Product details
Overview
P6KE120 from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 120V nominal breakdown voltage (VBR min/max: 108–132V), 97.2V standoff voltage (VWM), clamps to ≤173V at 3.6A peak surge current, and uses DO-204AC (DO-15) axial package for industrial power supply input protection.
For engineers reviewing the P6KE120 datasheet, P6KE120 pinout, P6KE120 application, or P6KE120 equivalent, key selection criteria include its 173V clamping voltage at 3.6A IPP, 108–132V VBR tolerance, low 1μA leakage at VWM, AEC-Q101 qualification option (P6KE120H), and compatibility with 10/1000μs surge waveforms in automotive and industrial ESD/EFT protection circuits.
Technical Context
The P6KE120 operates as a silicon avalanche diode that enters controlled breakdown when reverse voltage exceeds its VBR range (108–132V), diverting transient energy to ground while limiting downstream voltage to ≤173V. Its fast response time (<1.0ps from 0V to VBR) ensures protection against nanosecond-scale transients like ESD and electrical fast transients.
Rated for 600W non-repetitive peak pulse power (10/1000μs), it sustains junction temperatures up to +175°C and exhibits a temperature coefficient of VBR of 0.107%/°C - critical for stable clamping across wide ambient ranges in automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 97.2 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC rail margin below clamping threshold |
| VBR (min/max) | 108 V / 132 V - Breakdown occurs within this range at 1 mA test current; determines minimum overvoltage trigger point |
| VC @ IPP | 173 V @ 3.6 A - Clamped voltage during 10/1000μs surge; sets worst-case stress on protected IC or regulator |
| IPP (max) | 3.6 A - Peak surge current capability at rated clamping voltage; defines maximum transient energy absorption |
| PPK | 600 W - Non-repetitive peak pulse power rating; validates suitability for IEC 61000-4-5 Level 3/4 surge testing |
| IR @ VWM | <1 μA - Reverse leakage at standoff voltage; ensures negligible standby power loss in always-on systems |
| TJ(max) | +175 °C - Maximum junction temperature; supports operation in high-ambient environments like engine control units |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band marking. Complies with UL 94V-0 flammability rating and JESD201 Class 2 whisker resistance. Leads are pure tin-plated and solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-impedance return path; completes clamping loop during transient events |
| Cathode | Protected line connection | Connected to line being protected (e.g., 120V DC input); reverse-biased during normal operation, avalanches during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| 600W surge rating (10/1000μs) | Validates compliance with IEC 61000-4-5 surge immunity requirements for industrial and automotive power inputs |
| <1.0ps response time (unidirectional) | Enables suppression of sub-nanosecond ESD events before sensitive downstream circuitry experiences overstress |
| AEC-Q101 qualified variant available (P6KE120H) | Meets automotive-grade reliability standards including temperature cycling, HTRB, and mechanical shock for under-hood use |
| Low dynamic impedance | Ensures minimal voltage overshoot during high-di/dt transients by maintaining tight VC–IPP relationship |
| RoHS & halogen-free (IEC 61249-2-21) | Supports environmentally compliant manufacturing and end-of-life recycling in global electronics supply chains |

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 SMAJ120A | Same DO-214AC (SMA) package; 120V VBR (114–126V), 173V VC @ 3.6A, but lower 400W PPK | Lower surge rating limits use to lighter-duty IEC 61000-4-5 Level 2 applications; not AEC-Q101 qualified | Select when space-constrained PCB layout requires surface-mount and full 600W rating is not required. |
| ON Semiconductor 1.5KE120A | Same DO-204AC (DO-15) package; identical 120V VBR, 97.2V VWM, 173V VC, but rated 1500W PPK (10/1000μs) | Higher surge rating enables single-device protection for harsher environments (e.g., railway traction power), but larger thermal mass affects response consistency | Select when legacy 1.5KE footprint compatibility is mandatory and higher surge margin is needed beyond 600W. |
Compared with P6KE120, SMAJ120A offers SMT convenience at reduced surge capacity, while 1.5KE120A delivers higher power headroom in the same through-hole form factor - making P6KE120 the optimal balance of proven reliability, AEC-Q101 readiness, and standardized 600W protection for cost-sensitive industrial designs.

FAQ
What is the maximum clamping voltage of P6KE120 under surge conditions?
The P6KE120 clamps to a maximum of 173 V when subjected to its rated peak pulse current of 3.6 A using the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and represents the worst-case voltage seen by downstream components during transient events - critical for ensuring voltage margins of protected ICs and regulators remain intact.
Is P6KE120 suitable for automotive applications?
Yes - the P6KE120H variant is AEC-Q101 qualified and tested for automotive-grade reliability, including temperature cycling, high-temperature reverse bias, and mechanical shock. While the base P6KE120 is not qualified, its electrical specs (173 V clamping, 175 °C TJ max, low leakage) align with common BCM and infotainment power rail protection needs when validated per OEM requirements.
What is the standoff voltage (VWM) of P6KE120 and why does it matter?
The P6KE120 has a standoff voltage VWM of 97.2 V, meaning it remains in high-impedance state up to this DC or RMS voltage level. This parameter ensures no significant leakage current flows during normal operation, avoiding unnecessary power loss or false triggering - especially vital in always-on 120 VDC systems where efficiency and stability are prioritized.
How does P6KE120 differ from P6KE120A?
The P6KE120A has a tighter VBR range (114–126 V vs. 108–132 V for P6KE120) and slightly higher VWM (102 V), resulting in improved voltage margin control and lower risk of premature conduction. Both share identical clamping voltage (173 V), surge rating (600 W), and package - making P6KE120A preferable where precision clamping threshold is critical, such as in regulated 120 VDC distribution networks.
Can P6KE120 be used in bidirectional configurations?
No - P6KE120 is a unidirectional TVS diode intended for DC line-to-ground protection only. For bidirectional AC or dual-polarity signal line protection, the P6KE120CA variant (with "CA" suffix) must be used, which provides symmetrical breakdown in both directions and is explicitly designated for bipolar applications per Taiwan Semiconductor's ordering guide.
