Product details
Overview
P6KE180AH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for robust overvoltage protection in automotive and industrial power rails. It features a 180V nominal breakdown voltage (VBR min/max: 162–198V), 146V stand-off voltage (VWM), clamps at ≤246V under 2.5A peak surge current (IPP), and delivers sub-nanosecond response (<1.0ps) to ESD and lightning-induced transients - deployed in DC power input stages of vehicle ECUs and industrial PLCs.
For engineers reviewing the P6KE180AH datasheet, P6KE180AH pinout, P6KE180AH application, or P6KE180AH equivalent, this page provides verified package mapping (DO-204AC/DO-15), AEC-Q101 qualification status, clamping performance at 10/1000μs waveform, junction temperature limit (175°C), and direct alternative part comparisons with documented VBR and VC differences.
Technical Context
The P6KE180AH operates as a unidirectional avalanche diode, leveraging silicon PN-junction breakdown to clamp transient voltages above its VWM (146V) while maintaining <1μA leakage at rated stand-off. Its low dynamic impedance ensures stable clamping during 10/1000μs surges up to 600W, with thermal derating defined per Fig.2 for ambient temperatures beyond 25°C.
Designed for AEC-Q101 compliance (per ordering code suffix "H"), it supports automotive-grade reliability including JESD201 Class 2 whisker resistance, UL 94V-0 mold compound, and pure tin-plated leads solderable per J-STD-002. Polarity is marked by cathode band; no bidirectional operation is supported.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 146 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe DC rail margin for 12V/24V/48V systems. |
| VBR (min/max) | 162 V / 198 V - Measured at 1 mA IT; guarantees clamping activation within tight tolerance band for predictable overvoltage thresholding. |
| VC @ IPP | 246 V @ 2.5 A - Peak clamped voltage during 10/1000μs surge; determines maximum stress imposed on downstream ICs during transient events. |
| PPK | 600 W - Non-repetitive peak pulse power handling at 10/1000μs; enables protection against IEC 61000-4-5 Level 4 surges (4kV line-to-ground). |
| TJ max | 175 °C - Maximum junction temperature; allows operation in under-hood automotive environments and high-ambient industrial enclosures. |
| IR @ VWM | <1 μA - Reverse leakage at 146 V; minimizes standby power loss and avoids false triggering in high-impedance sensing circuits. |
| Response time | <1.0 ps - Time from 0 V to VBR onset; ensures suppression of fast-rising ESD pulses (IEC 61000-4-2) before sensitive circuitry is damaged. |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case with cathode band marking. Dimensions conform to JEDEC DO-15 standard; weight ≈0.400 g. Leads are pure tin-plated and solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to system ground or lowest potential node; completes clamping path during positive transients on cathode side. |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., battery feed); conducts avalanche current when voltage exceeds VBR, shunting surge to ground. |

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 SMAJ180A | VBR min/max = 162–189V; VC = 259V @ 2.4A; same DO-214AC package but surface-mount vs. P6KE180AH's through-hole DO-15. | Requires PCB redesign for SMT placement; better suited for space-constrained modules where reflow compatibility is prioritized. | Select SMAJ180A only if automated assembly and footprint density outweigh mechanical robustness and hand-soldering serviceability. |
| ON Semiconductor 1.5KE180A | VBR min/max = 162–198V (identical); VC = 258V @ 2.4A; same 600W rating but legacy DO-201AD package (larger than DO-15, higher thermal mass). | Compatible with high-vibration environments due to heavier leadframe; slightly slower thermal recovery after repeated surges. | Choose 1.5KE180A when mechanical shock resistance and legacy design continuity are critical, accepting larger board area. |
Compared with SMAJ180A and 1.5KE180A, P6KE180AH offers identical electrical clamping performance in a smaller, AEC-Q101-qualified through-hole package optimized for automotive serviceability and thermal cycling endurance in under-hood locations.

FAQ
What is the AEC-Q101 qualification status of P6KE180AH?
P6KE180AH is explicitly AEC-Q101 qualified per its "H" suffix in the ordering code, validated for automotive applications including temperature cycling, humidity testing, and mechanical shock. This qualification covers the full P6KE180AH device - not just the P6KE family generically - and is documented in Taiwan Semiconductor's P2203 specification revision.
Does P6KE180AH support bidirectional transient suppression?
No, P6KE180AH is strictly unidirectional. Its cathode-band marking and electrical specifications (e.g., VBR test current applied only in reverse direction) confirm single-polarity operation. For bidirectional protection, Taiwan Semiconductor specifies CA-suffix variants (e.g., P6KE180CA), which are separate orderable parts with different internal construction.
What is the maximum peak surge current (IPP) rating for P6KE180AH at 10/1000μs?
The maximum peak surge current for P6KE180AH is 2.5 A under the 10/1000μs waveform, derived from its 600W peak pulse power rating and 246V clamping voltage (IPP = PPK / VC = 600W / 246V ≈ 2.44 A, rounded to 2.5 A in datasheet tables). This value is confirmed in the Electrical Specifications table on page 3 of the P2203 document.
How does the thermal derating of P6KE180AH work above 25°C ambient?
P6KE180AH's peak pulse power (PPK) is linearly derated above 25°C ambient per Figure 2 in the datasheet: at 75°C, PPK drops to ~450W (75% of 600W); at 125°C, it falls to ~250W (42%). This derating applies directly to surge energy handling capability and must be factored into worst-case thermal design for under-hood or enclosed industrial deployments.
Is P6KE180AH compatible with lead-free reflow soldering processes?
Yes, P6KE180AH uses pure tin-plated leads compliant with J-STD-002 for solderability, and its DO-204AC (DO-15) package is rated for peak reflow temperatures up to 260°C per JEDEC J-STD-020. The epoxy molding compound meets UL 94V-0 and is halogen-free per IEC 61249-2-21, supporting RoHS-compliant manufacturing.
