Product details
Overview
SA60CA from Fairchild Semiconductor is a 500 W bidirectional transient voltage suppressor (TVS) diode in DO-15 package, with 60 V reverse stand-off voltage (VRWM), 66.7–73.7 V breakdown voltage (VBR), 96.8 V clamping voltage at peak pulse current, and 5.2 A peak pulse current on 10/1000 μs waveform - used for surge protection in AC power inputs and telecom line interfaces.
For engineers reviewing the SA60CA datasheet, pinout, applications, or equivalent options, key selection criteria include bidirectional clamping capability, low incremental surge resistance, sub-5 ns response time, IR < 1.0 μA at VRWM, and DO-15 mechanical compatibility with legacy PCB footprints.
Technical Context
The SA60CA operates as a bipolar junction TVS device with symmetrical clamping behavior in both directions, enabling robust protection against positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable leakage and long-term reliability under repeated surge stress.
Designed for 10/1000 μs standard surge waveforms per R.E.A., it delivers 500 W peak pulse power with clamping voltage tightly controlled at 96.8 V - critical for safeguarding downstream components like bridge rectifiers, AC-DC controllers, and isolation amplifiers in industrial power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 500 W on 10/1000 μs waveform - defines maximum single-event surge energy absorption capability |
| Reverse Stand-off Voltage | 60 V - maximum continuous operating voltage before significant leakage begins |
| Breakdown Voltage | 66.7–73.7 V at 1.0 mA - onset of avalanche conduction under transient conditions |
| Clamping Voltage | 96.8 V at 5.2 A IPPM - actual voltage seen by protected circuit during rated surge event |
| Peak Pulse Current | 5.2 A on 10/1000 μs waveform - quantifies surge current handling before clamping limit |
| Reverse Leakage | <1.0 μA at 60 V - ensures minimal standby power loss and signal integrity in high-impedance circuits |
| Response Time | <5.0 ns - enables effective suppression of fast-rising ESD and lightning-induced transients |
Pinout & Package
SA60CA is housed in a DO-15 axial-leaded package with no cathode band - consistent with bidirectional construction. Leads are tinned and suitable for wave or hand soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction terminal | No polarity distinction - either lead serves as input/output for transient clamping in AC-coupled paths |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable electrical characteristics and long-term reliability under thermal cycling and humidity stress |
| 500 W peak pulse power rating | Supports IEC 61000-4-5 Level 4 (4 kV line-to-line, 2 Ω source impedance) compliance in AC mains applications |
| Low incremental surge resistance | Minimizes voltage overshoot during high di/dt events, improving protection margin for sensitive ICs |
| Fast response time <5.0 ns | Enables clamping before transient energy couples into downstream filtering or regulation stages |
Applications
| AC Power Input Protection | Telecom Line Interface |
|---|---|
Use Scenario: Installed across AC mains input (L-N or L/N-PE) in industrial power supplies and motor drives to absorb lightning surges and switching transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp protecting bridge rectifier, EMI filter capacitors, and primary-side controller ICs. Use Value: Limits transient voltage to ≤96.8 V, preventing destructive breakdown of 100 V-rated electrolytic capacitors and MOSFETs. | Use Scenario: Placed on tip/ring lines of analog telephone interfaces or DSL front-ends to meet GR-1089-CORE surge immunity requirements. IC Role / Device Role / Timing Role: Bidirectional surge limiter referenced to common-mode ground, suppressing differential and common-mode transients. Use Value: Maintains signal integrity below 60 V DC bias while clamping ±1 kV/0.5 Ω surges to safe levels for SLIC and codec ICs. |
| Industrial Sensor Signal Conditioning | AC Motor Drive Control Board |
Use Scenario: Mounted on 4–20 mA current loop inputs of PLC analog modules exposed to field wiring transients. IC Role / Device Role / Timing Role: Low-leakage (≤1 μA) transient shunt placed ahead of precision op-amps and ADC front-ends. Use Value: Prevents latch-up or offset drift in instrumentation amplifiers during 2 kV EFT bursts without loading the loop. | Use Scenario: Integrated into gate driver supply rails and feedback sensing nodes of 3-phase inverter control boards. IC Role / Device Role / Timing Role: Secondary-level clamping device protecting isolated gate drivers and current-sense amplifiers from cross-talk and shoot-through induced spikes. Use Value: Clamps coupled transients to ≤96.8 V, avoiding false triggering of DESAT protection or ADC saturation in current measurement paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CA | DO-214AA package; same 60 V VRWM and 96.8 V VC, but higher 600 W rating and lower 5.5 A IPPM | Surface-mount footprint; better thermal performance in automated assembly; requires PCB rework for through-hole replacement | Select when board space is constrained and reflow compatibility is required |
| P6KE60CA | DO-15 package; identical VRWM and VC, but lower 500 W rating limited to 1.5 mm lead length derating | Legacy design continuity; same mounting and soldering process; slightly reduced surge margin above 75°C ambient | Select for drop-in replacement in existing DO-15 designs where thermal management is verified |
Compared with SMBJ60CA and P6KE60CA, the SA60CA offers identical clamping performance and DO-15 through-hole compatibility, but with optimized thermal dissipation at 0.375" lead length - making it preferred for high-reliability industrial power entry designs where manual assembly and serviceability are prioritized.

FAQ
What is the clamping voltage of the SA60CA under rated surge conditions?
The SA60CA has a maximum clamping voltage (VC) of 96.8 V at its rated peak pulse current (IPPM) of 5.2 A on a 10/1000 μs waveform. This value is measured per R.E.A. standards and represents the upper voltage limit imposed on protected circuitry during a full-rated transient event. The SA60CA maintains this clamping performance consistently across its operating temperature range, ensuring predictable protection behavior in industrial environments.
Is the SA60CA unidirectional or bidirectional, and how does that affect its use?
The SA60CA is a bidirectional TVS diode, indicated by the "CA" suffix and confirmed by its symmetrical electrical characteristics in both polarities. Unlike unidirectional types, it requires no polarity orientation during placement and protects against both positive and negative transients - making it ideal for AC-coupled circuits such as mains inputs, telecom lines, and differential sensor interfaces. The SA60CA has no cathode band marking, further confirming its bidirectional construction.
What is the maximum operating junction temperature for the SA60CA?
The SA60CA has a maximum operating junction temperature (TJ) of +175°C, as specified in Fairchild's Absolute Maximum Ratings table. This high TJ rating supports reliable operation in enclosed industrial enclosures or near heat-generating components like transformers and power semiconductors. Derating curves in the SA60CA datasheet confirm usable power dissipation up to this limit when lead length and ambient conditions comply with the 0.375" lead specification.
Does the SA60CA meet industry-standard surge immunity requirements?
Yes, the SA60CA's 500 W peak pulse power rating and 96.8 V clamping voltage enable compliance with IEC 61000-4-5 Level 4 (4 kV line-to-line, 2 Ω source) when properly integrated with series impedance and filtering. Its <5.0 ns response time and low leakage (<1.0 μA at 60 V) also support IEC 61000-4-2 ESD and IEC 61000-4-4 EFT requirements in AC input and telecom port designs using the SA60CA.
How does the SA60CA compare to the P6KE60CA in terms of surge handling?
The SA60CA and P6KE60CA share identical VRWM (60 V), VBR (66.7–73.7 V), and VC (96.8 V), but differ in thermal rating methodology: the SA60CA specifies 500 W at 0.375" lead length and 75°C ambient, while the P6KE60CA rates 500 W at shorter leads and tighter derating. In practice, the SA60CA delivers more consistent surge margin in real-world through-hole layouts with standard lead forms, making it preferable for new industrial designs where thermal validation is critical. Both parts remain functionally interchangeable in legacy P6KE60CA sockets.
