SS115LH Equivalent & Substitute Parts Reference

Part Overview

The Taiwan Semiconductor Corporation SS115LH is classified under the Diodes, Rectifiers category, featuring a Schottky technology with key parameters of 1A average rectified current and 150V maximum DC reverse voltage. Its configuration as a surface mount device (SOD-123) with a maximum forward voltage of 900 mV at 1 A, AEC-Q101 automotive qualification, and RoHS3 compliance defines its intended applications and restrictions. With the product status listed as "Not For New Designs," alternative models may be required to fulfill ongoing production requirements or address long-term availability and compliance concerns.

Key Parameters

Substitute Part Grouping Explanation

Substitute diodes and rectifiers are identified based on an exact match of core electrical, mechanical, and compliance parameters. For the SS115LH, the following parameters are strictly compared: product category, technology type (Schottky), voltage and current ratings, forward voltage at rated current, reverse leakage, recovery speed, qualification (AEC-Q101), mounting type, package/case, operating temperature, RoHS status, and REACH status. Only components meeting the same or defined alternate values for these parameters within the authorized product category are considered valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

The SS115LH is marked as "Not For New Designs" while the substitute SS115LWH is "Active." Both parts are from the same manufacturer, qualify for automotive applications under AEC-Q101, and are ROHS3 and REACH compliant. Use of SS115LWH as a substitute may be prioritized based on product status and inventory availability to ensure continued compliance and supply chain stability in authorized applications.

Frequently Asked Questions (FAQ)

Q1: What parameters are required when selecting a substitute for the SS115LH Schottky rectifier?
A1: Substitute must meet documented values for product category, voltage rating, current rating, forward voltage at specified current, reverse leakage, operating temperature, qualification, mounting type, package/case type, RoHS status, and REACH status.

Q2: Are there packaging or mounting differences between the SS115LH and SS115LWH?
A2: SS115LH uses SOD-123 (Sub SMA) and SS115LWH uses SOD-123W. Surface mount technology is used in both cases, but physical package details should be reviewed where exact fit is required.

Q3: How does compliance affect substitution decisions for automotive applications?
A3: Both SS115LH and SS115LWH have AEC-Q101 automotive qualification and are RoHS3 and REACH compliant.

Q4: Is there a difference in inventory status between the SS115LH and its substitute?
A4: The SS115LH is not for new designs, while the SS115LWH is active with significant inventory reported.

Q5: Does the voltage rating, current rating, or speed differ between SS115LH and SS115LWH?
A5: The voltage rating (150 V), average rectified current (1A), and speed are equivalent in both parts. Voltage forward (Vf) and reverse leakage values are also defined and comparable.
