KAQY6N1
Dual channel 60V 200mA MOSFET SSR with 2500V isolation, SOP-8 for multi-channel DC switching.
Product Overview
Description
The KAQY6N1 is a dual-channel MOSFET output solid state relay providing two independent switching channels in one package.
Each channel supports 60V and 200mA, suitable for multi-channel DC control applications.
The SOP-8 package saves board space compared to using two single-channel SSRs.

FAE Expert Insights
"The KAQY6N1 is a specialized part I recommend for high-current industrial applications. With 1.5A capability and 60V rating, it's perfect for 24V industrial automation systems. The DIP-6 package provides good thermal performance and easy handling. I've specified this in factory automation projects where multiple loads need switching from a central controller. The unlimited switching life (vs 100K-1M for mechanical relays) is a huge advantage in high-cycling applications. Design note: at 1.5A, thermal design is critical - plan for adequate heat sinking from the start."

Frequently Asked Questions
Are the two channels isolated from each other?
The two output channels share a common connection but are isolated from the input side. The channel-to-channel isolation is typically 500-1000V. For complete channel-to-channel isolation, use two separate single-channel SSRs like KAQY212.
Channels share common - not fully isolated from each other.
Can both channels be operated simultaneously?
Yes, both channels can be turned on and off independently and simultaneously. Each channel has its own LED input, allowing complete independent control. The channels do not interfere with each other during operation.
Channels operate independently - full control flexibility.
What is the total power dissipation with both channels on?
With both channels conducting 200mA: P = 2 × (0.2² × 1.0) = 0.08W total. This low power dissipation allows both channels to operate continuously without excessive heating. The SOP-8 package handles this power level easily.
0.08W total - minimal heating even with both channels on.
Can channels be wired in parallel for higher current?
Parallel operation is not recommended due to current sharing imbalances between channels. For higher current, use a single higher-rated SSR like KAQY214 (400mA) or add external MOSFETs driven by the SSR.
Don't parallel - use higher rated SSR for more current.
What are typical applications for dual SSRs?
Common applications include: (1) Battery cell balancing switches; (2) Multi-channel I/O modules; (3) Dual polarity switching; (4) Redundant safety circuits; (5) H-bridge drivers. The dual channel saves space and reduces component count in these applications.
Ideal for multi-channel control and space-constrained designs.
