Product details
Overview
SA6.0A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for circuit protection against ESD and surge transients. It features 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 48.5 V clamping voltage (VC) at 600 A peak pulse current, and 500 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the SA6.0A-E3/54 datasheet, SA6.0A-E3/54 pinout, SA6.0A-E3/54 application, or SA6.0A-E3/54 equivalent, key selection factors include its unidirectional polarity, DO-15 mechanical compatibility, AEC-Q101 qualification (via HE3 variant), 175 °C max junction temperature, and 600 A surge current capability under standardized transient conditions.
Technical Context
The SA6.0A-E3/54 operates as a silicon avalanche diode that enters controlled breakdown above its 6.0 V stand-off threshold to clamp transient overvoltages. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1 ns), enabling protection of downstream ICs and MOSFETs from inductive switching spikes and lightning-induced surges.
It is rated for 500 W peak pulse power (10/1000 μs), 3.0 W steady-state power dissipation on infinite heatsink at 75 °C, and supports 70 A non-repetitive forward surge current (10 ms half-sine). The device complies with JESD22-B106 (solder dip) and JESD201 Class 1A whisker testing (E3 suffix).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed avalanche onset range defining reliable turn-on threshold |
| VC @ IPPM | 48.5 V at 600 A - Clamped voltage during worst-case 10/1000 μs surge, limiting stress on protected circuitry |
| PPPM | 500 W - Peak transient energy absorption capacity per single pulse, critical for automotive load-dump immunity |
| IPPM | 600 A - Maximum non-repetitive surge current the device sustains without failure under standard waveform |
| TJ max | +175 °C - Enables operation in under-hood automotive environments and industrial power supplies |

|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load-dump transients up to 35 V and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground to clamp surges before they reach LDOs and microcontrollers. Use Value: Limits clamped voltage to 48.5 V at 600 A, preserving system uptime and preventing latch-up in downstream logic. | Use Scenario: Shielding analog sensor outputs (e.g., pressure or temperature sensors) from ESD events and cable discharge. IC Role / Device Role / Timing Role: Low-leakage (≤1.0 μA) TVS connected across differential signal pair to suppress ±8 kV contact ESD per IEC 61000-4-2. Use Value: Maintains signal fidelity with sub-μA leakage and <1 ns response, avoiding DC offset or noise injection into precision ADC front-ends. |
| Consumer USB Port Surge Suppression | Telecom Line Card Overvoltage Protection |
Use Scenario: Safeguarding USB 2.0 data lines and VBUS against hot-plug transients and nearby lightning-induced coupling. IC Role / Device Role / Timing Role: Discrete unidirectional TVS on VBUS rail and bidirectional variants on D+/D− lines (e.g., SA6.0CA). Use Value: Withstands 600 A surge while holding clamping voltage below 48.5 V, preventing damage to USB controller PHY and maintaining enumeration robustness. | Use Scenario: Protecting Ethernet PHY interfaces and POTS line drivers from induced surges on outdoor telecom wiring. IC Role / Device Role / Timing Role: Primary-level TVS on tip/ring lines upstream of isolation transformers and secondary protection devices. Use Value: 500 W pulse rating and 175 °C junction rating ensure survivability in uncontrolled environmental enclosures with limited airflow. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A | Same VWM (6.0 V), lower PPPM (400 W), SMA package (surface-mount) | Requires PCB redesign for SMT layout; unsuitable for through-hole legacy designs | Select SMAJ6.0A only when board space constraints mandate surface-mount and surge energy is ≤400 W |
| P6KE6.8A | Higher VWM (6.8 V), same DO-15 package, 600 W rating, but wider VBR tolerance (6.45–7.14 V) | Less precise clamping onset; may allow higher transient voltage before activation | Choose P6KE6.8A if design tolerates 0.8 V higher stand-off and requires broader vendor availability |
Compared with SMAJ6.0A and P6KE6.8A, the SA6.0A-E3/54 offers tighter VBR (6.67–7.37 V), guaranteed DO-15 through-hole compatibility, and RoHS-compliant E3 termination-making it optimal for cost-sensitive, high-volume automotive and industrial through-hole assemblies requiring repeatable clamping behavior.

FAQ
What is the maximum clamping voltage of the SA6.0A-E3/54 under standard surge conditions?
The SA6.0A-E3/54 has a maximum clamping voltage (VC) of 48.5 V when subjected to a 600 A peak pulse current with a 10/1000 μs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The SA6.0A-E3/54 maintains this clamping performance across its specified operating temperature range.
Is the SA6.0A-E3/54 suitable for automotive applications?
Yes-the SA6.0A-E3/54 is RoHS-compliant and manufactured to Vishay's commercial-grade specifications; its AEC-Q101-qualified counterpart is the SA6.0AHE3/54. While the E3 suffix itself is not AEC-Q101 certified, the SA6.0A-E3/54 shares identical electrical and thermal characteristics with the HE3 variant and is widely deployed in non-safety-critical automotive subsystems such as infotainment power rails and body control modules where qualification documentation is not mandated.
What does the "-E3/54" suffix indicate in SA6.0A-E3/54?
The "-E3" denotes Vishay's RoHS-compliant, commercial-grade termination meeting JESD201 Class 1A whisker test requirements; "/54" specifies the preferred packaging code for 13-inch paper tape and reel, with 4000 units per reel. This ordering format ensures consistent handling, automated placement compatibility, and traceable lot control for the SA6.0A-E3/54 in high-volume manufacturing.
How does the SA6.0A-E3/54 compare to bidirectional TVS diodes like SA6.0CA?
The SA6.0A-E3/54 is unidirectional and intended for DC power line or single-polarity signal protection, with cathode marked for correct orientation. In contrast, SA6.0CA is bidirectional and used for AC lines or differential signals where polarity reversal occurs. Both share identical VWM, VBR, and PPPM, but the SA6.0A-E3/54 provides lower leakage (<1.0 μA vs. ≤600 μA for SA6.0CA at VWM) and avoids ambiguity in grounding schemes typical of unidirectional layouts.
What is the junction temperature limit and thermal derating behavior of the SA6.0A-E3/54?
The SA6.0A-E3/54 has a maximum junction temperature (TJ) of +175 °C and follows Vishay's standard derating curve: power dissipation decreases linearly from 3.0 W at 75 °C lead temperature to zero at 175 °C. Derating above 25 °C ambient is defined in Figure 2 of the datasheet (Document 88378), ensuring safe operation in enclosed industrial enclosures or under-hood automotive locations where ambient temperatures exceed 85 °C.
