Product details
Overview
P6KE36A from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage clamping in DC power rails and signal lines. It features a nominal breakdown voltage of 36 V, maximum clamping voltage of 49.9 V at 12.6 A peak surge current, and stand-off voltage of 30.8 V - enabling reliable protection of 24–32 V systems against ESD, lightning-induced surges, and inductive switching transients in automotive body electronics and industrial PLC I/O modules.
For engineers reviewing the P6KE36A datasheet, P6KE36A pinout, P6KE36A application, or P6KE36A equivalent, key selection criteria include its DO-204AC (DO-15) axial package, unidirectional polarity with cathode band marking, 175°C junction rating, low dynamic impedance, and AEC-Q101 qualification for automotive-grade reliability - all critical for robust front-end surge immunity design.
Technical Context
The P6KE36A operates as a silicon avalanche diode optimized for fast clamping response (<1.0 ps rise time from 0 V to VBR) and low leakage (<1 μA at 30.8 V). Its single-die construction in a DO-204AC package delivers precise voltage threshold control with ±5% VBR tolerance (34.2–37.8 V), supported by a temperature coefficient of 0.099%/°C.
It complies with ANSI/IEEE C62.35 for transient suppression and is rated for non-repetitive 10/1000 μs waveform surges up to 600 W. The device sustains 100 A forward surge current (8.3 ms half-sine) and maintains stable clamping performance across –55°C to +175°C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 34.2 V / 37.8 V - defines precise clamping onset window; ensures consistent turn-on before downstream IC damage thresholds in 24 V systems. |
| VWM | 30.8 V - maximum continuous reverse working voltage; allows safe operation above 24 V nominal rail with margin for ripple and tolerance. |
| VC @ IPP | 49.9 V @ 12.6 A - peak clamped voltage during 10/1000 μs surge; limits stress on protected 3.3 V/5 V logic interfaces when used with series impedance. |
| PPK | 600 W - peak pulse power rating; supports high-energy transients like ISO 7637-2 Pulse 1/2a/5a in automotive environments. |
| IR @ VWM | <1 μA - ultra-low reverse leakage; prevents measurable power loss or bias shift in high-impedance sensor or reference circuits. |
| TJMAX | +175°C - extended junction temperature rating; enables placement near hot components (e.g., power MOSFETs, DC-DC inductors) without derating. |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package; compatible with through-hole assembly and manual rework; 0.400 g weight aids mechanical stability. |
Pinout & Package
DO-204AC (DO-15) axial package with cathode band marking; leads are pure tin plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., GND or return path); conducts during forward surge events (e.g., reverse battery connection). |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 24 V rail); avalanches into low-impedance state when voltage exceeds VBR, shunting surge current to ground. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood applications including engine control units and lighting modules - meets stress test requirements for temperature cycling, HTRB, and ESD. |
| 600 W surge capability | Handles ISO 7637-2 Pulse 5a (500 V, 10/1000 μs) without degradation when properly mounted on 5×5 mm copper pads - eliminates need for parallel TVS stacking. |
| Clamping voltage ≤49.9 V | Ensures protected 3.3 V microcontrollers and CAN transceivers remain below absolute maximum ratings during worst-case surge events on 24 V supply lines. |
| Dynamic impedance <1 Ω | Minimizes voltage overshoot during fast transients (e.g., EFT bursts), improving immunity margin for sensitive analog front-ends and ADC references. |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and UL 94V-0 molding compound - supports green manufacturing and end-of-life compliance for industrial and automotive OEMs. |

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 SMAJ36A | Same DO-214AC (SMA) package; 36 V VBR (34.2–37.8 V), but lower 400 W PPK; higher VC = 58.1 V @ 6.9 A. | Requires higher series impedance to achieve same clamping level; less suitable for high-current 24 V systems with tight voltage margins. | Select when space-constrained SMT layout is mandatory and surge energy is limited to ≤400 W. |
| ON Semiconductor 1.5KE36A | Same DO-204AC (DO-15) package; identical VBR/VC specs and 600 W rating, but not AEC-Q101 qualified; higher typical IR = 5 μA @ VWM. | Lacks automotive qualification; may require additional validation for under-hood deployment; higher leakage affects ultra-low-power sensor nodes. | Select for cost-sensitive industrial applications where AEC-Q101 is not mandated and leakage sensitivity is low. |
Compared with SMAJ36A and 1.5KE36A, the P6KE36A uniquely combines AEC-Q101 qualification, DO-204AC through-hole compatibility, and 49.9 V clamping at full 600 W - making it optimal for automotive and high-reliability industrial designs requiring proven field performance and easy manual inspection.

FAQ
What is the maximum clamping voltage of the P6KE36A under surge conditions?
The P6KE36A has a maximum clamping voltage (VC) of 49.9 V when subjected to its rated peak pulse current of 12.6 A using the 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream components connected to the protected line will not experience voltage stress exceeding this threshold during standardized surge events - a critical parameter for ensuring robustness in 24 V automotive and industrial systems where the P6KE36A is deployed.
Is the P6KE36A suitable for automotive applications?
Yes, the P6KE36A is AEC-Q101 qualified (as indicated by the "H" suffix option in ordering codes), meaning it has passed rigorous stress tests including temperature cycling, high-temperature reverse bias, and ESD immunity required for automotive under-hood and chassis applications. While the base P6KE36A part number does not carry the "H" suffix, Taiwan Semiconductor explicitly lists AEC-Q101 qualification as available for the P6KE series - and the P6KE36A's electrical and thermal specifications (e.g., TJMAX = 175°C, VBR tolerance, low IR) fully align with automotive-grade performance requirements.
What is the difference between P6KE36 and P6KE36A?
The "A" suffix in P6KE36A denotes tighter VBR tolerance: P6KE36 has a breakdown voltage range of 32.4–39.6 V (±10%), while P6KE36A narrows this to 34.2–37.8 V (±5%). This improved tolerance ensures more predictable clamping behavior in precision 24 V systems, reduces design margin uncertainty, and simplifies compliance testing for standards like ISO 7637-2. All other parameters - including VWM, VC, PPK, and package - are identical between the two variants, making P6KE36A the preferred choice for high-reliability applications.
What package type does the P6KE36A use, and is it RoHS compliant?
The P6KE36A uses the DO-204AC (DO-15) axial leaded package with pure tin-plated leads, compliant with J-STD-002 for solderability and JESD 201 Class 2 for whisker resistance. It is fully RoHS compliant and halogen-free per IEC 61249-2-21, with a UL 94V-0 rated molding compound. This makes the P6KE36A suitable for both automated through-hole assembly and manual rework in environmentally regulated industries including automotive, medical, and industrial automation - where material compliance is audited at the BOM level.
How does the P6KE36A compare to bidirectional TVS diodes in surge protection?
The P6KE36A is unidirectional and optimized for DC power rail protection where polarity is fixed - such as 24 V supplies in automotive BCMs or industrial PLCs. Unlike bidirectional types (e.g., P6KE36CA), it provides lower leakage (<1 μA vs. ~5 μA) and faster response (<1.0 ps vs. 5.0 ns) in the reverse direction, while blocking forward current until ~1.2 V. This makes the P6KE36A superior for applications requiring minimal standby power loss and precise clamping onset, whereas bidirectional variants are reserved for AC-coupled or polarity-agnostic signal lines like USB or RS-485.
