Product details
Overview
SS16LWH from Taiwan Semiconductor is a 1A, 60V Schottky barrier surface-mount rectifier in SOD-123W package, featuring 0.70V max forward voltage at 1A and 100µA max reverse leakage at 25°C, with AEC-Q101 qualification for automotive-grade reliability in DC/DC converters and reverse battery protection circuits.
For engineers reviewing the SS16LWH datasheet, SS16LWH pinout, SS16LWH application, or SS16LWH equivalent, key selection criteria include its 60V VRRM rating, 30A IFSM surge capability, junction temperature range up to +150°C, and SOD-123W footprint compatibility with automated placement and J-STD-002 solderability.
Technical Context
The SS16LWH implements a single-die Schottky junction optimized for low forward voltage drop and fast switching, enabling high-efficiency operation in high-frequency DC/DC conversion. Its guard ring structure provides overvoltage protection, and the device operates across -55°C to +150°C junction temperature range.
Thermal performance is defined by 25°C/W junction-to-lead (RθJL) and 80°C/W junction-to-ambient (RθJA) resistance values, supporting stable power dissipation in compact layouts. Moisture sensitivity level is rated at Level 1 per J-STD-020, eliminating bake requirements prior to reflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse voltage before breakdown; defines safe operating limit in reverse-biased applications like freewheeling or reverse polarity protection. |
| IF | 1 A - Continuous forward current rating; supports steady-state conduction in low-voltage power rails without derating below 125°C ambient. |
| VF (max) | 0.70 V @ 1A, 25°C - Low forward voltage minimizes conduction loss and improves system efficiency in high-frequency switching topologies. |
| IR (max) | 100 µA @ 60V, 25°C - Low reverse leakage preserves battery life in always-on automotive modules and reduces standby power loss. |
| IFSM | 30 A - Peak non-repetitive surge current handling; withstands inrush and transient events in automotive load-dump scenarios. |
| TJ max | +150°C - Extended junction temperature rating enables deployment in under-hood automotive environments without thermal derating penalties. |
Pinout & Package
Package: SOD-123W - Surface-mount plastic case with matte tin-plated leads, UL 94V-0 molding compound, cathode indicated by band, weight 0.016g, JEDEC DO-219 AB compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of circuit; enables unidirectional conduction when cathode is at higher potential. |
| Cathode | Forward current exit point | Marked by band; ties to higher-potential node (e.g., input rail or switch node) in freewheeling or clamping configurations. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS16HE3/73 (Vishay) | Same 60V VRRM, 1A IF, but VF = 0.72V max; SOD-123 package (slightly smaller body than SOD-123W). | Compatible in space-constrained designs where 2.7×1.3mm footprint is preferred over 2.9×1.4mm. | Select SS16HE3/73 only if board layout accommodates tighter pad spacing and reduced thermal mass. |
| SB160-TB (ON Semiconductor) | 60V VRRM, 1A IF, VF = 0.75V max; SOD-123 package, no AEC-Q101 qualification. | Limited to industrial or consumer applications lacking automotive reliability requirements. | Choose SB160-TB only for cost-sensitive non-automotive designs where AEC-Q101 is not mandated. |
Compared with SS16HE3/73 and SB160-TB, the SS16LWH uniquely combines AEC-Q101 qualification, SOD-123W's enhanced thermal pad area, and lowest VF (0.70V) in its voltage class-making it optimal for thermally demanding automotive power stages.

FAQ
What is the maximum junction temperature rating for the SS16LWH?
The SS16LWH has a maximum junction temperature (TJ) rating of +150°C, verified per AEC-Q101 stress testing. This allows continuous operation in under-hood automotive environments where ambient temperatures exceed +105°C. The SS16LWH maintains full electrical specifications up to this limit, and thermal design must account for RθJL = 25°C/W to ensure safe operation under 1A load.
Is the SS16LWH pin-compatible with other parts in the SS1xLWH series?
Yes, all SS1xLWH variants-including SS14LWH, SS16LWH, SS110LWH, and SS115LWH-share identical SOD-123W package dimensions, pinout, and mounting footprint. The only differences are VRRM rating (40V–150V) and forward voltage (0.55V–0.95V), allowing direct substitution in layouts designed for any member of the series when voltage and VF requirements align.
Does the SS16LWH meet RoHS and halogen-free compliance standards?
Yes, the SS16LWH is RoHS compliant and halogen-free per IEC 61249-2-21, confirmed in TSC's official documentation. Lead finish is matte tin, and the molding compound meets UL 94V-0 flammability rating. These attributes support environmental compliance in global automotive and industrial product certifications.
What is the marking code printed on the SS16LWH device body?
The SS16LWH is marked with "16LW" on its top surface, consistent with TSC's ordering code convention where "16" denotes 60V VRRM and "LW" identifies the SOD-123W package variant. This marking is visible under standard optical inspection and aligns with JEDEC DO-219 AB labeling requirements.
How does the guard ring feature improve reliability in the SS16LWH?
The guard ring in the SS16LWH enhances edge termination robustness, suppressing premature avalanche breakdown under transient overvoltage conditions such as load dump or ISO 7637-2 pulses. This structural feature increases voltage standoff margin beyond nominal VRRM, reducing field failure rates in automotive power rails without requiring external clamping components.
