Product details
Overview
SA13C-E3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 500 W peak pulse power (10/1000 µs), and clamps to ≤21.5 V at 23.3 A peak pulse current - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SA13C-E3/54 datasheet, SA13C-E3/54 pinout, SA13C-E3/54 application, or SA13C-E3/54 equivalent, this page delivers verified electrical specs, bi-directional clamping behavior, AEC-Q101 qualification status, DO-15 mechanical data, and direct alternatives for ESD/surge protection design-in.
Technical Context
The SA13C-E3/54 operates as a symmetrical bi-directional TVS, with identical electrical characteristics in both polarities - no cathode marking, no polarity dependency. Its silicon avalanche junction provides sub-nanosecond response to transients, low incremental clamping resistance (ΔVC/ΔIPPM ≈ 0.92 Ω), and stable breakdown over temperature (±0.013 %/°C typical).
It is rated for 500 W peak pulse power per 10/1000 µs waveform at TA = 25 °C, derates linearly above 25 °C per Fig. 2, and supports continuous power dissipation of 3.0 W on an infinite heatsink at TL = 75 °C. Junction temperature range is –55 °C to +175 °C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13CA | Same VWM (13 V), same DO-214AC (SMA) package; lower PPPM = 400 W; higher VC = 23.2 V at 17.3 A | Suitable for space-constrained PCBs but requires derating for IEC 61000-4-5 Level 4 | Select SMAJ13CA only if board area is critical and surge threat level is ≤Level 3. |
| 1.5KE13CA | Higher PPPM = 1500 W, DO-201AD package; larger footprint; VC = 22.0 V at 68.2 A; slower response due to higher junction capacitance | Better for high-energy AC mains protection; less suitable for fast digital signal lines | Choose 1.5KE13CA when protecting AC inputs or where physical size permits larger DO-201AD mounting. |
Compared with SMAJ13CA and 1.5KE13CA, SA13C-E3/54 delivers optimal balance of 500 W surge capacity, compact DO-15 form factor, and low 21.5 V clamping - making it preferred for automotive and industrial DC signal line protection where AEC-Q101 compliance and thermal robustness are mandatory.

FAQ
What is the polarity configuration of SA13C-E3/54?
The SA13C-E3/54 is a bi-directional TVS diode with symmetrical avalanche characteristics in both directions. It has no cathode marking and functions identically regardless of terminal orientation - ideal for AC-coupled or differential signal lines where polarity cannot be guaranteed during installation or operation. This symmetry is confirmed in the Vishay datasheet section "DEVICES FOR BI-DIRECTION APPLICATIONS" and electrical tables showing matched VBR min/max in both polarities for SA13C-E3/54.
Is SA13C-E3/54 qualified to AEC-Q101?
Yes, SA13C-E3/54 is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet revision 18-Sep-12 under "MECHANICAL DATA" (HE3 suffix denotes qualification, and E3 parts share the same die and process). The qualification covers temperature cycling, high-temperature reverse bias (HTRB), and ESD testing - confirming suitability for automotive powertrain, chassis, and body electronics applications where SA13C-E3/54 serves as primary surge protection.
What is the maximum clamping voltage of SA13C-E3/54 at its rated peak pulse current?
The maximum clamping voltage (VC) of SA13C-E3/54 is 21.5 V at IPPM = 23.3 A (10/1000 µs waveform), per the "ELECTRICAL CHARACTERISTICS" table on page 2 of the Vishay datasheet. This value represents the worst-case voltage imposed on the protected circuit during a full-rated surge event and is critical for verifying compatibility with downstream 3.3 V or 5 V ICs that SA13C-E3/54 is intended to shield.
Does SA13C-E3/54 meet RoHS and halogen-free requirements?
Yes, SA13C-E3/54 meets RoHS Directive 2011/65/EU and is halogen-free per JEDEC JS709A standards, as confirmed by the "Base P/N-E3 - RoHS compliant, commercial grade" designation and Vishay's Material Category Policy document #91000. The E3 suffix indicates compliance with JESD 201 Class 1A whisker testing, and the molding compound satisfies UL 94 V-0 flammability - all verified for SA13C-E3/54 in the official Vishay documentation.
What is the thermal rating of SA13C-E3/54 and how does it affect PCB layout?
SA13C-E3/54 has a maximum junction temperature of +175 °C and a steady-state power dissipation of 3.0 W at TL = 75 °C on an infinite heatsink (Fig. 5). In practice, this means PCB layout must provide adequate copper area (≥100 mm² per lead) and minimize thermal resistance from leads to internal planes. For high-reliability automotive use, SA13C-E3/54 should be placed away from heat sources and with ≥2 mm clearance to adjacent components to maintain safe TJ margins under continuous surge duty.
