Product details
Overview
SA6.0CA-E3/54 from Vishay General Semiconductor is a bidirectional TransZORB® transient voltage suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 500 W peak pulse power (10/1000 μs), 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR at 10 mA), and clamps to ≤10.3 V at 48.5 A peak pulse current.
For engineers reviewing the SA6.0CA-E3/54 datasheet, SA6.0CA-E3/54 pinout, SA6.0CA-E3/54 application, or SA6.0CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification for automotive use, DO-15 mechanical compatibility, low clamping ratio (VC/VBR ≈ 1.49), and 175 °C maximum junction temperature for harsh-environment reliability.
Technical Context
This TVS diode operates symmetrically in both polarities, with identical electrical characteristics forward and reverse - no cathode marking required. Its glass-passivated junction ensures stable breakdown behavior and low leakage (≤600 μA at VWM), while the 10/1000 μs waveform rating reflects standardized surge immunity testing per R.E.A. definitions.
The device delivers 500 W peak pulse power with low incremental surge resistance and fast response time (<1 ns), enabling effective protection of downstream ICs, MOSFETs, and sensor interfaces against ESD, inductive switching spikes, and lightning-induced surges in industrial and automotive systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; sets system-level overvoltage threshold. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown range ensures reliable turn-on margin above VWM. |
| VC @ IPPM | 10.3 V at 48.5 A - Clamping voltage under full-rated surge defines protected circuit's worst-case overvoltage exposure. |
| PPPM | 500 W (10/1000 μs) - Peak surge energy handling capacity compatible with IEC 61000-4-5 Level 4 requirements. |
| IPPM | 48.5 A - Peak surge current capability determines survivability against high-energy transients. |
| TJ max | +175 °C - Enables operation in under-hood automotive or high-ambient industrial environments without derating. |
| Leakage ID | ≤600 μA at VWM - Low standby current avoids loading sensitive signal paths or battery-powered circuits. |

IC Role / Device Role / Timing Role: Placed across DC output rails to clamp transient spikes from transformer leakage inductance or rectifier recovery. Use Value: 6.0 V VWM aligns with 5 V ±10% system rails; low leakage (<600 μA) avoids efficiency loss in standby mode. | Use Scenario: Protecting Ethernet PHY or RS-485 transceivers connected to outdoor cabling subject to lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Bidirectional configuration enables symmetrical clamping on differential pairs without polarity concerns. Use Value: Identical forward/reverse VBR and VC ensure balanced protection on twisted-pair lines, preserving signal integrity during surge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6.0CA | Same VWM, VBR, and PPPM, but in SMC (DO-214AB) surface-mount package; 1.5× smaller footprint, higher thermal resistance. | Preferred for space-constrained PCBs where reflow assembly is used; not suitable for through-hole or high-vibration mechanical mounting. | Select SMA6.0CA when board area is limited and thermal management via copper pour is feasible. |
| P6KE6.8CA | Higher VWM (6.8 V), slightly higher VBR (7.56–8.36 V), same DO-15 package and 500 W rating; older industry-standard series. | Compatible with legacy designs using P6KE family footprints; may require layout review due to 0.8 V higher VWM affecting margin near 5 V rails. | Choose P6KE6.8CA only for drop-in replacement in existing P6KE-based designs; verify VWM margin against system voltage tolerance. |
Compared with SMA6.0CA and P6KE6.8CA, SA6.0CA-E3/54 offers AEC-Q101 qualification and tighter VBR tolerance (±5.3%) in a proven DO-15 through-hole package - making it optimal for new automotive and industrial designs requiring traceable reliability and mechanical robustness.

FAQ
What is the clamping voltage of SA6.0CA-E3/54 at its rated peak pulse current?
The SA6.0CA-E3/54 clamps to a maximum of 10.3 V at its rated peak pulse current of 48.5 A (10/1000 μs waveform). This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The clamping performance is consistent in both directions due to its bidirectional design, and the SA6.0CA-E3/54 maintains this specification across its full operating temperature range.
Is SA6.0CA-E3/54 suitable for automotive applications?
Yes, SA6.0CA-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its 175 °C maximum junction temperature, glass-passivated junction, and DO-15 package with matte tin plating meet stringent automotive reliability requirements. The SA6.0CA-E3/54 is commonly deployed in engine control units, body control modules, and ADAS sensor interfaces where protection against load dump and ISO 7637-2 transients is critical.
Does SA6.0CA-E3/54 have polarity markings on the package?
No, SA6.0CA-E3/54 does not have polarity markings because it is a bidirectional TVS diode. Unlike unidirectional types (which feature a cathode band), the SA6.0CA-E3/54 exhibits identical electrical characteristics in both directions - meaning either lead can serve as anode or cathode depending on transient polarity. This symmetry simplifies layout and eliminates orientation errors during manual or automated assembly.
What is the maximum leakage current of SA6.0CA-E3/54 at its stand-off voltage?
The maximum reverse leakage current (ID) of SA6.0CA-E3/54 is 600 μA at its 6.0 V stand-off voltage (VWM) and 25 °C ambient temperature. This low leakage ensures minimal impact on power-sensitive circuits such as battery-backed sensors or always-on microcontroller inputs. The SA6.0CA-E3/54 maintains acceptable leakage levels even at elevated temperatures, supporting reliable operation in industrial and automotive environments.
How does SA6.0CA-E3/54 compare to unidirectional SA6.0A-E3/54 in terms of circuit protection?
The SA6.0CA-E3/54 provides symmetrical bidirectional clamping, making it ideal for AC-coupled or differential signal lines where polarity reversal occurs - unlike the unidirectional SA6.0A-E3/54, which only clamps in reverse bias and conducts forward current up to 3.5 V. The SA6.0CA-E3/54 eliminates need for external polarity management and supports protection of balanced interfaces like RS-485 or CAN without additional components, whereas SA6.0A-E3/54 requires careful orientation and cannot protect against positive-going transients on the anode side.
