Product details
Overview
S1BBH from Taiwan Semiconductor is a 1 A, 100 V surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring glass-passivated junction, AEC-Q101 qualification, 30 A surge current rating, and 1.1 V max forward voltage at 1 A and 25°C - used in automotive lighting and DC-DC converter freewheeling paths.
For engineers reviewing the S1BBH datasheet, S1BBH pinout, S1BBH application, or S1BBH equivalent, key selection criteria include repetitive peak reverse voltage (100 V), surge capability (30 A @ 8.3 ms), thermal resistance (30 °C/W), RoHS/halogen-free compliance, and J-STD-020 Level 1 moisture sensitivity.
Technical Context
The S1BBH is a single-die, unidirectional silicon PN junction rectifier optimized for high-reliability surface-mount operation. Its glass-passivated chip junction ensures stable reverse leakage (<5 µA at 25°C, <50 µA at 125°C) and robustness against humidity and thermal cycling.
Designed for automated placement and reflow soldering, it meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements. Polarity is marked by a cathode band; terminals are matte tin-plated per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum non-repetitive reverse voltage the device blocks reliably in circuit |
| IF | 1 A continuous - average forward current rating under specified thermal conditions |
| IFSM | 30 A - peak non-repetitive surge current capability for 8.3 ms half-sine wave |
| VF (max) | 1.1 V @ 1 A, 25°C - limits conduction loss and self-heating in power path |
| RθJL | 30 °C/W - junction-to-lead thermal resistance enables direct PCB copper heat sinking |
| IR (max) | 5 µA @ 25°C - low leakage preserves efficiency in high-impedance snubber or hold-up circuits |
| CJ | 12 pF @ 1 MHz, 4 V - influences high-frequency switching noise and EMI in flyback/freewheeling nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semi MUR110E | 100 V VRRM, 1 A IF, but faster recovery (trr = 75 ns vs. S1BBH's ~500 ns); higher VF (1.3 V typ) | Better suited for high-frequency SMPS where reverse recovery loss dominates | Select MUR110E when trr < 100 ns is required; S1BBH preferred for cost-sensitive, lower-frequency automotive lighting |
| Vishay VS-1EQH01-M3 | 100 V VRRM, 1 A IF, AEC-Q101 qualified, same SMB package; VF = 1.05 V (typ), IR = 2 µA @ 25°C | Near-identical automotive use cases; tighter IR spec improves snubber stability | VS-1EQH01-M3 offers marginally better leakage and forward drop; S1BBH provides equivalent performance at lower unit cost |
Compared with MUR110E and VS-1EQH01-M3, the S1BBH delivers balanced trade-offs: AEC-Q101 compliance and robust surge rating at competitive cost, while its moderate recovery time and proven thermal behavior suit 50–500 kHz automotive and industrial rectification without demanding ultra-fast switching.

FAQ
What is the maximum junction temperature rating for the S1BBH?
The S1BBH has a maximum junction temperature (TJ) rating of +150°C, with an operating range from –55°C to +150°C. This allows reliable operation in under-hood automotive environments and thermally constrained industrial PCB layouts. Derating curves in the datasheet specify allowable average forward current versus lead temperature, ensuring safe thermal design when using the device in S1BBH-based power stages.
Is the S1BBH suitable for automotive applications?
Yes, the S1BBH is AEC-Q101 qualified and explicitly listed for automotive applications including car lighting and DC-DC converters. It meets JESD201 Class 2 whisker resistance, J-STD-020 Level 1 moisture sensitivity, and UL 94V-0 flammability - all required for automotive-grade discrete components. The S1BBH's glass-passivated junction and extended temperature range further support its use in automotive systems.
What does the marking code "S1BB" on the S1BBH indicate?
The marking code "S1BB" on the S1BBH identifies it as the 100 V variant within the S1ABH–S1MBH rectifier series. Per the ordering table, "S1xBH" uses "x" to denote voltage grade: "A" = 50 V, "B" = 100 V, "D" = 200 V, etc. Thus, "S1BB" confirms the S1BBH is rated for 100 V repetitive peak reverse voltage (VRRM), matching its electrical specification and packaging data.
How is thermal performance characterized for the S1BBH?
The S1BBH specifies a junction-to-lead thermal resistance (RθJL) of 30 °C/W, measured under standard test conditions. This value enables direct thermal modeling from die to PCB copper land, supporting passive cooling in space-constrained designs. Unlike junction-to-ambient ratings, RθJL reflects performance when leads are soldered to adequately sized copper pads - a key parameter for predicting S1BBH junction temperature in real-world automotive and industrial layouts.
Does the S1BBH have halogen-free and RoHS-compliant construction?
Yes, the S1BBH is both RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. Its molding compound contains no brominated flame retardants or chlorine-based additives, and the matte tin-plated leads meet J-STD-002 solderability requirements. These attributes are confirmed in the official Taiwan Semiconductor S1ABH–S1MBH datasheet Version A2102 and support environmentally regulated production programs using the S1BBH.
