Product details
Overview
S5GBH from Taiwan Semiconductor is a surface-mount silicon rectifier diode rated for 5 A average forward current and 400 V repetitive peak reverse voltage, featuring glass-passivated junction, low forward voltage drop (≤1.1 V at 5 A), and AEC-Q101 qualification for automotive reliability. It serves as a freewheeling or snubber diode in DC-DC converters and car lighting systems.
For engineers reviewing the S5GBH datasheet, S5GBH pinout, S5GBH application, or S5GBH equivalent, key selection factors include its DO-214AA (SMB) package, 200 A non-repetitive surge rating, 150 °C max junction temperature, J-STD-020 Level 1 moisture sensitivity, and RoHS/halogen-free compliance.
Technical Context
The S5GBH is a single-die, unidirectional silicon rectifier with glass-passivated PN junction, optimized for high-reliability surface-mount operation in automotive and industrial power conversion. Its thermal resistance of 13 °C/W (junction-to-lead) supports sustained 5 A conduction under constrained PCB thermal conditions.
Electrical behavior is defined by low VF (≤1.1 V @ 5 A, 25 °C), tight IR control (≤10 μA @ 400 V, 25 °C), and junction capacitance of 40 pF @ 4 V - enabling efficient switching in snubber and freewheeling roles without excessive capacitive loading.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH5L04 | Same DO-214AA package, 5 A / 400 V rating, but VF = 1.15 V (max) and TJ max = 175 °C | Higher TJ rating suits hotter environments; slightly higher VF increases conduction loss by ~5% at full load | Select STTH5L04 only if >150 °C ambient operation is required and layout allows minor efficiency trade-off |
| ON Semi MUR540 | DO-214AA, 5 A / 400 V, ultrafast recovery (trr = 50 ns), VF = 1.25 V (max), AEC-Q101 not claimed | Ultrafast trr reduces switching losses in high-frequency (>100 kHz) converters; lacks automotive qualification | Choose MUR540 for non-automotive SMPS where speed matters more than qualification; avoid in safety-critical vehicle systems |
Compared with STTH5L04 and MUR540, the S5GBH delivers optimal balance of automotive qualification, low VF, and proven thermal performance in 12 V/24 V power rails - making it preferred for cost-sensitive, volume automotive modules requiring zero-bake assembly and long-term field reliability.

FAQ
What is the maximum junction temperature rating for the S5GBH?
The S5GBH has a maximum junction temperature (TJ max) of +150 °C, verified per AEC-Q101 stress testing. This rating allows reliable operation in under-hood automotive environments where ambient temperatures exceed 105 °C. The S5GBH maintains specified electrical parameters up to this limit, provided thermal design accounts for its RθJL of 13 °C/W and RθJA of 47 °C/W.
Is the S5GBH pin-compatible with other parts in the S5xBH series?
No - the S5GBH shares the DO-214AA (SMB) package and two-terminal configuration with S5JBH, S5KBH, and S5MBH, but each variant has distinct VRRM ratings (400 V to 1000 V) and marking codes (S5GB, S5JB, etc.). While mechanical mounting is identical, electrical substitution requires validation of reverse voltage margin and thermal performance for the target application. The S5GBH itself is not interchangeable with higher-voltage variants without circuit review.
Does the S5GBH require moisture sensitivity baking before reflow soldering?
No - the S5GBH is rated J-STD-020 Level 1, meaning it has unlimited floor life at ≤30 °C / 60% RH and requires no pre-reflow baking. This simplifies SMT line integration and eliminates moisture-related popcorning risk. The Level 1 classification is confirmed in the official Taiwan Semiconductor datasheet revision A2102 and applies specifically to the S5GBH in DO-214AA packaging.
What is the forward voltage drop specification for the S5GBH at rated current?
The S5GBH has a maximum forward voltage (VF) of 1.1 V at IF = 5 A and TJ = 25 °C, measured under pulsed conditions (PW = 0.3 ms). At elevated junction temperatures (e.g., 125 °C), VF decreases slightly due to semiconductor physics, but the 1.1 V max remains the design-limiting value for thermal and efficiency calculations at room-temperature startup conditions.
Can the S5GBH be used in freewheeling applications for 24 V commercial vehicle systems?
Yes - the S5GBH is explicitly listed for freewheeling applications in the manufacturer's documentation and supports 24 V systems with ample voltage margin (400 V VRRM). Its 200 A IFSM (8.3 ms) and 150 °C TJ max enable robust operation during motor stall or solenoid de-energization events. AEC-Q101 qualification further validates suitability for commercial vehicle ECU and body control modules.
