Product details

Overview

SS26H from Taiwan Semiconductor is a 2 A, 60 V Schottky barrier surface-mount rectifier in DO-214AA (SMB) package, qualified to AEC-Q101, with 0.70 V forward voltage at 2 A and 25°C, 5 mA reverse current at 60 V and 100°C, and 50 A surge capability - used in automotive DC/DC converters and reverse battery protection circuits.

For engineers reviewing the SS26H datasheet, SS26H pinout, SS26H application, or SS26H equivalent, key selection criteria include its 60 V V_RRM, low VF at high temperature, AEC-Q101 qualification, SMB package thermal performance (R_θJL = 24°C/W), and suitability for high-frequency freewheeling in constrained automotive power stages.

Technical Context

The SS26H operates as a single-die Schottky rectifier optimized for low-loss unidirectional conduction in 12 V–48 V automotive and industrial DC/DC topologies. Its guard ring structure provides over-voltage robustness, while JESD201 Class 2 whisker resistance and moisture sensitivity level 1 support automated SMT assembly without baking.

Thermal design relies on its 24°C/W junction-to-lead resistance and 70°C/W junction-to-ambient rating, enabling 2 A continuous operation up to 125°C ambient when properly mounted on copper pour. Reverse leakage remains below 5 mA at 100°C and rated 60 V, supporting stable operation in thermally demanding engine-bay environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	60 V - maximum repetitive reverse voltage; defines safe blocking capability in 48 V system reverse polarity protection
I_F	2 A - continuous forward current rating; supports typical output stage sizing in sub-100 W DC/DC modules
V_F @ 2 A, 25°C	0.70 V - forward drop determines conduction loss (1.4 W at 2 A); lower than silicon diodes for improved efficiency
I_R @ 60 V, 100°C	5 mA - elevated-temperature leakage sets minimum hold-off margin in hot-start conditions
I_FSM	50 A - non-repetitive surge rating; withstands load dump transients in automotive 12 V systems
T_J max	150°C - maximum junction temperature enables operation in under-hood environments with limited airflow
R_θJL	24°C/W - junction-to-lead thermal resistance allows direct heat transfer to PCB copper, critical for thermal reliability

Pinout & Package

Package: DO-214AA (SMB), surface-mount plastic case with matte tin-plated leads, cathode indicated by band. Weight: 0.093 g.

FAQ

What is the maximum junction temperature rating for SS26H?

The SS26H has a maximum junction temperature (T_J) rating of +150°C, verified per AEC-Q101 stress testing. This allows sustained 2 A operation in high-ambient environments such as engine compartments when mounted on adequate copper area. The device's thermal resistance (R_θJL = 24°C/W) ensures predictable junction heating under load, and derating curves in the datasheet confirm usable current down to –55°C storage temperature.

Is SS26H suitable for reverse battery protection in 12 V automotive systems?

Yes, SS26H is explicitly designed for reverse battery protection in 12 V automotive systems. Its 60 V V_RRM exceeds ISO 7637-2 Pulse 5a load dump requirements (+120 V peak), and its AEC-Q101 qualification validates reliability under automotive thermal and vibration stresses. With only 5 mA reverse leakage at 100°C and 60 V, it maintains low standby loss even in hot under-hood conditions.

Does SS26H have a halogen-free and RoHS-compliant construction?

Yes, SS26H uses halogen-free molding compound and meets RoHS Directive 2011/65/EU requirements. The matte tin-plated leads comply with J-STD-002 for solderability, and the entire construction satisfies JESD201 Class 2 whisker resistance. These attributes are confirmed in the official Taiwan Semiconductor product specification document Version B2306.

What is the forward voltage of SS26H at elevated temperature?

At 2 A forward current and 100°C junction temperature, SS26H exhibits a typical forward voltage (V_F) of 0.65 V - lower than its 0.70 V value at 25°C. This negative temperature coefficient improves thermal stability in high-power-density designs. The datasheet specifies this value under pulse test conditions (PW = 0.3 ms), and the trend holds across the full 25–150°C operating range.

What packaging and reel quantity is offered for SS26H?

SS26H is supplied in DO-214AA (SMB) package on 3,000-piece tape-and-reel format, per the official Taiwan Semiconductor ordering information. The reel complies with EIA-481 standards, and the device marking "SS26" is laser-etched on the cathode-band side. Moisture sensitivity level is rated at Level 1 (per J-STD-020), eliminating bake requirements prior to SMT placement.
