Product details
Overview
SS13 from Taiwan Semiconductor is a 1A, 30V Schottky barrier surface-mount rectifier in DO-214AC (SMA) package, optimized for high-efficiency DC/DC conversion with low forward voltage (0.50 V at 1 A, 25°C), high surge capability (40 A IFSM), and junction temperature up to +150°C. It serves as a primary output rectifier in compact AC/DC adapters and switching power supplies.
For engineers reviewing the SS13 datasheet, SS13 pinout, SS13 application, or SS13 equivalent, key selection criteria include its 30 V VRRM rating, 0.50 V VF at 1 A/25°C, 200 µA IR at 25°C, thermal resistance (RθJL = 28°C/W), and DO-214AC mechanical compatibility with automated SMT assembly.
Technical Context
The SS13 operates as a single-die, unidirectional Schottky rectifier with cathode-band polarity marking and no internal guard ring required for its 30 V rating. Its low VF enables reduced conduction loss in high-frequency switching topologies, while its 40 A IFSM supports transient overload handling in SMPS secondary-side rectification.
Thermally, it features RθJL = 28°C/W and RθJA = 88°C/W, enabling reliable operation up to TJ = +150°C when mounted on standard 1-inch² copper pad. The device meets J-STD-020 moisture sensitivity level 1 and JESD 201 class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse voltage before breakdown; sets safe operating margin for 24 V output rails. |
| IF | 1 A continuous - Rated average forward current under specified thermal conditions; defines steady-state power delivery capacity. |
| VF @ 1 A, 25°C | 0.50 V - Low conduction loss enabling >92% efficiency in 5–12 V DC/DC converters at full load. |
| IR @ 30 V, 25°C | 200 µA - Minimal leakage ensures low standby power in always-on adapter designs. |
| IFSM | 40 A - Peak non-repetitive surge current capability; withstands inrush and fault transients without failure. |
| TJ max | +150°C - Extended junction temperature rating allows operation in thermally constrained enclosures without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MBR130LSFT1G | VRRM = 30 V, VF = 0.45 V @ 1 A/25°C, RθJA = 75°C/W, SOD-123FL package | Smaller footprint but lower thermal mass; limited to <0.7 A continuous in same layout | Select for space-constrained designs where peak current is <0.8 A and board area is premium. |
| SS14 | VRRM = 40 V, VF = 0.50 V @ 1 A/25°C, identical DO-214AC package and thermal specs | Higher reverse margin suitable for 36 V systems; same layout and assembly process | Choose when system-level overvoltage transients exceed 30 V or design margin requires ≥40 V rating. |
Compared with MBR130LSFT1G and SS14, the SS13 offers optimal balance of 30 V rating, 0.50 V VF, and DO-214AC thermal performance-making it ideal for cost-sensitive 24 V adapter outputs where layout reuse and thermal headroom are critical.

FAQ
What is the maximum junction temperature rating for the SS13?
The SS13 has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet revision R2305. This rating applies under continuous 1 A forward current with adequate PCB copper thermal relief. Operation above this limit risks irreversible parametric shift or bond-wire failure. Always verify thermal design using RθJL = 28°C/W and actual board layout.
Does the SS13 have a built-in guard ring for overvoltage protection?
No-the SS13 does not incorporate a guard ring. Guard ring protection is explicitly listed only for SS12–SS14 in the "Features" section of the datasheet, but the SS13's 30 V VRRM rating is achieved via optimized epitaxial layer design rather than guard ring structure. Its dV/dt rating remains 10,000 V/µs, confirming inherent transient robustness without additional guard ring implementation.
What is the forward voltage of the SS13 at 100°C junction temperature?
At IF = 1 A and TJ = 100°C, the SS13 exhibits a typical forward voltage of 0.40 V, as confirmed in the "ELECTRICAL SPECIFICATIONS" table (page 2, R2305). This represents a 20% reduction from its 25°C VF of 0.50 V-consistent with the negative temperature coefficient of Schottky diodes-and directly improves efficiency in thermally stressed operating conditions.
Is the SS13 RoHS compliant and halogen-free?
Yes-the SS13 is RoHS compliant and halogen-free, as stated in the "FEATURES" section of the Taiwan Semiconductor SS12–SS115 datasheet (R2305). Compliance is verified per EU Directive 2011/65/EU and IEC 61249-2-21:2011. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002 solderability standards.
What is the moisture sensitivity level (MSL) of the SS13?
The SS13 has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it is not humidity-sensitive and may be stored indefinitely at ≤30°C/60% RH without baking prior to reflow. This eliminates floor-life constraints and simplifies SMT line logistics-unlike higher-MSL components that require dry-packaging and time-limited assembly windows.
