Taiwan Semiconductor Corporation S2VH

Overview

S2VH from Taiwan Semiconductor is a surface-mount silicon rectifier diode with 1400 V repetitive peak reverse voltage (V_RRM), 2 A average forward current (I_F), and 50 A surge capability (I_FSM). It features glass passivated junction, AEC-Q101 qualification, and DO-214AA (SMB) package - designed for high-voltage freewheeling and snubber circuits in automotive power systems.

For engineers reviewing the S2VH datasheet, S2VH pinout, S2VH application, or S2VH equivalent, key selection criteria include its 1400 V V_RRM, 1.15 V max forward voltage at 2 A, 1500 ns reverse recovery time, AEC-Q101 qualification, and DO-214AA mechanical compatibility in space-constrained DC/DC and lighting modules.

Technical Context

The S2VH is a single-die, standard recovery rectifier optimized for high-voltage transient suppression and energy recirculation. Its 1400 V V_RRM rating enables use in 800–1000 V bus systems, while its 1500 ns trr supports moderate-frequency switching up to ~50 kHz in non-synchronous topologies.

Thermally, it delivers R_θJL = 16 °C/W and R_θJA = 53 °C/W in DO-214AA (SMB), supporting 2 A continuous conduction at ≤125 °C ambient when mounted on ≥1 cm² copper. The device operates across –55 °C to +150 °C junction temperature range.

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

Compared with VS-2EY140, the S2VH offers lower forward drop and faster recovery; compared with MUR220, it provides 7× higher voltage rating but trades off speed - making S2VH optimal for 1400 V snubbing and freewheeling where efficiency and ruggedness dominate.

Availability

S2VH is available at Aetrix Electronics and suitable for automotive lighting, DC/DC converter design, and industrial snubber circuits requiring stable component supply across extended temperature and voltage ranges.

Supply support for S2VH includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, specializing in power devices, rectifiers, and protection components.

The S2VH belongs to TSC's S2xH series of AEC-Q101-qualified surface-mount rectifiers, engineered specifically for high-reliability automotive and industrial power conversion where voltage margin, surge robustness, and thermal stability are critical.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) of the S2VH?

The S2VH has a V_RRM of 1400 V, confirmed in the Absolute Maximum Ratings table across all versions (A2102). This rating defines the highest reverse voltage the device can block repeatedly without breakdown, making it suitable for high-voltage bus protection and snubber applications where transient margins exceed 1000 V. The S2VH maintains this rating across its full operating temperature range.

Is the S2VH AEC-Q101 qualified, and what does that mean for automotive use?

Yes, the S2VH is explicitly AEC-Q101 qualified per the manufacturer's documentation. This means it has passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), verifying reliability for under-hood automotive environments. For automotive designers, the S2VH meets baseline qualification for use in lighting, EPS, and body control modules without additional component-level qualification effort.

What is the forward voltage drop (V_F) specification for the S2VH at rated current?

The S2VH has a maximum forward voltage of 1.15 V at 2 A and 25°C junction temperature, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents worst-case conduction loss. At elevated temperatures (e.g., 125°C), V_F decreases slightly, but system-level thermal design must still account for up to 2.3 W of dissipation at full 2 A DC load.

Does the S2VH have a specified reverse recovery time (t_rr), and how does it affect circuit performance?

Yes, the S2VH has a typical reverse recovery time of 1500 ns, measured at I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This t_rr value indicates standard recovery behavior - suitable for line-frequency and low-to-moderate frequency (<50 kHz) switching applications like flyback snubbers and freewheeling paths, but not recommended for high-frequency synchronous rectification where ultrafast diodes are required.

What package type and mounting compatibility does the S2VH offer?

The S2VH uses the DO-214AA (SMB) package, with matte tin-plated leads compliant with J-STD-002 solderability standards and moisture sensitivity level 1 per J-STD-020. Its standardized footprint supports automated pick-and-place assembly and reflow soldering without pre-baking. Polarity is marked by a visible cathode band, and the package meets UL 94V-0 flammability requirements for safety-critical layouts.
