500 WATT LOW CAPACITANCE
TRANSIENT VOLTAGE SUPPRESSOR
DESCRIPTION
The HSMBJSAC transient voltage suppressor (TVS) series rated at 500
Watts provides an added rectifier element as shown in Figure 4 to achieve
low capacitance in applications for data or signal lines. The low capacitance
rating of less than 30 pF may be used for protecting higher frequency
applications in inductive switching environments or electrical systems
involving secondary lightning effects per IEC61000-4-5 as well as
RTCA/DO-160D or ARINC 429 for airborne avionics. If bidirectional
protection is needed, two HSMBJSAC devices in anti-parallel configuration
are required as shown in Figure 6. With their very fast response time, they
also provide ESD and EFT protection per IEC61000-4-2 and IEC61000-4-4
respectively.
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com

Class 2: HSMBJSAC5.0 to HSMBJSAC15
Class 3: HSMBJSAC5.0 to HSMBJSAC7.0
MAXIMUM RATINGS
• Peak Pulse Power Dissipation at 25oC: 500 Watts @
10/1000 µs with repetition rate of 0.01% or less*
• Steady State Power Dissipation* at TL = +75oC: 2.5
Watts.
• Clamping Speed (0 volts to V(BR) Min.) less than 5
nanoseconds.
• Operating and Storage Temperature: -65oC to +150oC.
MECHANICAL AND PACKAGING
• CASE: Void Free Transfer Molded Thermosetting Plastic
(see DO-214AA dimensions and notes)
• FINISH: All External Surfaces Are Corrosion Resistant and
Leads Solderable
• POLARITY: Cathode (TVS) Marked with Band
• MARKING: Part number without HSMBJ prefix (ie. SAC5.0)
• WEIGHT: 0.1 Grams (Approx.)
* TVS devices are not typically used for dc power dissipation and are instead operated < VWM (rated standoff voltage) except for transients
that briefly drive the device into avalanche breakdown (VBR to VC region) of the TVS element. Also see Figures 5 and 6 for further
protection details in rated peak pulse power for unidirectional and bidirectional configurations respectively.

Clamping Factor: The ratio of the numerical value of VC to V(BR) is typically 1.4 @ full rated power, 1.20 @ 50% rated power. Also see MicroNote 108.
Note 1: A transient voltage suppressor is normally selected according to voltage (VWM), that should be equal to or greater than the dc or continuous
peak operating voltage level.
Note 2: When pulse testing, test in TVS avalanche direction. Do not pulse in “forward” direction. See section for “Schematic Applications” herein.
