Product details

Overview

3A100H from Taiwan Semiconductor is a 3 A, 1000 V AEC-Q101-qualified standard silicon rectifier diode in DO-204AC (DO-15) package, featuring 1.1 V max forward voltage at 3 A, 120 A surge capability, and 17 °C/W junction-to-lead thermal resistance - used in automotive-grade DC-DC converters and switching inverters.

For engineers reviewing the 3A100H datasheet, 3A100H pinout, 3A100H application, or 3A100H equivalent, key selection criteria include peak reverse voltage rating (1000 V), AEC-Q101 qualification status, thermal resistance (R_θJL = 17 °C/W), and DO-15 mechanical compatibility for high-reliability power conversion designs.

Technical Context

This device is a single-die, glass-passivated, standard recovery rectifier optimized for high-efficiency AC/DC and DC/DC conversion. Its 1000 V V_RRM, 120 A I_FSM, and low 1.1 V V_F support robust operation under repetitive surge and continuous conduction mode.

The DO-204AC (DO-15) package enables surface-mount-compatible through-hole assembly with pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. Polarity is marked by cathode band.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1000 V - maximum non-repetitive reverse blocking voltage before breakdown
I_F	3 A - continuous average forward current at T_L = 75 °C
I_FSM	120 A - peak non-repetitive surge current (8.3 ms half-sine)
V_F	≤1.1 V @ 3 A, 25 °C - low conduction loss enabling high-efficiency power stages
R_θJL	17 °C/W - thermal resistance from junction to lead, critical for heatsinkless PCB layout
Junction Temp	−55 to +150 °C - operational range supporting automotive under-hood environments
AEC-Q101	Qualified - validated for automotive electronic systems per stress test requirements

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH3L06S	600 V V_RRM, 3 A I_F, TO-220AC package, no AEC-Q101	Lower voltage rating; requires redesign for ≥700 V systems; unsuitable for automotive	Select only for cost-sensitive industrial supplies where 600 V margin suffices and qualification is not required
ON Semi MUR3100CT	1000 V V_RRM, dual common-cathode configuration, TO-220AB package, faster recovery (~75 ns)	Dual-diode layout enables center-tapped transformer designs; higher thermal mass but larger footprint	Prefer when dual-output or fast-recovery is needed; avoid if single-diode DO-15 footprint and AEC-Q101 are mandatory

Compared with STTH3L06S and MUR3100CT, the 3A100H uniquely combines 1000 V rating, AEC-Q101 qualification, and DO-15 form factor - making it the only drop-in solution for space-constrained automotive rectification where qualification and voltage margin are non-negotiable.

FAQ

What is the peak repetitive reverse voltage rating of the 3A100H?

The 3A100H has a peak repetitive reverse voltage (V_RRM) rating of 1000 V, verified per JEDEC test conditions. This rating ensures reliable blocking performance in high-voltage DC-DC and inverter applications where transient overvoltages may reach 90% of rated V_RRM. The 3A100H maintains this specification across its full operating junction temperature range (−55 to +150 °C).

Is the 3A100H qualified to AEC-Q101, and what does that mean for design use?

Yes, the 3A100H carries full AEC-Q101 qualification, confirmed by Taiwan Semiconductor's certification documentation. This means the 3A100H has passed stress tests for temperature cycling, humidity bias, ESD, and high-temperature operating life - making it suitable for automotive powertrain and chassis applications. The "H" suffix in 3A100H explicitly denotes this qualification status.

What is the forward voltage drop of the 3A100H at rated current?

The 3A100H exhibits a maximum forward voltage (V_F) of 1.1 V at 3 A forward current and 25 °C junction temperature, measured under pulsed conditions (PW = 0.3 ms). At elevated temperatures (125 °C), V_F decreases slightly due to semiconductor physics, remaining within design-safe margins for thermal modeling in the 3A100H.

Does the 3A100H have a specified junction-to-ambient thermal resistance?

Yes, the 3A100H has a typical junction-to-ambient thermal resistance (R_θJA) of 52 °C/W under standard JEDEC test conditions (single device on 1-inch² FR-4 board, 2 oz copper). However, its lower junction-to-lead resistance (R_θJL = 17 °C/W) makes thermal performance highly dependent on PCB copper area and lead soldering quality - a key design consideration for the 3A100H.

What packaging options are available for the 3A100H?

The 3A100H is supplied in DO-204AC (DO-15) package with two standard packing formats: 3,500 units per tape-and-reel (ordering code 3A100HH) and 1,500 units per ammo box (ordering code 3A100HA0G). Both variants retain the same AEC-Q101 qualification, marking, and electrical specifications as the base 3A100H part.
