Product details

Overview

1T5GH from Taiwan Semiconductor is a 1 A, 600 V repetitive peak reverse voltage (V_RRM) standard silicon rectifier diode in TS-1 package, featuring low forward voltage drop (1.0 V max at 1 A, 25°C), high surge current capability (30 A, 8.3 ms), and AEC-Q101 qualification for automotive-grade reliability.

For engineers reviewing the 1T5GH datasheet, 1T5GH pinout, 1T5GH application, or 1T5GH equivalent, key selection criteria include its 600 V blocking rating, 100 °C/W junction-to-ambient thermal resistance, TS-1 miniature body with pure tin-plated leads, and suitability for DC-DC converters requiring robust surge handling and RoHS/halogen-free compliance.

Technical Context

The 1T5GH operates as a single-die, unidirectional standard rectifier with cathode-band polarity indication. Its electrical behavior is defined by a maximum forward voltage of 1.0 V at 1 A/25°C, reverse leakage of ≤5 µA at 25°C and ≤100 µA at 125°C, and junction capacitance of 10 pF at 1 MHz/4 V.

Thermally, it supports operation from −55°C to +150°C junction temperature, with derating required above 25°C ambient per the forward current derating curve. The TS-1 package enables surface-mount assembly with J-STD-002 solderability and JESD201 Class 2 whisker resistance.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - Maximum repetitive reverse voltage the device blocks without breakdown; defines usable input voltage range in rectification circuits.
I_F	1 A - Continuous average forward current rating; sets steady-state power delivery capacity in linear or switching supplies.
I_FSM	30 A - Non-repetitive surge current tolerance for 8.3 ms half-sine wave; critical for handling inrush or transient overloads.
V_F (max)	1.0 V - Maximum forward voltage at 1 A and 25°C; directly impacts conduction loss and thermal rise in high-efficiency designs.
R_θJA	100 °C/W - Junction-to-ambient thermal resistance; determines required PCB copper area or heatsinking for safe 1 A operation at elevated ambient.
Junction Temp	−55°C to +150°C - Operating temperature envelope; enables use in under-hood automotive and industrial environments.

Pinout & Package

Package: TS-1 - 3 mm miniature molded surface-mount package with gull-wing leads, UL 94V-0 rated compound, pure tin plating, and cathode band polarity marking.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry terminal	Connected to lower-potential side (e.g., transformer secondary center-tap or switch node) in half-wave or full-wave rectifier configurations.
Cathode	Forward current exit terminal	Marked with band; connects to output filter capacitor or load return; defines direction of DC current flow and reverse voltage blocking orientation.

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar standard rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1R06U	Same 1 A / 600 V rating; TO-220AC package; higher V_F (1.15 V typ); no AEC-Q101 qualification.	Requires through-hole mounting and heatsink; unsuitable for automotive under-hood use due to qualification gap.	Select when board-level heatsinking is available and automotive qualification is not required.
ON Semi MUR160	1 A / 600 V ultrafast recovery (t_rr = 50 ns); DO-41 package; V_F = 1.15 V; no AEC-Q101.	Higher switching speed reduces EMI in high-frequency SMPS but lacks automotive reliability validation and surface-mount compatibility.	Prefer for >100 kHz switching topologies where reverse recovery matters more than surge robustness or qualification.

Compared with STTH1R06U and MUR160, the 1T5GH offers AEC-Q101 qualification, TS-1 SMT compatibility, and lower V_F, making it optimal for space-constrained, automotive-grade rectification where surge immunity and thermal reliability outweigh ultrafast recovery needs.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for the 1T5GH?

The 1T5GH has a V_RRM of 600 V, meaning it can reliably block up to 600 V of reverse voltage in repetitive operation without breakdown. This rating is confirmed in the Absolute Maximum Ratings table on page 2 of the official Taiwan Semiconductor datasheet (Version H2104). It defines the upper limit for input voltage or reflected spike handling in rectifier applications.

Is the 1T5GH AEC-Q101 qualified?

Yes, the "H" suffix in 1T5GH explicitly denotes AEC-Q101 qualification per the Ordering Information section (page 3, Version H2104). This certification covers stress testing for temperature cycling, humidity, mechanical shock, and high-temperature operating life-making the 1T5GH suitable for automotive power electronics such as lighting and body control modules.

What is the forward voltage (V_F) specification for the 1T5GH at rated current?

The 1T5GH has a maximum forward voltage of 1.0 V at I_F = 1 A and T_J = 25°C, as specified in the Electrical Specifications table (page 2, Version H2104). This value is lower than earlier variants like 1T1G–1T2G (1.1 V max), contributing to reduced conduction loss and improved thermal performance in continuous-duty rectifier circuits.

What package type does the 1T5GH use, and what are its key mechanical features?

The 1T5GH uses the TS-1 surface-mount package: a 3 mm miniature molded body with gull-wing leads, UL 94V-0 flammability rating, pure tin plating compliant with J-STD-002, and cathode polarity marked by a band. Its weight is approximately 0.200 g, and it passes JESD201 Class 2 whisker testing for long-term solder joint reliability.

How does the 1T5GH compare to the 1T6GH and 1T4GH in terms of voltage rating and application scope?

The 1T5GH (600 V), 1T6GH (800 V), and 1T4GH (400 V) share identical current rating (1 A), thermal specs (R_θJA = 100 °C/W), and package (TS-1), differing only in V_RRM. The 1T5GH targets mid-range applications like 48 V telecom supplies and 24 V industrial SMPS, whereas 1T4GH suits lower-voltage inputs and 1T6GH addresses higher-reflected-voltage flyback or PFC stages.
