Product details
Overview
SA13C from Taiwan Semiconductor is a unidirectional 500W transient voltage suppressor (TVS) diode with 13V working stand-off voltage, 14.4–17.6V breakdown voltage at 1mA test current, and 22A peak pulse current capability under 10/1000μs waveform; it clamps transients to ≤23.8V and is used for ESD and inductive load protection in automotive lighting and power supply inputs.
For engineers reviewing the SA13C datasheet, SA13C pinout, SA13C application, or SA13C equivalent, key selection criteria include its DO-204AC (DO-15) package, unidirectional polarity, 1μA max reverse leakage at 13V, -55°C to +175°C operating junction temperature, and AEC-Q101 qualification option (SA13CH).
Technical Context
The SA13C operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its VBR range (14.4–17.6V), then clamping transient energy to ≤23.8V at 22A IPPM. Its low dynamic impedance enables effective suppression of fast electrical fast transients (EFT) and ISO 7637-2 pulses.
Designed for surface-mount or through-hole PCB integration, it features pure tin-plated leads compliant with J-STD-002, UL 94V-0 molding compound, and meets JESD201 Class 2 whisker resistance. Polarity is marked by cathode band per DO-204AC mechanical standard.

Pinout & Package
SA13C uses the DO-204AC (DO-15) axial package with two terminals: anode and cathode. Polarity is indicated by a cathode band on the body. Leads are pure tin-plated and solderable per J-STD-002. Mounting requires 10 × 10 mm copper pads per terminal for rated PD = 3 W at TL = 75°C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ13A | Same DO-214AC package; 13V VWM, 14.4–15.9V VBR, 23.2V [email protected]; slightly lower PPK (400W) | Not AEC-Q101 qualified; suited for commercial-grade industrial use only | Select SMAJ13A if cost sensitivity outweighs automotive qualification and 100W lower surge margin is acceptable |
| ON Semiconductor 1.5SMC13A | DO-214AB package; 13V VWM, 14.4–15.9V VBR, 21.5V [email protected]; 1.5kW PPK but larger footprint | Higher power rating but incompatible pinout and board space; requires layout change | Choose 1.5SMC13A only when system-level surge threat exceeds 500W and PCB real estate permits SMC package |
Compared with SMAJ13A and 1.5SMC13A, SA13C delivers AEC-Q101 readiness in DO-15 form factor with balanced clamping (23.8V), precise 13V standoff, and verified 500W surge capacity-making it optimal for space-constrained automotive and industrial edge nodes where qualification and reliability are non-negotiable.

FAQ
What is the maximum clamping voltage of SA13C under standard 10/1000μs surge conditions?
The SA13C has a maximum clamping voltage (VC) of 23.8 V when subjected to its rated peak pulse current of 22 A under the 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that protected downstream circuitry will not experience voltages exceeding this level during specified surge events.
Is SA13C unidirectional or bidirectional, and how is polarity identified?
SA13C is a unidirectional TVS diode. Polarity is identified by a cathode band marked on the DO-204AC (DO-15) package body. The cathode terminal must be connected toward the protected line (e.g., 12V rail), and the anode to ground to ensure proper clamping operation during reverse overvoltage events.
Does SA13C meet automotive qualification standards?
The base SA13C is not AEC-Q101 qualified; however, the SA13CH variant-identical in electrical specs and DO-204AC packaging-is fully AEC-Q101 qualified. Engineers selecting for automotive applications should specify SA13CH to ensure compliance with stress tests including temperature cycling, humidity bias HAST, and mechanical shock.
What is the reverse leakage current of SA13C at its working stand-off voltage?
At its working stand-off voltage (VWM) of 13 V, the SA13C exhibits a maximum reverse leakage current (IR) of 1 μA at TA = 25°C. This low leakage ensures minimal power loss and signal interference in always-on or battery-operated systems where quiescent current budget is critical.
Can SA13C be used in both through-hole and surface-mount assemblies?
SA13C uses the axial DO-204AC (DO-15) package with leaded terminations, making it compatible with through-hole wave soldering and hand assembly. While not designed for SMT reflow, it can be mounted on SMT boards using through-hole pads or adapter carriers-but thermal and mechanical reliability require adherence to TSC's recommended pad layout (10 × 10 mm copper per lead) and lead-forming guidelines.
