Product details

Overview

S1GBHR5G from Taiwan Semiconductor is a 1 A, 400 V repetitive peak reverse voltage (V_RRM) surface-mount standard silicon rectifier diode in DO-214AA (SMB) package, featuring 1.1 V max forward voltage at 1 A and 30 A surge capability, used in AC/DC front-end rectification for offline SMPS and LED drivers.

For engineers reviewing the S1GBHR5G datasheet, S1GBHR5G pinout, S1GBHR5G application, or S1GBHR5G equivalent, key selection criteria include V_RRM = 400 V, I_F = 1 A, I_FSM = 30 A, T_J_MAX = 150 °C, and DO-214AA mechanical compatibility with automated placement and J-STD-002 solderability.

Technical Context

This single-die standard rectifier operates as a unidirectional current-conducting device with glass-passivated junction for enhanced reliability and moisture resistance (J-STD-020 Level 1). It delivers low conduction loss (V_F ≤ 1.1 V @ 1 A, 25 °C) and high transient robustness (I_FSM = 30 A, 8.3 ms half-sine).

Thermal performance is defined by R_θJL = 30 °C/W, enabling operation up to 150 °C junction temperature. Reverse leakage remains ≤ 5 µA at 25 °C and ≤ 50 µA at 125 °C under rated V_R, supporting stable performance in thermally demanding converter stages.

Key Specifications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1R04	V_RRM = 400 V, I_F = 1 A, but V_F = 1.3 V (typ) - higher conduction loss than S1GBHR5G's 1.1 V max.	Same DO-214AA footprint; suitable where slightly lower efficiency is acceptable for legacy design continuity.	Select when STMicroelectronics sourcing preference applies and 0.2 V higher V_F is tolerable in thermal budget.
ON Semi MUR140	V_RRM = 400 V, I_F = 1 A, but optimized as ultrafast recovery (t_rr ≈ 50 ns); S1GBHR5G is standard recovery (~2 µs).	Better EMI profile in high-frequency converters; not required in <100 kHz SMPS where S1GBHR5G's standard recovery suffices.	Choose MUR140 only if fast recovery is needed; otherwise S1GBHR5G offers lower cost and adequate performance.

Compared with STTH1R04 and MUR140, S1GBHR5G provides the lowest forward voltage among 400 V/1 A standard rectifiers and avoids unnecessary ultrafast complexity-ideal for cost-sensitive, thermally constrained, and low-to-mid frequency power conversion.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) of the S1GBHR5G?

The S1GBHR5G has a V_RRM of 400 V, meaning it reliably blocks reverse voltages up to this level without breakdown. This rating provides sufficient margin for 230 VAC input applications (peak ≈ 325 V), making the S1GBHR5G suitable for universal-input offline power supplies and adapters.

Is the S1GBHR5G compatible with lead-free reflow soldering processes?

Yes, the S1GBHR5G features matte tin-plated leads qualified per J-STD-002 for solderability and complies with JESD 201 Class 2 whisker resistance. Its DO-214AA (SMB) package supports standard lead-free reflow profiles, including peak temperatures up to 260 °C.

What is the forward voltage drop of the S1GBHR5G at rated current?

The S1GBHR5G exhibits a maximum forward voltage (V_F) of 1.1 V at I_F = 1 A and T_J = 25 °C (pulse test, PW = 0.3 ms). This low V_F contributes to reduced conduction losses and improved thermal performance in compact power designs.

Does the S1GBHR5G have a specified junction-to-lead thermal resistance?

Yes, the S1GBHR5G has a typical junction-to-lead thermal resistance (R_θJL) of 30 °C/W. This value enables accurate thermal modeling when mounted on standard PCB copper areas and informs heatsinking decisions for sustained 1 A operation.

How does the S1GBHR5G compare to ultrafast rectifiers like MUR140 in switching behavior?

The S1GBHR5G is a standard recovery rectifier (t_rr ≈ 2 µs), whereas MUR140 is ultrafast (t_rr ≈ 50 ns). In low-frequency (<100 kHz) SMPS, S1GBHR5G's recovery time introduces negligible switching loss-making it more cost-effective and thermally efficient than over-specified ultrafast alternatives.
