Product details
Overview
SA10CA-T from Diodes Incorporated is a bi-directional 500W transient voltage suppressor (TVS) diode in DO-15 package, with 10V reverse standoff voltage (VR), 11.1–12.3V breakdown voltage (VBR), 17.0V max clamping voltage (VC) at 29.4A peak pulse current (IPP), and −65°C to +175°C operating temperature range. It protects DC power rails and signal lines in industrial motor drives against ESD and lightning-induced surges.
For engineers reviewing the SA10CA-T datasheet, SA10CA-T pinout, SA10CA-T application, or SA10CA-T equivalent, key selection criteria include bidirectional clamping capability, 17.0V clamping under 29.4A 10/1000µs surge, DO-15 mechanical compatibility, RoHS-compliant matte tin plating, and derating behavior above 25°C ambient.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, enabling protection of AC-coupled or floating signal paths without polarity dependency. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<3.0mA @ VR), critical for high-impedance sensor interfaces.
The device uses a 10/1000µs double-exponential surge waveform per R.E.A. standards, delivering 500W non-repetitive peak pulse power at TL = 75°C with 9.5mm lead length. Thermal derating begins linearly above 25°C ambient, reaching 50% power capability at 125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 500 W - sustains single 10/1000µs surge events without failure |
| Reverse Standoff Voltage (VR) | 10 V - maximum continuous working voltage before clamping initiates |
| Breakdown Voltage (VBR) | 11.1–12.3 V @ 1.0 mA - precise conduction threshold with ±5% tolerance |
| Clamping Voltage (VC) | 17.0 V @ 29.4 A - limits downstream voltage stress during worst-case surge |
| Peak Pulse Current (IPP) | 29.4 A - maximum surge current handled at rated clamping voltage |
| Operating Temperature | −65°C to +175°C - supports under-hood automotive and industrial environments |
| Leakage Current (IR) | ≤3.0 mA @ 10 V - minimal standby power loss in battery-powered systems |
Pinout & Package
DO-15 molded plastic package (UL 94V-0), axial-leaded, 9.5 mm lead length, 0.4 g mass. Cathode band omitted for bi-directional configuration; marking consists of "SA10CA" only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional surge path | No polarity sensitivity - connects across protected line and ground (or between differential lines) |
| Leads (both) | Thermal & electrical interface | Plated for solderability per MIL-STD-202; 9.5 mm length defines thermal resistance to PCB |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures long-term VBR stability and reduced parameter drift over temperature cycling |
| Bi-directional clamping | Protects AC signals, RS-485 buses, and transformer-coupled interfaces without external polarity management |
| RoHS-compliant matte tin plating | Enables lead-free reflow assembly while maintaining solder wetting and intermetallic reliability |
| Fast response time | Sub-nanosecond turn-on enables suppression before sensitive ICs experience overvoltage damage |
Applications
| Industrial Motor Drives | RS-485 Communication Lines |
|---|---|
Use Scenario: Protection of gate driver supply rails against inductive kickback from IGBT switching. IC Role / Device Role / Timing Role: Bidirectional TVS placed between VDD and GND to clamp transients exceeding 10V. Use Value: Limits rail voltage to ≤17.0V during 29.4A surges, preventing latch-up in isolated DC-DC controllers. | Use Scenario: Surge protection on differential A/B lines of factory-floor RS-485 networks exposed to EFT. IC Role / Device Role / Timing Role: Bi-directional clamping device connected line-to-line and line-to-ground. Use Value: Maintains signal integrity by suppressing ±1kV EFT pulses without adding capacitance (>50pF) that degrades 10 Mbps data rate. |
| AC-DC Adapter Inputs | Automotive Body Control Modules |
Use Scenario: Secondary-side overvoltage protection after bridge rectifier in offline SMPS. IC Role / Device Role / Timing Role: Parallel-connected TVS across bulk capacitor to absorb line-induced spikes. Use Value: Clamps 500W surges without thermal runaway, supporting 100% duty-cycle derating up to 75°C board temperature. | Use Scenario: CAN bus power line protection in BCMs subjected to load dump per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Bidirectional clamp on 12V supply rail feeding CAN transceivers. Use Value: Withstands 35V/100ms load dump events by limiting rail excursion to ≤17.0V during fast-rising transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P6KE10CA | Same 10V VR and bi-directional function; 600W peak power; larger DO-15 variant with higher IPP (32.5A) | Higher surge margin suits 24V industrial PLC backplanes with frequent switching noise | Select when system-level surge testing exceeds IEC 61000-4-5 Level 4 (4kV) |
| SMAJ10CA | Surface-mount SMA package; same 10V VR; lower 400W peak power; 27.8A IPP; 17.0V VC | Designed for space-constrained PCB layouts where through-hole DO-15 is impractical | Choose for automated SMT assembly and compact consumer electronics enclosures |
Compared with SA10CA-T, P6KE10CA offers higher surge robustness in identical through-hole form factor, while SMAJ10CA trades power rating for board-space savings and reflow compatibility-neither is pin-compatible due to differing package geometries and thermal paths.

FAQ
What does the "-T" suffix indicate in SA10CA-T?
The "-T" suffix denotes tape-and-reel packaging: 4,000 units per 13-inch reel, optimized for automated SMT placement equipment. This differs from "-B" (bulk packaging) and confirms RoHS compliance per EU Directive Annex Notes 5 and 7, with matte tin plating meeting J-STD-020C Level 1 moisture sensitivity requirements.
Is SA10CA-T suitable for new designs despite the "Not Recommended" note?
No-Diodes Incorporated explicitly marks the SAxxA/SAxxCA family as "NOT RECOMMENDED FOR NEW DESIGN" in DS21501 Rev. 12, citing obsolescence trajectory and recommending P6KE6V8A–P6KE200A as replacements. SA10CA-T remains available for legacy repair and continuity builds but lacks long-term roadmap support.
How does SA10CA-T differ from unidirectional SA10A-T?
SA10CA-T is bi-directional (no cathode band, symmetrical clamping), while SA10A-T is unidirectional (cathode-banded, conducts only in reverse bias). Their VBR (11.1–12.3V), VC (17.0V), and IPP (29.4A) are identical, but SA10A-T cannot protect AC or floating nodes without additional circuitry.
Can SA10CA-T be used in place of a Zener diode for voltage regulation?
No-SA10CA-T is designed exclusively for transient suppression, not steady-state regulation. Its 3.0mA IR at 10V and lack of tight VZ tolerance make it unsuitable for precision reference or shunt regulation; it conducts heavily only during surges and exhibits no controlled forward conduction like a Zener.
