H11G13SD Optoisolator Equivalent & Substitute Parts

Part Overview

The H11G13SD is an optoisolator with Darlington output manufactured by onsemi, featuring 5300Vrms isolation voltage and 1000% minimum current transfer ratio. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The H11G13SD operates across a temperature range of -55°C to 100°C in a 6-SMD surface mount package with gull wing leads.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the H11G13SD are evaluated based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Number of Channels: 1 (all substitutes match)
• Output Type: Darlington with Base (all substitutes match)
• Mounting Type: Surface Mount (all substitutes match)
• Package / Case: 6-SMD, Gull Wing (all substitutes match)
• Input Type: DC (all substitutes match)
• Voltage - Output (Max): 100V (all substitutes match)
• Voltage - Forward (Vf) (Typ): 1.2V–1.3V (all substitutes within range)
• Current - DC Forward (If) (Max): 50–60 mA (all substitutes within range)
• Vce Saturation (Max): 1V–1.2V (all substitutes within range)

Secondary Considerations:

• Voltage - Isolation: The H11G13SD operates at 5300Vrms. Substitute parts H11G1SR2VM and H11G1SM operate at 4170Vrms, representing a lower isolation specification. H11G1SMT&R operates at 7.5Vpk, which is not directly comparable to Vrms ratings and represents a different isolation class.
• Current Transfer Ratio: H11G13SD specifies 1000% @ 10mA. H11G1SR2VM and H11G1SM match this specification. H11G1SMT&R does not provide current transfer ratio data.
• Operating Temperature: H11G13SD operates -55°C ~ 100°C. H11G1SR2VM and H11G1SM operate -40°C ~ 100°C (narrower low-temperature range). H11G1SMT&R operates -25°C ~ 100°C (further restricted).
• Turn On / Turn Off Time: H11G13SD specifies 5µs, 100µs. H11G1SR2VM and H11G1SM match this specification. H11G1SMT&R provides Rise / Fall Time of 100µs, 20µs (different timing parameters).

Parameter Comparison

Engineering Selection Recommendations

H11G1SR2VM and H11G1SM (onsemi)

Both H11G1SR2VM and H11G1SM are active onsemi products that provide the closest functional alignment to the H11G13SD. These parts maintain identical current transfer ratio specifications (1000% @ 10mA), matching turn-on/turn-off timing (5µs, 100µs), and equivalent electrical characteristics for forward voltage, saturation voltage, and output current. Both are ROHS3 compliant and REACH unaffected.

The primary trade-off is isolation voltage: H11G1SR2VM and H11G1SM operate at 4170Vrms compared to the H11G13SD's 5300Vrms. This represents a 21% reduction in isolation specification. Applications requiring the full 5300Vrms isolation margin should evaluate whether the lower isolation voltage is acceptable for the intended circuit design.

Operating temperature range is narrower for both substitutes (-40°C ~ 100°C versus -55°C ~ 100°C), eliminating low-temperature operation below -40°C. Packaging differs: H11G1SR2VM is supplied in Tape & Reel format, while H11G1SM is supplied in Tube format.

H11G1SMT&R (Isocom Components 2004 LTD)

H11G1SMT&R is an active product from a different manufacturer (Isocom Components 2004 LTD) supplied in Tape & Reel packaging. This part shares the same 6-SMD gull wing package and Darlington output configuration. However, significant parameter differences exist: isolation voltage is specified as 7.5Vpk (not directly comparable to Vrms ratings), current transfer ratio is not provided, and operating temperature range is further restricted to -25°C ~ 100°C. Rise/fall timing is specified as 100µs, 20µs rather than turn-on/turn-off timing. This part represents a lower-specification alternative suitable only for applications with relaxed isolation and temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can H11G1SR2VM or H11G1SM directly replace H11G13SD in existing designs?

A: H11G1SR2VM and H11G1SM are functionally compatible for most applications due to matching output type, package, current transfer ratio, and timing specifications. However, the reduced isolation voltage (4170Vrms versus 5300Vrms) must be evaluated against circuit isolation requirements. If the design margin depends on 5300Vrms isolation, substitution is not appropriate. Both parts are pin-compatible in the 6-SMD gull wing package.

Q: What is the significance of the isolation voltage difference?

A: Isolation voltage specifies the maximum voltage that can be safely applied across the optoisolator's isolation barrier without breakdown. The H11G13SD's 5300Vrms rating provides higher isolation margin than H11G1SR2VM and H11G1SM at 4170Vrms. Applications operating near maximum isolation voltage limits should retain the H11G13SD specification or confirm that 4170Vrms meets safety and regulatory requirements.

Q: Why does H11G1SMT&R show different timing parameters?

A: H11G1SMT&R specifies Rise/Fall Time (100µs, 20µs) rather than Turn On/Turn Off Time (5µs, 100µs). These represent different measurement methodologies and are not directly comparable. H11G1SMT&R's rise time of 20µs is faster than the H11G13SD's turn-off time of 100µs, but the turn-on specification cannot be directly evaluated. This part is not recommended as a direct substitute due to incomplete timing data.

Q: What packaging options are available for substitutes?

A: H11G1SR2VM is supplied in Tape & Reel (TR) format, suitable for automated assembly. H11G1SM is supplied in Tube format, suitable for manual handling and lower-volume applications. Both maintain the same 6-SMD gull wing package footprint as the H11G13SD.

Q: Are all substitute parts RoHS and REACH compliant?

A: H11G1SR2VM and H11G1SM are ROHS3 compliant and REACH unaffected. H11G1SMT&R is also ROHS3 compliant and REACH unaffected. The H11G13SD's compliance status is not specified in available data.

Q: What is the operating temperature impact of substitution?

A: The H11G13SD operates from -55°C to 100°C. H11G1SR2VM and H11G1SM operate from -40°C to 100°C, eliminating operation below -40°C. H11G1SMT&R operates from -25°C to 100°C, further restricting low-temperature operation. Applications requiring full -55°C operation cannot use these substitutes.
