Product details
Overview
SA6V0CA from Fairchild Semiconductor is a 500 W bidirectional transient voltage suppressor (TVS) diode in DO-15 package, designed for clamping ESD and surge transients in power and signal lines. It features a 6.0 V reverse stand-off voltage (VRWM), 6.67–7.37 V breakdown voltage (VBR), 10.3 V clamping voltage at 48.5 A peak pulse current (IPPM), and operates up to +175 °C junction temperature.
For engineers reviewing the SA6V0CA datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, bidirectional clamping behavior, thermal derating curves, DO-15 mechanical interface details, and direct alternatives for industrial power supply protection, automotive body electronics, and telecom interface surge hardening.
Technical Context
The SA6V0CA is a glass-passivated, bidirectional TVS diode optimized for unidirectional and bidirectional transient suppression on DC power rails and AC-coupled signal paths. Its low incremental surge resistance and sub-5 ns response time ensure fast clamping during lightning-induced surges or inductive switching events.
It complies with IEC 61000-4-2 (ESD) and IEC 61000-4-5 (surge) immunity standards when applied with appropriate PCB layout and series impedance. Electrical characteristics-including VRWM, VBR, VC, and IPPM-are specified under standardized 10/1000 μs waveform conditions and validated across -65 °C to +175 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 500 W on 10/1000 μs waveform - supports high-energy surge events without failure |
| Reverse Stand-off Voltage | 6.0 V - maximum continuous DC or RMS voltage before significant leakage |
| Breakdown Voltage | 6.67–7.37 V at 10 mA - defines onset of avalanche conduction under transient stress |
| Clamping Voltage | 10.3 V at 48.5 A IPPM - limits downstream circuit voltage during worst-case surge |
| Peak Pulse Current | 48.5 A on 10/1000 μs waveform - quantifies maximum transient energy absorption capability |
| Reverse Leakage | <600 μA at VRWM - ensures minimal quiescent power loss in standby operation |
| Junction Temperature | +175 °C max - enables use in under-hood automotive or high-ambient industrial environments |
Pinout & Package
SA6V0CA is housed in a DO-15 axial-leaded package with no polarity marking-consistent with its bidirectional function. Leads are tinned copper, rated for 0.375" lead length at 75 °C ambient for 1.0 W steady-state dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | No cathode band; terminals interchangeable - clamps positive and negative transients equally |
| Lead 1 / Lead 2 | Current path during surge | Both leads conduct identically in either direction; no internal rectification or asymmetry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J6.0A | Surface-mount SMA package; same 6.0 V VRWM, but lower 600 W rating and 52.2 A IPPM | Requires PCB redesign; better suited for space-constrained consumer electronics | Select when board area is limited and reflow assembly is preferred over through-hole |
| P6KE6.0CA | Same DO-15 package and bidirectional function; 600 W rating, 52.2 A IPPM, 10.5 V VC | Nearly identical performance; minor VC difference (10.5 V vs. 10.3 V) has negligible system impact | Preferred for second-source procurement where Fairchild supply continuity is a concern |
Compared with SA6V0CA, SMA6J6.0A offers SMT compatibility at the cost of higher mounting complexity and reduced thermal mass, while P6KE6.0CA provides identical form-factor redundancy with virtually identical clamping behavior-making it the most seamless alternative for existing DO-15 layouts.

FAQ
What is the clamping voltage of SA6V0CA at its rated peak pulse current?
The SA6V0CA exhibits a maximum clamping voltage (VC) of 10.3 V when subjected to its rated peak pulse current (IPPM) of 48.5 A under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and guarantees predictable overvoltage limiting for downstream circuitry. The SA6V0CA's low VC directly enables compatibility with 12 V systems where rail integrity must be preserved during surge events.
Is SA6V0CA unidirectional or bidirectional, and how is polarity identified?
SA6V0CA is a bidirectional TVS diode, indicated by the "CA" suffix per Fairchild's naming convention. Unlike unidirectional variants (e.g., SA6V0A), it has no cathode band and functions identically for positive and negative transients. This eliminates orientation concerns during manual or automated assembly and simplifies design for AC-coupled or floating-rail applications. The SA6V0CA's symmetrical IV curve is confirmed in the Electrical Characteristics table.
What is the maximum operating junction temperature for SA6V0CA?
The SA6V0CA is rated for a maximum operating junction temperature (TJ) of +175 °C, enabling reliable operation in high-ambient environments such as engine compartments, industrial motor drives, and enclosed power supplies. This rating is validated per Absolute Maximum Ratings and aligns with its glass-passivated construction. Derating curves in the datasheet confirm sustained performance up to this limit when mounted with 0.375" lead length at 75 °C ambient.
Can SA6V0CA replace SA6V0A in an existing design?
No-SA6V0CA and SA6V0A are not interchangeable without circuit review. SA6V0A is unidirectional with a cathode band and only clamps positive transients, whereas SA6V0CA is bidirectional with no polarity marking. Substituting SA6V0CA for SA6V0A may cause unintended conduction in DC-biased circuits. The SA6V0CA is intended for applications requiring symmetrical clamping, not as a drop-in replacement for unidirectional variants.
What industry standards does SA6V0CA support for surge immunity testing?
The SA6V0CA's 500 W peak pulse rating and 48.5 A IPPM enable compliance with key surge immunity standards including IEC 61000-4-5 (Level 4, 4 kV/2 Ω line-earth) and IEC 61000-4-2 (±15 kV air, ±8 kV contact ESD) when implemented with proper PCB layout and series impedance. Its fast response time (<5 ns) and low clamping voltage ensure effective protection for systems targeting EN 55032, CISPR 25, and ISO 16750-2 certification. The SA6V0CA itself is not certified, but its parameters meet these test requirements.
