Product details
Overview
SA6.0ARL from ON Semiconductor is a unidirectional 500 W peak power MiniMOSORB Zener transient voltage suppressor (TVS) designed for clamping high-energy transients in DC power rails and signal lines. It features a 6.0 V working peak reverse voltage (VRWM), 10.3 V maximum clamping voltage at 48.5 A peak pulse current, <1.0 ns response time, and UL 497B recognition for isolated loop circuit protection.
For engineers reviewing the SA6.0ARL datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM matching system operating voltage, clamping voltage margin relative to protected IC's absolute maximum rating, surge current capability under 1 ms pulses, thermal derating above 75°C lead temperature, and axial lead (Case 59AA) mounting compatibility with through-hole PCB layouts.
Technical Context
The SA6.0ARL operates as a voltage-clamping device that remains high-impedance below VRWM = 6.0 V and rapidly avalanches above its breakdown voltage (VBR = 6.67–7.37 V @ IT = 10 mA) to limit transient overvoltage. Its low zener impedance and fast <1.0 ns response ensure effective suppression of ESD and lightning-induced surges before sensitive downstream components are stressed.
It is rated for 500 W nonrepetitive peak pulse power per 1.0 ms waveform (Figure 4), with steady-state power dissipation limited to 3.0 W at TL ≤ 75°C and derated linearly beyond. Thermal resistance from junction-to-lead is 33.3°C/W, supporting reliable operation in industrial ambient conditions up to +175°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; must exceed system DC rail or signal swing. |
| VBR @ IT=10 mA | 6.67–7.37 V - Breakdown threshold range; defines onset of avalanche conduction under standardized test current. |
| VC @ IPP=48.5 A | 10.3 V - Maximum clamped voltage during 1 ms transient; determines worst-case overvoltage seen by protected circuitry. |
| PPK | 500 W - Peak pulse power handling per single 1 ms event; defines surge energy absorption capacity. |
| Response Time | <1.0 ns - Time from transient rise to clamping onset; ensures protection before logic-level or analog ICs experience overstress. |
| IR @ VRWM | 600 µA - Reverse leakage at rated working voltage; low enough to avoid loading 5 V or 3.3 V supply rails. |
| UL 497B | Recognized - Certified for isolated loop circuit protection; validates compliance for telecom and industrial interface safety requirements. |
Pinout & Package
SA6.0ARL is housed in an axial-leaded Surmetic plastic package (Case 59AA), with cathode identified by a polarity band. Leads are tin-plated, solderable, and rated for 260°C for 10 seconds at 1/16 inch from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes clamping path during reverse transient. |
| Cathode | High-side transient input | Connected to protected line (e.g., VBUS, RS-485 A/B); carries full surge current into anode during clamping. |
Key Features
| Feature | Design Value |
|---|---|
| 500 W peak pulse power | Enables robust protection against IEC 61000-4-5 Level 4 (4 kV/2 Ω) surges without degradation. |
| Clamping voltage ≤10.3 V @ 48.5 A | Provides safe margin below 12 V logic IC absolute maximum ratings and avoids latch-up in microcontrollers. |
| ESD rating >16 kV HBM | Meets IEC 61000-4-2 Level 4 contact discharge requirements for front-panel and connector interfaces. |
| UL 497B recognition | Validates suitability for certified isolated data/power interfaces in medical and industrial equipment. |
| Lead temperature rating 260°C | Supports standard wave and reflow soldering processes without package damage or parameter shift. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A | Surface-mount SMA package (vs. axial Case 59AA); same VRWM (6.0 V) but higher VC = 10.5 V @ 43.4 A. | Requires SMT layout change; better suited for space-constrained PCBs with automated assembly. | Select when board real estate is limited and reflow compatibility is required over through-hole serviceability. |
| P6KE6.8A | DO-15 package; VRWM = 6.8 V (higher hold-off), VC = 11.2 V @ 44.6 A, lower PPK = 600 W but slower response (~1.5 ns). | Marginally higher clamping voltage reduces protection margin for 5 V logic; used in legacy industrial designs. | Choose only if VRWM ≥6.8 V matches system voltage tolerance and layout reuse of DO-15 footprint is critical. |
Compared with SMAJ6.0A and P6KE6.8A, SA6.0ARL offers the lowest clamping voltage (10.3 V) in an axial package optimized for manual assembly, high-reliability leaded mounting, and UL 497B-certified isolated loop use-making it preferred for medical and industrial field-serviceable equipment.

FAQ
What is the working peak reverse voltage (VRWM) of the SA6.0ARL?
The SA6.0ARL has a VRWM of 6.0 V, meaning it remains non-conductive up to this DC or continuous peak reverse voltage. This value is selected to match nominal 5 V systems while providing margin above typical rail tolerances. Exceeding VRWM initiates avalanche clamping, and the SA6.0ARL is rated to sustain this condition only during transient events-not continuously.
Does the SA6.0ARL meet UL 497B certification?
Yes, the SA6.0ARL is explicitly included in ON Semiconductor's UL 497B recognition (File #E116110, QVGV2 category) for isolated loop circuit protection. This certification covers dielectric withstand, endurance conditioning, and strike voltage breakdown testing-validating its use in safety-critical telecom and medical interfaces where isolation barrier integrity is mandated.
What is the maximum clamping voltage of the SA6.0ARL and at what current is it specified?
The SA6.0ARL has a maximum clamping voltage (VC) of 10.3 V, measured at a peak pulse current (IPP) of 48.5 A using the 1.0 ms exponential waveform defined in Figure 4 of the datasheet. This VC value represents the worst-case voltage imposed on protected circuitry during a full-rated surge event and is critical for ensuring downstream ICs remain within their absolute maximum voltage ratings.
Is the SA6.0ARL RoHS-compliant and Pb-free?
Yes, the "RLG" suffix in SA6.0ARL indicates a Pb-free axial leaded package compliant with RoHS Directive 2011/65/EU. The device uses matte tin-plated leads and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), with no special floor life handling required prior to soldering.
What is the thermal resistance and steady-state power rating of the SA6.0ARL?
The SA6.0ARL has a junction-to-lead thermal resistance (RJL) of 33.3°C/W and a steady-state power dissipation (PD) of 3.0 W at lead temperature (TL) ≤75°C. Above 75°C, PD derates linearly at 30 mW/°C, reaching zero at TL = 175°C. This thermal profile supports reliable operation in enclosed industrial enclosures with passive heatsinking via PCB copper pour or chassis mounting.
