DEVICES
MLCE6.5A thru MLCE170A, e3
LEVELS
M, MA, MX, MXL
FEATURES
High reliability controlled devices with wafer fabrication and assembly lot traceability
100 % surge tested devices
Unidirectional construction. For bidirectional option see Figure 4.
Suppresses transients up to 1500 watts @10/1000s (see Figure 1)
Clamps transients in less than 100 pico seconds
Optional upscreening available by replacing the M prefix with MA, MX or MXL. These prefixes specify
various screening and conformance inspection options based on MIL-PRF-19500. Refer to MicroNote
129 for more details on the screening options.
Surface mount equivalent packages also available as MSMC(G/J)LCE6.5A - MSMC(G/J)LCE170A in
separate data sheet (consult factory for other surface mount options)
Moisture classification is Level 1 with no dry pack required per IPC/JEDEC J-STD-020B
RoHS Compliant devices
available by adding “e3” suffix
3σ lot norm screening performed on Standby Current I
D

MAXIMUM RATINGS
Peak Pulse Power dissipation at 25 C:
1500 watts at 10/1000 μs (see Figure 1) with impulse repetition
rate of 0.01% or less* at lead temperature TL of 25°C
Operating & Storage Temperatures: -65 C to +150 C
Thermal Resistance: 22 C/W junction to lead at 3/8 inch (10 mm) from body, or 82 C/W junction to
ambient when mounted on FR4 PC board with 4 mm
2 copper pads (1oz), track width 1 mm, length 25mm
Steady-State Power dissipation*: 5 watts at TL = 40 C, or 1.52 watts at TA = 25 C when mounted on
FR4 PC board described for thermal resistance
Solder Temperatures: 260
C for 10 s (maximum)
* TVS devices are not typically used for dc power dissipation and are instead operated at
≤ V
WM except for transients that briefly
drive the device into avalanche breakdown (VBR to VC region) of the TVS element. Also see Figures 3 and 4 for further protection
details in rated peak power for unidirectional and bidirectional configurations respectively.
CASE 1
1500 Watt Low Capacitance
Transient Voltage Suppressor
- High Reliability controlled devices
- Unidirectional (A) construction
- Plastic encapsulated TVS series for Thru Hole mounting
- Selections for 6.5 to 170 V standoff voltages (VWM)
