Product details

Overview

1T5G from Taiwan Semiconductor is a single-die standard rectifier diode rated for 600 V repetitive peak reverse voltage (V_RRM), 1 A average forward current (I_F), and 30 A non-repetitive surge current (I_FSM), housed in the TS-1 package with pure tin-plated leads. It delivers low forward voltage drop (1.0 V max at 1 A, 25°C) and supports DC-DC converters and switching-mode inverters requiring reliable 600 V blocking capability.

For engineers reviewing the 1T5G datasheet, 1T5G pinout, 1T5G application, or 1T5G equivalent, key selection considerations include its 600 V V_RRM, 1.0 V V_F max, TS-1 mechanical outline, AEC-Q101 qualification option (1T5GH), and junction-to-ambient thermal resistance of 100 °C/W - all critical for thermal design and automotive-grade reliability validation.

Technical Context

The 1T5G operates as a unidirectional silicon PN junction rectifier optimized for general-purpose and switching-mode power conversion. Its 600 V V_RRM rating enables use in mid-voltage DC-DC stages and auxiliary rails, while its 1 A continuous current and 30 A 8.3 ms surge capability support transient load handling without derating in compact layouts.

Thermally, the TS-1 package provides 100 °C/W R_θJA, and the device maintains ≤5 µA reverse leakage at 25°C and ≤100 µA at 125°C - enabling stable operation across industrial ambient ranges. The cathode band marking and JESD201 Class 2 whisker compliance ensure manufacturability and long-term solder joint integrity.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - maximum repetitive reverse voltage the diode blocks without breakdown; defines safe operating range in 400–600 V bus applications
I_F	1 A - average forward current rating at TA = 25°C; determines continuous power-handling capacity in linear or PWM rectification
I_FSM	30 A - peak non-repetitive surge current (8.3 ms half-sine); supports inrush and fault-current tolerance in SMPS input stages
V_F max	1.0 V @ 1 A, 25°C - forward voltage drop directly impacts conduction loss and thermal rise in high-duty-cycle operation
T_J max	+150 °C - maximum junction temperature; sets upper thermal limit for derating curves and heatsink sizing
R_θJA	100 °C/W - junction-to-ambient thermal resistance; used to calculate temperature rise under given power dissipation
C_J	10 pF @ 1 MHz, 4 V - junction capacitance affects high-frequency switching losses and EMI in fast-switching topologies

Pinout & Package

Package: TS-1 - surface-mount, 3 mm miniature body with gull-wing leads, UL 94V-0 molding compound, pure tin plating per J-STD-002, and cathode polarity indicated by band.

Pin/Terminal	Circuit Role	Design Meaning

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor MUR160	600 V V_RRM, 1 A I_F, but ultrafast recovery (75 ns) vs. standard recovery (~2 µs); higher V_F (1.3 V)	Better suited for high-frequency SMPS (>100 kHz); less optimal for low-noise, low-loss 50–100 kHz designs	Select MUR160 only when fast recovery is required; otherwise 1T5G offers lower conduction loss and cost
Vishay VS-1EWH06	600 V V_RRM, 1 A I_F, same TS-1 package, but higher V_F (1.15 V) and no AEC-Q101 option	Lacks automotive qualification path; slightly higher thermal resistance (110 °C/W)	Use VS-1EWH06 where AEC-Q101 is not required and minor efficiency penalty is acceptable

Compared with MUR160 and VS-1EWH06, the 1T5G provides the lowest forward voltage (1.0 V) and an AEC-Q101-qualified variant, making it optimal for thermally constrained, cost-sensitive, and automotive-qualified 600 V rectification - without compromising surge robustness or manufacturability.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for the 1T5G?

The 1T5G has a V_RRM of 600 V, as confirmed in the Absolute Maximum Ratings table across all versions of the 1T1G–1T7G series. This value is fixed for the 1T5G marking code and defines its safe blocking capability in circuits with up to 600 V reverse bias. Exceeding this voltage risks avalanche breakdown and permanent damage to the 1T5G.

Is the 1T5G RoHS and halogen-free compliant?

Yes, the 1T5G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the official documentation. Its TS-1 package uses green molding compound and pure tin-plated leads, meeting both environmental and solderability requirements for modern electronics manufacturing.

Does the 1T5G have an AEC-Q101 qualified version?

Yes - the AEC-Q101 qualified version of the 1T5G is designated as 1T5GH. The "H" suffix indicates full AEC-Q101 qualification, including stress testing for temperature cycling, humidity, and mechanical shock. This makes the 1T5GH suitable for automotive body electronics and infotainment power supplies where qualification is mandatory.

What is the forward voltage (V_F) specification for the 1T5G at rated current?

The 1T5G 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 for 1T5G–1T7G. This value is measured under pulse conditions (PW = 0.3 ms) and represents the upper limit for conduction loss calculation in thermal design of the 1T5G.

What package type does the 1T5G use, and what are its key mechanical attributes?

The 1T5G uses the TS-1 surface-mount package: a 3 mm miniature body with gull-wing leads, UL 94V-0 flammability-rated molding compound, pure tin plating compliant with J-STD-002, and JESD201 Class 2 whisker resistance. Polarity is marked by a cathode band, and typical weight is 0.200 g.
