Product details

Overview

S2JH from Taiwan Semiconductor is a 600 V, 2 A surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring 50 A surge capability, 1.15 V max forward voltage at 2 A, and 1 µA max reverse leakage at 25°C - used for freewheeling and snubber circuits in automotive DC-DC converters.

For engineers reviewing the S2JH datasheet, S2JH pinout, S2JH application, or S2JH equivalent, key selection criteria include repetitive peak reverse voltage (600 V), thermal resistance (R_θJA = 53 °C/W), junction temperature range (–55 to +150 °C), and AEC-Q101 qualification for automotive reliability validation.

Technical Context

The S2JH is a single-die, standard recovery rectifier with glass-passivated junction and cathode-band polarity marking. Its 1500 ns reverse recovery time (trr) and 30 pF junction capacitance at 4 V bias reflect trade-offs between switching speed and low-loss conduction.

Designed for surface-mount automated assembly, it meets J-STD-020 moisture sensitivity level 1 and JESD201 Class 2 whisker resistance. The DO-214AA (SMB) package supports 2 A continuous forward current with derating above 75°C ambient per the published forward current derating curve.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - maximum non-repetitive reverse voltage the device blocks without breakdown
I_F	2 A - continuous average forward current rating at T_A = 75°C (derated from 2 A at 25°C)
I_FSM	50 A - peak non-repetitive surge current for 8.3 ms half-sine wave, critical for inductive load turn-off
V_F (max)	1.15 V @ I_F = 2 A, T_J = 25°C - defines conduction loss and thermal dissipation in high-current paths
R_θJA	53 °C/W - junction-to-ambient thermal resistance under standard PCB mounting, determines heatsinking needs
t_rr	1500 ns - reverse recovery time at I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A - impacts switching losses in hard-commutated circuits
T_J (max)	+150 °C - maximum allowable junction temperature, sets upper limit for power dissipation and ambient design

Pinout & Package

Package: DO-214AA (SMB), molded epoxy case with matte tin-plated leads, UL 94V-0 rated, polarity indicated by cathode band.

Pin/Terminal	Circuit Role	Design Meaning

Cathode	Forward current exit terminal / reverse voltage blocking node	Marked by band; connects to higher-potential node; must withstand full V_RRM when reverse-biased

Key Features

Feature	Design Value

50 A I_FSM	Supports robust operation during inductive kick events in motor drivers and solenoid controls
Moisture sensitivity level 1	Enables direct placement without baking, reducing manufacturing overhead in SMT lines

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R06	600 V, 2 A, 1.7 V V_F (max), 50 ns t_rr, TO-220AC package	Ultrafast recovery vs. standard recovery; higher V_F; through-hole mounting	Preferred where fast switching and higher surge tolerance outweigh V_F penalty and board space constraints

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for S2JH?

The S2JH has a maximum repetitive peak reverse voltage (V_RRM) of 600 V, as specified in the Absolute Maximum Ratings table. This value is fixed for the S2JH variant within the S2AH–S2VH series and defines the highest reverse voltage the diode can block continuously without breakdown under normal operating conditions.

Is S2JH qualified for automotive applications?

Yes, the S2JH is AEC-Q101 qualified per the manufacturer's documentation. This qualification confirms that the S2JH has passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), making it suitable for use in automotive electronic control units, lighting modules, and powertrain-related subsystems.

What is the forward voltage (V_F) specification for S2JH at rated current?

The S2JH has a maximum forward voltage (V_F) of 1.15 V at I_F = 2 A and T_J = 25°C, as stated in the Electrical Specifications table. This value reflects conduction loss under nominal conditions and is measured using a 0.3 ms pulse test to avoid self-heating effects.

What package type does S2JH use, and what are its key mechanical features?

The S2JH uses the DO-214AA (SMB) surface-mount package. Key mechanical features include UL 94V-0 rated molding compound, matte tin-plated leads compliant with J-STD-002 solderability, polarity indicated by cathode band, and moisture sensitivity level 1 per J-STD-020 - enabling direct placement without pre-baking.

Does S2JH have a specified reverse recovery time (t_rr)?

Yes, the S2JH has a typical reverse recovery time (t_rr) of 1500 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This parameter is documented in the Electrical Specifications section and applies directly to the S2JH variant as part of the S2xH family characterization.
