Product details
Overview
SS16H from Taiwan Semiconductor is a 1A, 60V Schottky barrier surface-mount rectifier in DO-214AC (SMA) package, featuring low forward voltage (0.75 V at 1 A, 25°C), high surge current capability (40 A), and AEC-Q101 qualification for automotive use. It serves as a freewheeling or reverse-battery protection diode in DC/DC converters and car lighting systems.
For engineers reviewing the SS16H datasheet, SS16H pinout, SS16H application, or SS16H equivalent, key selection criteria include its 60 V repetitive peak reverse voltage, 0.75 V forward voltage at 1 A and 25°C, 40 A non-repetitive surge rating, -55°C to +150°C junction temperature range, and DO-214AC mechanical compatibility with automated SMT placement.
Technical Context
The SS16H is a single-die Schottky rectifier optimized for low-loss operation in high-frequency switching applications. Its guard ring structure provides overvoltage protection, and its matte tin-plated leads meet J-STD-002 solderability requirements.
Thermal performance is defined by a junction-to-lead resistance of 28°C/W and junction-to-ambient resistance of 88°C/W. It complies with JESD201 Class 2 whisker testing and moisture sensitivity level 1 per J-STD-020.

Applications
| DC/DC Converter Output Rectification | Reverse Battery Protection |
|---|---|
Use Scenario: Used in secondary-side synchronous or asynchronous rectification of 5–24 V isolated or non-isolated buck converters in ADAS ECUs. IC Role / Device Role / Timing Role: Schottky rectifier providing unidirectional current path with minimal conduction loss during on-state. Use Value: 0.75 V forward drop at 1 A reduces power dissipation by ~30% vs. comparable silicon diodes, lowering thermal load on small PCB areas. | Use Scenario: Placed in series with vehicle battery feed to prevent damage during accidental reverse connection in infotainment head units. IC Role / Device Role / Timing Role: Unidirectional blocking element that conducts only when battery polarity is correct. Use Value: 60 V VRRM withstands load dump transients up to ISO 7637-2 Pulse 5a, while 40 A IFSM handles cranking surges. |
| Automotive LED Lighting Driver | Freewheeling Diode in Motor Control |
Use Scenario: Freewheeling path in constant-current LED driver ICs powering exterior lamps (tail, brake, DRL) in 12 V systems. IC Role / Device Role / Timing Role: Provides low-loss recirculation path for inductor current during PWM off-time. Use Value: Low VF minimizes voltage headroom loss, enabling full brightness at low input voltages (e.g., 9 V cranking). | Use Scenario: Clamp diode across brushed DC motor windings in seat/mirror actuators to suppress inductive kick. IC Role / Device Role / Timing Role: Fast-recovery freewheeling element absorbing stored magnetic energy during MOSFET turn-off. Use Value: Schottky architecture ensures <10 ns recovery time, eliminating voltage overshoot spikes that could damage gate drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS1L60S | Same 1 A / 60 V rating; VF = 0.72 V @ 1 A, 25°C; DO-214AC package; no AEC-Q101 claim in datasheet | Not certified for automotive use; suitable for industrial or consumer DC/DC where qualification isn't mandated | Select when cost sensitivity outweighs automotive qualification requirement |
| SB160-E3/54 | 1 A / 60 V; VF = 0.75 V @ 1 A, 25°C; same DO-214AC; AEC-Q101 qualified; RθJA = 90°C/W (vs. 88°C/W for SS16H) | Identical functional scope; minor thermal margin difference negligible in typical 1-layer PCB layouts | Drop-in alternative where Vishay sourcing is preferred; identical electrical and mechanical interface |
Compared with STPS1L60S and SB160-E3/54, the SS16H offers AEC-Q101 validation plus marginally better thermal resistance (88°C/W), making it optimal for thermally constrained automotive modules requiring long-term reliability under cyclic thermal stress.

FAQ
What is the maximum junction temperature rating for the SS16H?
The SS16H has a maximum junction temperature (TJ) rating of +150°C, verified per AEC-Q101 stress testing. This allows uninterrupted operation in under-hood automotive applications such as engine control modules or headlight drivers where ambient temperatures exceed 105°C. The SS16H maintains specified electrical parameters up to this limit, and its thermal resistance values (RθJL = 28°C/W, RθJA = 88°C/W) enable accurate thermal modeling in PCB layout. Always verify board-level thermal performance using actual power dissipation and copper area.
Is the SS16H suitable for reverse battery protection in 12 V automotive systems?
Yes, the SS16H is explicitly designed for reverse battery protection in 12 V automotive systems. With a 60 V VRRM, it safely blocks reverse polarity while conducting forward current up to 1 A. Its 40 A IFSM rating handles cranking surges and load dump transients per ISO 7637-2, and AEC-Q101 qualification confirms reliability under automotive environmental stresses. The cathode band marking ensures correct orientation during automated placement, and its DO-214AC footprint fits standard SMT workflows used in Tier 1 ECU manufacturing.
What is the forward voltage of the SS16H at elevated temperature?
At 1 A forward current and 100°C junction temperature, the SS16H exhibits a typical forward voltage of 0.65 V - lower than its 25°C value of 0.75 V due to the negative temperature coefficient of Schottky diodes. This behavior improves efficiency in thermally stressed conditions, such as enclosed LED driver enclosures or high-ambient under-dash locations. The datasheet specifies this value under pulse test conditions (PW = 0.3 ms), ensuring relevance to real-world switching regulator operation.
Does the SS16H have halogen-free and RoHS compliance documentation?
Yes, the SS16H is both halogen-free and RoHS compliant, as confirmed in the official Taiwan Semiconductor datasheet (Version B2305). Compliance is verified per EU Directive 2011/65/EU and IPC-4101D/121 standards. The device uses green molding compound and matte tin-plated leads, with full material declarations available upon request from Aetrix Electronics. These certifications support sustainability goals and regulatory acceptance in global automotive and industrial markets.
How does the SS16H compare to the SS15H in terms of electrical performance?
The SS16H and SS15H share identical package (DO-214AC), current rating (1 A), and thermal specs, but differ in peak reverse voltage: SS15H is rated at 50 V, while SS16H is rated at 60 V. Their forward voltage is identical (0.75 V @ 1 A, 25°C), and both exhibit 200 µA reverse leakage at rated VR and 25°C. The SS16H's higher VRRM makes it preferable for 48 V mild-hybrid architectures or 36 V industrial supplies where 50 V margin is insufficient. No PCB or layout changes are needed when upgrading from SS15H to SS16H.
