Product details

Overview

SS13H from Taiwan Semiconductor is a 1A, 30V Schottky barrier surface-mount rectifier in DO-214AC (SMA) package, qualified to AEC-Q101, with 0.50V forward voltage at 1A/25°C, 40A peak surge current, and 125°C maximum junction temperature. It serves as a freewheeling or reverse-battery protection diode in automotive lighting and DC/DC converters.

For engineers reviewing the SS13H datasheet, SS13H pinout, SS13H application, or SS13H equivalent, key selection criteria include its 30V V_RRM, low VF at high temperature, AEC-Q101 qualification, moisture sensitivity level 1, and DO-214AC mechanical compatibility with automated SMT placement.

Technical Context

The SS13H uses a single-die Schottky structure optimized for low forward voltage and fast switching, with guard ring integration for overvoltage robustness. Its 28°C/W junction-to-lead thermal resistance supports reliable 1A continuous operation under constrained board-level cooling.

Rated for -55°C to +125°C junction operation, it delivers 200μA max reverse leakage at 25°C and 6mA at 100°C under rated 30V reverse bias - enabling stable performance in thermally demanding automotive ambient environments.

V_F @ 1A, 25°C	0.50 V - Low conduction loss enables >92% efficiency in 5–12V buck converter freewheel paths.
I_FSM	40 A - Peak non-repetitive surge current; withstands load dump transients in vehicle power networks.
R_θJL	28 °C/W - Junction-to-lead thermal resistance; allows direct heat transfer to PCB copper via cathode pad.
T_J max	125 °C - Maximum junction temperature; aligns with AEC-Q101 Grade 2 requirements for under-hood use.
MSL	Level 1 - No floor life limitation; compatible with standard reflow without dry-pack handling.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-1EQH03-M3/45	Same 30V V_RRM, 1A I_F, but VF = 0.52V @ 1A/25°C; DO-214AC package; AEC-Q101 qualified.	Identical automotive use cases; slightly higher VF increases conduction loss by ~4% at full load.	Preferred where Vishay supply chain alignment or dual-sourcing is required.
ON Semiconductor SB130	30V V_RRM, 1A I_F, VF = 0.55V @ 1A/25°C; DO-214AA (SMB) package; not AEC-Q101 qualified.	Limited to industrial/non-automotive applications due to qualification gap; larger SMB footprint requires layout change.	Cost-sensitive industrial designs where automotive qualification is unnecessary.

Compared with VS-1EQH03-M3/45 and SB130, the SS13H offers the lowest VF in its voltage class among AEC-Q101-qualified DO-214AC Schottkys, delivering superior thermal performance in space-constrained automotive modules without requiring PCB redesign.

FAQ

What is the maximum junction temperature rating for SS13H?

The SS13H has a maximum junction temperature (T_J) rating of +125°C, verified per AEC-Q101 stress testing. This rating applies under continuous 1A forward conduction with proper PCB thermal design. Operation beyond 125°C risks parametric shift and long-term reliability degradation. The SS13H datasheet specifies derating curves confirming usable current down to zero at 125°C ambient when R_θJA = 88°C/W is maintained.

Is SS13H pin-compatible with other parts in the SS1xH family?

Yes, all SS1xH devices - including SS12H, SS13H, SS14H through SS115H - share identical DO-214AC (SMA) package dimensions, pinout, and solder pad layout. Voltage rating differences (20V to 150V) do not affect mechanical fit or assembly; only electrical validation is required when substituting within the same board design.

Does SS13H require special handling for moisture sensitivity?

No. The SS13H is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and may be processed using standard SMT reflow profiles without baking or dry-pack storage. This eliminates moisture-related popcorning risk and simplifies manufacturing logistics for high-volume automotive production.

What is the reverse leakage current specification for SS13H at 100°C?

At T_J = 100°C and rated V_R = 30V, the SS13H exhibits a maximum reverse leakage current (I_R) of 6 mA. This value is confirmed in the Electrical Specifications table on page 2 of the official TSC SS12H–SS115H datasheet (Version B2305). It remains stable across the full 100°C operating range, supporting reliable blocking in hot under-hood environments.

Can SS13H be used as a direct replacement for SB130 in existing designs?

SS13H is not a direct replacement for SB130 due to package mismatch: SB130 uses DO-214AA (SMB), while SS13H uses DO-214AC (SMA). Though both are 30V/1A Schottkys, the SMA body is smaller (4.06 × 2.29 mm vs. SMB's 4.6 × 2.7 mm), requiring PCB land pattern revision. Additionally, SS13H is AEC-Q101 qualified; SB130 is not - critical for automotive deployment.
