Product details
Overview
LH1510AABTR from Vishay Semiconductors is a 1-Form-A solid-state relay (SSR) with GaAlAs LED input and dual high-reliability MOSFET output, delivering 5300 VRMS isolation, 12 Ω typical on-resistance (AC/DC config), and 200 V load voltage rating - used for bounce-free switching in telecom line cards and industrial control I/O modules.
For engineers reviewing the LH1510AABTR datasheet, LH1510AABTR pinout, LH1510AABTR application, or LH1510AABTR equivalent, this page provides verified technical context, package mapping to DIP-6, real-world switching timing (0.20 ms turn-on), safety certifications (UL 1577, VDE 0884-5), and design-meaningful parameter interpretation - all confirmed for LH1510AABTR specifically.
Technical Context
The LH1510AABTR implements optically isolated AC/DC switching via a monolithic GaAlAs LED driving two back-to-back MOSFETs, enabling bidirectional load current flow without external snubbers. Its internal architecture supports both AC and DC load configurations with distinct RON (12 Ω typ. AC/DC; 3.2 Ω typ. DC-only) and IL ratings (200 mA vs. 350 mA).
It meets reinforced insulation requirements per UL 1577 (5300 VRMS) and DIN EN 60747-5-5 (VIORM = 890 Vpeak), with creepage/clearance ≥7 mm and DTI ≥0.4 mm. Safety parameters - including PSO = 700 mW and ISI = 240 mA - are temperature-dependent and validated across −40 °C to +85 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 5300 VRMS (UL 1577, 1 min test) - enables safe separation between control logic and 200 V AC/DC loads in Class I equipment. |
| On-Resistance (AC/DC) | 12 Ω typical - limits I²R power loss to ≤120 mW at 100 mA load, reducing thermal stress in sealed enclosures. |
| Load Voltage Rating | 200 V - supports direct interface with standard AC mains-derived 120/230 VAC circuits and 100–200 VDC battery systems. |
| Turn-On Time | 0.20 ms typical - ensures fast response for programmable logic controller (PLC) output updates and ATE sequencing. |
| Off-State Leakage | <1 nA at ±100 V - prevents false triggering in high-impedance metering inputs and low-power sensor interfaces. |
| Safety Certifications | UL 1577, cUL, VDE 0884-5, FIMKO - permits use in certified industrial, medical auxiliary, and utility metering designs without additional system-level isolation. |
Pinout & Package
DIP-6 package (7.62 mm lead pitch, 9.80 mm body length), through-hole mountable with 260 °C wave-solder compatible leads. Pin 1 marked by notch and dot; leads coplanar ≤0.1 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | LED anode input | Accepts 1.4 V typical forward voltage; 50 mA absolute max - requires series resistor ≥220 Ω for 3.3 V MCU drive. |
| 2 (Cathode) | LED cathode input | Reference for opto-isolated input side; ties to MCU ground or open-drain driver sink. |
| 3 (Source 1) | MOSFET source terminal (Channel 1) | Internally connected to Channel 2 source; common node for bidirectional load return path in AC/DC config. |
| 4 (Drain 1) | MOSFET drain terminal (Channel 1) | One side of back-to-back MOSFET pair; connects to load high-side in DC-only or either AC terminal in AC/DC mode. |
| 5 (Drain 2) | MOSFET drain terminal (Channel 2) | Second drain; completes bidirectional switch path - paired with Pin 4 for full-wave AC conduction or unidirectional DC blocking. |
| 6 (Source 2) | MOSFET source terminal (Channel 2) | Electrically tied to Pin 3; forms common source node - must be referenced to load return (not input ground) for proper operation. |
Key Features
| Feature | Design Value |
|---|---|
| Clean bounce-free switching | Zero mechanical contact arcing or chatter - eliminates EMI spikes and contact wear in automatic test equipment cycling. |
| Low power consumption | 0.4 mA typical LED turn-on current - enables direct drive from ultra-low-power microcontrollers (e.g., MSP430, STM32L0) without buffer stages. |
| High reliability MOSFET output | No wear-out mechanism vs. electromechanical relays - rated for >10⁹ operations at full 200 mA load, supporting 10+ year field life. |
| Wide ambient operating range | −40 °C to +85 °C - maintains RON drift <2× and leakage <1000 nA at 200 V up to 85 °C, suitable for uncooled industrial cabinets. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar solid-state relay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay LH1510AT | DIP-6 tube-packaged variant; identical electrical specs and pinout - differs only in packaging (no tape-and-reel). | Same functional use cases; preferred for low-volume prototyping or manual assembly where reel handling is unnecessary. | Select LH1510AT when DIP-6 tube delivery aligns with SMT line constraints or small-batch production planning. |
| IXYS CPC1976Y | 400 V load rating, 35 Ω RON, 5000 VRMS isolation; uses photodiode + MOSFET architecture instead of LED-driven dual-MOSFET. | Better suited for higher-voltage HVAC controls but slower (1.5 ms turn-on); not drop-in due to higher drive current requirement (5 mA). | Choose CPC1976Y only if 400 V capability is mandatory and timing budget allows ≥1 ms switching - not a direct replacement. |
Compared with LH1510AT, LH1510AABTR offers identical performance in tape-and-reel format for automated placement; versus CPC1976Y, it trades higher voltage headroom for lower RON, faster switching, and lower drive current - making it optimal for 200 V, high-cycle industrial I/O.

FAQ
What is the maximum continuous load current for LH1510AABTR in AC/DC configuration?
The LH1510AABTR supports 200 mA continuous load current in AC/DC configuration, as specified in its absolute maximum ratings. This rating applies across the full −40 °C to +85 °C ambient range and assumes proper PCB thermal relief. Exceeding this value risks exceeding the 550 mW SSR output power dissipation limit and accelerated MOSFET degradation.
Does LH1510AABTR support DC-only load switching, and what is its RON in that mode?
Yes, LH1510AABTR supports DC-only load switching with a typical on-resistance of 3.2 Ω (1.5–3.75 Ω min–max), measured at IF = 5 mA and IL = 100 mA. This lower RON enables higher current capability (350 mA continuous) and reduced conduction loss compared to AC/DC mode - ideal for battery-powered DC control paths.
What safety certifications does LH1510AABTR hold, and how do they impact system-level compliance?
LH1510AABTR is certified to UL 1577 (5300 VRMS), cUL, DIN EN 60747-5-5 (VDE 0884-5), and FIMKO. These approvals validate its reinforced insulation barrier, allowing designers to meet IEC 61000-4-5 surge immunity and IEC 61800-5-1 functional safety requirements without adding external isolation components in many Class I industrial systems.
Can LH1510AABTR be driven directly from a 3.3 V microcontroller GPIO?
Yes - LH1510AABTR requires only 0.4 mA typical forward current to turn on, well within the 4–20 mA sourcing capability of most 3.3 V MCUs. A 2.2 kΩ series resistor limits LED current to ~1.1 mA at 3.3 V, ensuring reliable activation while staying below the 50 mA absolute maximum rating and preserving GPIO longevity.
How does the LH1510AABTR pinout differ between AC/DC and DC-only configurations?
The LH1510AABTR pinout remains identical across configurations; only external wiring changes. In AC/DC mode, Pins 4 and 5 connect to opposite ends of the load (bidirectional). In DC-only mode, Pin 4 is load (+) and Pin 5 is load (−), with Pin 3/6 forming the common source return - no internal reconfiguration is needed, simplifying PCB layout reuse.
