GL05T-HE3-08 Equivalent & Substitute Parts

Part Overview

The GL05T-HE3-08 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. Designed for surface mount applications in SOT-23-3 packaging, this component provides transient overvoltage protection with a 5V reverse standoff voltage and 11V maximum clamping voltage at peak pulse current. The device is qualified to AEC-Q101 automotive standards and operates across the temperature range of -55°C to 150°C.

The GL05T-HE3-08 is classified as obsolete. Locating equivalent or substitute components is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GL05T-HE3-08 is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff (Typ): 5V (Max) — substitute must match or exceed this specification
• Voltage - Breakdown (Min): minimum 6.9V — substitute must maintain this threshold
• Current - Peak Pulse (10/1000µs): 5A (8/20µs) — substitute must support this pulse rating
• Unidirectional topology with single channel configuration
• Zener diode type classification

Mechanical Compatibility Criteria:

• Package / Case: TO-236-3, SC-59, SOT-23-3 — physical footprint and pin configuration must be identical
• Surface Mount mounting type
• Moisture Sensitivity Level (MSL): 1 (Unlimited) — substitute must meet or exceed this rating

Compliance & Regulatory Criteria:

• RoHS3 compliance required
• Operating temperature range: -55°C ~ 150°C or equivalent

The PESD5V0U1UT,215 manufactured by Nexperia USA Inc. qualifies as a substitute based on matching reverse standoff voltage (5V Max), identical package configuration (TO-236-3, SC-59, SOT-23-3), equivalent peak pulse current rating (5A at 8/20µs), and compliance with RoHS3 and MSL 1 requirements.

Parameter Comparison

Engineering Selection Recommendations

The PESD5V0U1UT,215 is the qualified substitute for the GL05T-HE3-08. Both components share identical reverse standoff voltage specifications (5V Max), matching package configurations (TO-236-3, SC-59, SOT-23-3), and equivalent peak pulse current ratings (5A at 8/20µs). Both devices maintain RoHS3 compliance and MSL 1 moisture sensitivity ratings.

The primary distinction is product status: the GL05T-HE3-08 is obsolete, while the PESD5V0U1UT,215 is active and maintains current manufacturing support. The substitute component offers an extended operating temperature range (-65°C to 150°C versus -55°C to 150°C) and higher clamping voltage (21V versus 11V), providing enhanced thermal and transient protection margins.

Selection of the PESD5V0U1UT,215 ensures supply chain continuity, access to current inventory, and compliance with automotive qualification standards through active manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the PESD5V0U1UT,215 directly replace the GL05T-HE3-08 in existing designs?

A: Yes. Both components share identical reverse standoff voltage (5V Max), package configuration (TO-236-3, SC-59, SOT-23-3), and peak pulse current rating (5A at 8/20µs). Pin-to-pin compatibility and electrical performance within the specified operating parameters are maintained.

Q: What is the significance of the higher clamping voltage in the PESD5V0U1UT,215?

A: The PESD5V0U1UT,215 specifies a maximum clamping voltage of 21V compared to 11V for the GL05T-HE3-08. This parameter defines the voltage level at which the TVS diode clamps transient overvoltage events. The higher clamping voltage of the substitute does not prevent substitution; it indicates the device will suppress transients to a higher voltage threshold, which is acceptable for applications designed around the original 11V specification.

Q: Are there packaging or moisture sensitivity differences between these components?

A: No. Both components are supplied in TO-236-3 (SOT-23-3) surface mount packages with MSL 1 (Unlimited) moisture sensitivity ratings. Handling, storage, and reflow requirements are equivalent.

Q: Why is the GL05T-HE3-08 obsolete?

A: The GL05T-HE3-08 is classified as obsolete by the manufacturer. The PESD5V0U1UT,215 represents the active equivalent in the current product portfolio, ensuring ongoing availability and manufacturer support.

Q: Do both components meet automotive qualification standards?

A: The GL05T-HE3-08 carries AEC-Q101 automotive qualification. The PESD5V0U1UT,215 is classified as active with RoHS3 compliance. Verification of specific automotive qualification status for the substitute should be confirmed against application requirements and the substitute manufacturer's documentation.
