1.5KE6.8A General Description


The Transient Voltage Suppressor (TVS) series for 1N5908 & 1N6267-1N6303A are JEDEC registered selections for unidirectional devices. The popular series of 1.5KE6.8-1.5KE400A offers similar voltages with an extended voltage range and also provides bidirectional options with a C or CA suffix. All have the same high Peak Pulse Power rating of 1500 W and extremely fast response time. They can protect from secondary lightning effects per IEC61000-4-5 and class levels described herein as well as inductive switching environments and induced RF protection. Since their response time is virtually instantaneous, they can also protect from ESD and EFT per IEC61000-4-2 and IEC61000-4-4.

1.5KE6.8A Maximum Ratings

• Peak Pulse Power dissipation at 25ºC: 1500 watts at 10/1000 s (also see Fig 1,2, and 3)
• Impulse repetition rate (duty factor): 0.01%
• tclamping (0 volts to V(BR) min.): < 100 ps theoretical for unidirectional and < 5 ns for bidirectional
• Operating and Storage temperature: -65ºC to +150ºC
• Thermal Resistance: 22ºC/W junction to lead at 3/8 inch (10 mm) from body, or 82ºC/W junction to ambient when mounted on FR4 PC board with 4 mm2 copper pads (1oz) and track width 1 mm, length 25 mm
• Steady-State Power dissipation: 5 watts at TL = 40oC, or 1.52 watts at TA = 25ºC when mounted on FR4 PC board described for thermal resistance
• Forward Surge: 200 Amps peak impulse of 8.3 ms half-sine wave at 25ºC (unidirectional only)
• Solder temperatures: 260 ºC for 10 s (maximum)

1.5KE6.8A Features

• Economical TVS series for thru-hole mounting
• Available in both Unidirectional and Bidirectional (add C or CA suffix for bi-directional)
• Voltages from 6.8 to 400 V Breakdown (VBR)
• Suppresses transients up to 1500 watts @ 10/1000 s (see Figure 1)
• Fast response
• Options for screening in accordance with MIL-PRF- 19500 for JAN, JANTX, JANTXV, and JANS are available by adding MQ, MX, MV, or MSP prefixes respectively to part numbers.
• Surface mount equivalent packages are available as SMCJ5.0 - SMCJ170CA or SMCG5.0 - SMCG170CA (consult factory for other surface mount options)
• Moisture classification is Level 1 with no dry pack required per IPC/JEDEC J-STD-020B

1.5KE6.8A Typical Application

• Protection from switching transients and induced RF
• Protection from ESD and EFT per IEC 61000-4-2 and IEC 61000-4-4
