Data Sheets:
This popular Transient Voltage Suppressor (TVS) series for 1N5629 thru 1N5665A are JEDEC registered selections for unidirectional devices. All have the same high Peak Pulse Power rating of 1500 W with extremely fast response times. They are also available in military qualified selections as described in the Features section herein. They are most often used for protecting against transients from inductive switching environments, induced RF effects, or induced secondary lightning effects as found in lower surge levels of IEC61000-4-5. They are also very successful in protecting airborne avionics and electrical systems. Since their response time is virtually instantaneous, they can also protect from ESD and EFT per IEC61000-4-2 and IEC61000-4-4.
- Unidirectional TVS series for thru-hole mounting
- Suppresses transients up to 1500 watts @ 10/1000 µs (see Figure 1)
- Clamps transient in less than 100 pico seconds
- Working voltage (VWM) range 5 V to 171 V
- Hermetic sealed DO-13 metal package
- JAN/TX/TXV military qualifications also available for the tighter tolerance “A” suffix devices per MIL-PRF-19500/500 by adding the JAN, JANTX, or JANTXV prefix, e.g. JANTXV1N5629A, etc.
- For bidirectional TVS in the same DO-13 package, see separate data sheet for the 1N6036 – 1N6072A series (also military qualified)
- Surface mount equivalent packages also available as MSMC 5.0A - MSMC 170CA in separate data sheet (consult factory for other surface mount options)
- Plastic axial-leaded equivalents available in the 1N6267 – 1N6303A series in separate data sheet
- ESD & EFT protection per IEC 61000-4-2 and -4-4
- Inherently radiation hard per Microchip MicroNote 050
