Product details

Overview

2A01GHR0G from Taiwan Semiconductor is a 2 A, 50 V glass-passivated standard rectifier diode in DO-204AC (DO-15) package, featuring low forward voltage (1.1 V @ 2 A, 25°C), 70 A surge capability, and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in DC-DC converters and switching-mode power supplies.

For engineers reviewing the 2A01GHR0G datasheet, 2A01GHR0G pinout, 2A01GHR0G application, or 2A01GHR0G equivalent, key selection criteria include repetitive peak reverse voltage (50 V), thermal resistance (R_θJL = 25 °C/W), junction temperature range (–55 to +150 °C), and RoHS/halogen-free compliance for industrial and automotive power conversion designs.

Technical Context

This device is a single-die, silicon planar junction standard rectifier with glass-passivated chip construction, enabling stable operation under high-reliability thermal and surge stress. Its 50 V V_RRM, 2 A average forward current rating, and 70 A non-repetitive surge current (8.3 ms half-sine) support robust performance in unidirectional power conversion paths.

The DO-204AC (DO-15) axial-leaded package provides mechanical stability and solderable pure-tin terminals compliant with J-STD-002. Polarity is marked by a cathode band, and the molding compound meets UL 94V-0 flammability standards.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	50 V - Maximum repetitive reverse voltage before breakdown; defines safe blocking capability in 50 V-rated DC-DC outputs.
I_F	2 A - Continuous average forward current at T_A = 75°C; sets steady-state power handling limit.
I_FSM	70 A - Peak non-repetitive surge current (8.3 ms); supports transient overload tolerance during startup or fault events.
V_F	1.1 V @ 2 A, 25°C - Forward voltage drop; directly determines conduction loss (2.2 W at full load) and thermal design margin.
R_θJL	25 °C/W - Junction-to-lead thermal resistance; enables accurate lead-temperature-based derating without heatsink.
T_J max	+150 °C - Maximum junction temperature; allows operation in under-hood automotive environments with appropriate PCB copper area.

Pinout & Package

Package: DO-204AC (DO-15), axial-leaded, glass-passivated silicon rectifier with cathode band marking. Leads are pure tin-plated and solderable per J-STD-002; weight ≈ 0.400 g.

Pin/Terminal	Circuit Role	Design Meaning
Anode (unmarked end)	Forward current entry point	Connected to lower-potential side of circuit; must be routed with adequate trace width for 2 A continuous current.
Cathode (banded end)	Forward current exit / reverse voltage blocking terminal	Marked by visible band; connects to higher-potential node; reverse leakage <5 µA at 25°C ensures minimal standby loss.

Key Features

Feature	Design Value
Glass-passivated chip junction	Enhances moisture and contamination resistance, improving long-term reliability in humid or chemically aggressive environments.
AEC-Q101 qualified	Validated for automotive applications including engine control modules and body electronics requiring extended temperature cycling and vibration endurance.
Low V_F (1.1 V)	Reduces conduction losses by ~15% vs. legacy 1.3 V rectifiers at 2 A, lowering thermal stress on adjacent components and PCB.
RoHS & halogen-free	Complies with IEC 61249-2-21; eliminates brominated flame retardants and supports environmentally regulated manufacturing and end-of-life processing.

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 MUR220	2 A, 200 V V_RRM; faster recovery (t_rr = 35 ns) but higher V_F (1.3 V); TO-220AC package.	Higher voltage margin suits 200 V systems; TO-220 requires heatsink for same 2 A load.	Select when higher reverse voltage headroom or faster switching is needed; not drop-in due to package and thermal interface differences.
Vishay VS-2A50	2 A, 50 V V_RRM; identical voltage rating; DO-15 package; V_F = 1.15 V @ 2 A; no AEC-Q101 qualification.	Matches 2A01GHR0G voltage and footprint but lacks automotive qualification and has slightly higher conduction loss.	Use in cost-sensitive industrial or consumer applications where AEC-Q101 is not required; verify thermal margin with R_θJA = 65 °C/W.

Compared with MUR220 and VS-2A50, the 2A01GHR0G offers optimal balance of automotive qualification, low V_F, and DO-15 thermal performance-making it preferred for space-constrained, thermally demanding 50 V automotive and industrial rectification where reliability and efficiency are co-prioritized.

FAQ

What is the maximum junction temperature rating for the 2A01GHR0G?

The 2A01GHR0G has a maximum junction temperature (T_J) of +150 °C, validated across its full operating range from –55 °C to +150 °C. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial settings. Derating curves in the datasheet define allowable forward current versus ambient temperature, and the device's R_θJL = 25 °C/W supports precise thermal modeling using lead temperature measurements. The 2A01GHR0G maintains specified electrical parameters within this full junction temperature range.

Is the 2A01GHR0G pin-compatible with other DO-204AC rectifiers like 1N4001 or 1N5401?

Yes, the 2A01GHR0G uses the standard DO-204AC (DO-15) axial package with anode/cathode polarity marked identically to 1N4001 and 1N5401, making it physically interchangeable on PCBs designed for that outline. However, it is not functionally equivalent: 1N4001 is rated for 50 V but only 1 A, while 1N5401 is 3 A but 100 V. The 2A01GHR0G delivers 2 A at 50 V with lower V_F (1.1 V) and AEC-Q101 qualification-key distinctions that require validation in the target circuit's thermal and surge profile.

Does the 2A01GHR0G meet automotive qualification standards?

Yes, the "H" suffix in 2A01GHR0G explicitly denotes AEC-Q101 qualification per version I2105 of the datasheet. This includes stress testing for temperature cycling, humidity bias, mechanical shock, and board-level reliability-validating suitability for automotive powertrain, chassis, and body electronics. The device's glass-passivated junction, halogen-free molding compound, and JESD201 Class 2 whisker resistance further support automotive-grade longevity. Always confirm qualification status via the official TSC certificate for the specific date code batch of 2A01GHR0G.

What is the forward voltage specification for the 2A01GHR0G at elevated temperature?

The 2A01GHR0G forward voltage (V_F) is specified as 1.1 V maximum at I_F = 2 A and T_J = 25 °C. While the datasheet does not list a guaranteed V_F at higher temperatures, typical characteristics show V_F decreases by ~2 mV/°C above 25 °C due to semiconductor physics. At T_J = 125 °C, V_F typically falls to ~0.95 V. This reduction lowers conduction loss but must be balanced against increased leakage current (I_R ≤ 100 µA at 125 °C), which affects standby efficiency in the final 2A01GHR0G design.

How is polarity indicated on the 2A01GHR0G package?

Polarity on the 2A01GHR0G is indicated by a distinct cathode band printed near one end of the DO-204AC (DO-15) cylindrical body. The banded end is the cathode; the opposite, unmarked end is the anode. This marking aligns with industry-standard DO-15 conventions and matches the polarity diagram in the TSC datasheet (Version I2105, Page 4). Correct orientation is critical: reverse installation will block forward current and may cause catastrophic failure under reverse bias if voltage exceeds V_RWM.
