OFF

Minimum Off-Time: Individually increased Minimum Off-Time to ensure a minimum off duration indepently of control signal. For safety relevant circuits.

ST

Stage Tapping:  Connectors at the individual stages of stack in order to utilize single power semiconductors. To achieve fast rise times also at very low operating voltages (<0.01xVo).

LNC

Low Natural Capacitance: C_N reduced by approximately 30%. To minimize capacitive power losses in applications with high switching frequency and high switching voltage (Pc= V² x C x f).

LL

Low Leakage Current: Off-state current reduced to less than 10%  of the specified value. Not available in connection with the cooling fin options and for switches of the UF series.

LN

Low Noise:  Internal power driver modified for zero noise emission for a specific period of time. Relevant in conjunction with extremely sensitive detector amplifiers (e.g. SEV/MCP applications) only. (2)

ISO-25

25 kV Isolation:  Isolation Voltage increased to  25 kVDC. Housing dimensions may change for some models.

ISO-40

40 kV Isolation:  Isolation Voltage increased to  40 kVDC. Housing dimensions may change for some models.  Only in connection with option PT-HV.

ISO-80

80 kV Isolation:  Isolation Voltage increased to  80 kVDC. Housing dimensions may change for some models.  Only in connection with option PT-HV.

ISO-120

120 kV Isolation: Isolation Voltage increased to 120 kVDC. Housing dimensions may change for some models. Only in connection with option PT-HV.

PL

Passive Lock: Special inhibit function for two single switches in fast push-pull circuits. The input of the passive switch will be locked by the activated switch to avoid turn-on by noise.

I-PC

Integrated Part Components: Integration of small part components according to customer’s specifications (e.g. buffer capacitors, snubbers, damping resistors, diodes, opto couplers). (2)
