Product details
Overview
SA5.0CA from Taiwan Semiconductor is a bidirectional 500W transient voltage suppressor (TVS) diode in DO-204AC (DO-15) package, with 5.0V working stand-off voltage, 6.4–7.3V breakdown voltage at 10mA test current, and 54.0V clamping voltage at 600A peak pulse current. It protects automotive and industrial power rails against ESD, EFT, and inductive switching transients.
For engineers reviewing the SA5.0CA datasheet, SA5.0CA pinout, SA5.0CA application, or SA5.0CA equivalent, this page delivers verified electrical parameters, bidirectional TVS behavior, DO-15 terminal polarity marking, clamping performance under 10/1000μs surge, and AEC-Q101-qualified alternatives for automotive-grade system protection design.
Technical Context
The SA5.0CA operates as a bidirectional avalanche diode, symmetrically clamping voltage surges in both polarities with identical VBR (6.4–7.3V), IPPM (600A), and VC (54.0V) specifications. Its low dynamic impedance enables rapid energy diversion during fast transients.
Designed for unclamped inductive load switching and IEC 61000-4-2/4-4/4-5 compliance, it features <1.0ps response time for unidirectional mode and 5.0ns for bidirectional operation, with reverse leakage <1μA at 5.0V and junction temperature range of –55°C to +175°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous DC or RMS voltage the device blocks without conduction |
| VBR @ IT=10mA | 6.4–7.3 V - Breakdown voltage threshold where avalanche conduction begins, defining minimum surge trigger level |
| VC @ IPPM=600A | 54.0 V - Clamped voltage during 10/1000μs surge, limiting downstream IC stress to safe levels |
| PPK | 500 W - Peak pulse power handling capability per single non-repetitive 10/1000μs waveform |
| IR @ VWM | <1 μA - Reverse leakage current at working voltage, ensuring minimal standby power loss |
| Junction Temp Range | –55°C to +175°C - Operating temperature envelope supporting under-hood automotive and industrial environments |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case with UL 94V-0 rating; cathode band marking denotes polarity for unidirectional variants - SA5.0CA is bidirectional and lacks cathode band; terminals are pure tin-plated for J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Surge return path (bidirectional) | Acts as cathode during positive transients and anode during negative transients; symmetrical conduction |
| Cathode | Surge return path (bidirectional) | Acts as anode during positive transients and cathode during negative transients; no polarity marking required |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR, VC, and IPPM in both directions - eliminates need for dual-device placement in AC or floating bus protection |
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics - meets stress testing for temperature cycling, HTRB, and ESD |
| Fast transient response | 5.0 ns response time from 0 V to VBR - ensures clamping activation before sensitive logic or analog circuitry sustains damage |
| Low clamping ratio | VC/VBR ≈ 7.5 - high efficiency in voltage limiting relative to breakdown threshold, reducing overvoltage margin design overhead |
Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protecting 5V CAN transceiver power supply against load dump and jump-start transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed between VCC and GND, absorbing ±100V/500W spikes within 5ns. Use Value: Prevents latch-up or permanent damage to CAN PHY ICs by holding rail voltage ≤54.0V during 600A surge events. | Use Scenario: Safeguarding 24V digital input channels on programmable logic controllers exposed to relay coil flyback and EFT bursts. IC Role / Device Role / Timing Role: Standoff protector across input terminal and common, triggered only above 6.4V while leaking <1μA at nominal 24V. Use Value: Enables robust immunity to IEC 61000-4-4 (EFT) without degrading signal integrity or increasing quiescent current. |
| LED Driver Surge Suppression | USB Port ESD Protection |
Use Scenario: Shielding constant-current LED driver ICs from inductive kickback when driving high-side MOSFETs in automotive lighting modules. IC Role / Device Role / Timing Role: Parallel-connected TVS across driver output and ground, clamping flyback spikes before they reach gate drivers or current sense amplifiers. Use Value: Maintains LED string reliability by limiting transient overshoot to 54.0V, well below 60V absolute maximum ratings of typical LED drivers. | Use Scenario: Providing secondary-level ESD protection on USB 2.0 VBUS lines in embedded host devices operating in harsh industrial environments. IC Role / Device Role / Timing Role: Low-capacitance (<100pF) bidirectional clamp shunting VBUS to GND during ±8kV contact discharge per IEC 61000-4-2. Use Value: Complements primary TVS arrays by handling residual surges that bypass front-end filters, with sub-μA leakage preserving USB suspend current budgets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Unidirectional; requires external series resistor or dual-device configuration for bidirectional protection; 5.0V VWM, 6.4–7.0V VBR, 9.2V VC @ 600A | Limited to DC-biased rails; unsuitable for AC-coupled or floating nodes without redesign | Select SMAJ5.0A only if polarity is fixed and board space allows discrete directional layout |
| 1.5KE5.0CA | Same DO-15 package and bidirectional function; higher PPK = 1500W but larger VC = 9.6V @ 100A (not 600A); lower IPPM derating above 25°C | Better for lower-current, higher-energy pulses; less effective for fast 600A transients due to thermal inertia | Choose 1.5KE5.0CA when surge duration exceeds 1ms or when peak current is ≤100A |
Compared with SMAJ5.0A and 1.5KE5.0CA, the SA5.0CA uniquely delivers bidirectional 600A clamping at 54.0V in DO-15 with AEC-Q101 qualification - enabling single-device, automotive-grade protection without polarity constraints or layout compromise.

FAQ
What is the clamping voltage of SA5.0CA at its rated peak pulse current?
The SA5.0CA clamps to 54.0 V at 600 A peak pulse current under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the maximum voltage imposed on protected circuitry during worst-case surge events. The SA5.0CA maintains this clamping performance symmetrically in both directions due to its bidirectional construction.
Is SA5.0CA qualified for automotive applications?
Yes, SA5.0CA is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias, temperature cycling, and ESD per JESD22-A114. This qualification confirms suitability for automotive powertrain, body control, and infotainment systems where reliability under thermal and electrical stress is critical. The SA5.0CA datasheet explicitly lists AEC-Q101 availability for the CA suffix variant.
How does SA5.0CA differ from SA5.0A?
The SA5.0CA is bidirectional, while SA5.0A is unidirectional. SA5.0CA provides symmetrical clamping in both polarities with identical VBR (6.4–7.3 V) and VC (54.0 V) values, whereas SA5.0A clamps only in reverse direction and has VC = 57.0 V. Both share DO-204AC packaging and 500 W rating, but SA5.0CA eliminates need for polarity-aware layout or dual-diode configurations.
What is the maximum operating temperature for SA5.0CA?
The SA5.0CA has a maximum junction temperature (TJ) of +175°C and a storage temperature range of –55°C to +175°C. This wide thermal envelope supports deployment in under-hood automotive locations and industrial enclosures without derating up to 125°C ambient, provided PCB copper pad area and airflow meet TSC's thermal guidelines for DO-204AC mounting.
Does SA5.0CA have a polarity marking on the package?
No, SA5.0CA does not feature a cathode band or other polarity marking because it is a bidirectional TVS diode. Unlike unidirectional SA5.0 or SA5.0A variants, the SA5.0CA conducts identically in both directions and is marked only with part-specific date code and factory identifiers per TSC's DO-204AC marking diagram. Physical orientation during placement has no electrical effect.
