Product details
Overview
P6KE36CAH from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in automotive and industrial power rails. It features a 36V nominal standoff voltage, 52.0V maximum clamping voltage at 12.0A peak pulse current, 600W peak pulse power rating (10/1000μs), and AEC-Q101 qualification for under-hood applications.
For engineers reviewing the P6KE36CAH datasheet, P6KE36CAH pinout, P6KE36CAH application, or P6KE36CAH equivalent, key selection criteria include bidirectional clamping performance, DO-15 package compatibility with high-reliability PCB layouts, junction temperature range (−55°C to +175°C), and compliance with IEC 61000-4-4/5 EFT/surge immunity requirements.
Technical Context
The P6KE36CAH operates as a silicon avalanche diode with symmetrical breakdown characteristics in both polarities, enabling robust protection against reverse- and forward-polarity transients without external polarity management. Its low dynamic impedance and sub-5ns response time ensure rapid clamping before sensitive downstream circuitry sustains damage.
Designed for unidirectional or bidirectional use (denoted by "C" or "CA" suffix), the device meets UL 94V-0 flammability standards and supports soldering per J-STD-002. It delivers 600W surge capability at 10/1000μs waveform while maintaining ≤1μA reverse leakage above 30.8V standoff voltage at 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 36 V - defines rated working voltage threshold before avalanche conduction begins |
| Breakdown Voltage (VBR) | 32.4–39.6 V - guaranteed conduction onset range at 1 mA test current, critical for precise overvoltage triggering |
| Standoff Voltage (VWM) | 30.8 V - maximum continuous reverse voltage the device blocks without significant leakage |
| Clamping Voltage (VC) | 52.0 V at 12.0 A - peak voltage seen by protected circuit during full 600W surge event |
| Peak Pulse Power | 600 W - energy-handling capacity under standardized 10/1000μs transient waveform |
| Junction Temperature Range | −55°C to +175°C - enables operation in under-hood automotive and industrial environments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and mechanical stress tests |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band marking for unidirectional variants; P6KE36CAH is bidirectional and marked without polarity band. Leads are pure tin-plated and solderable per J-STD-002; weight ≈0.400 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction | No functional polarity - either lead serves as input/output for transient suppression in AC or floating DC systems |
| Lead 1 / Lead 2 | Current path terminals | Leads connect directly to protected line and ground; no internal biasing or control logic - purely passive clamping |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping symmetry | Identical VBR min/max (32.4–39.6 V) and VC (52.0 V) in both directions - eliminates need for polarity-aware layout |
| Fast transient response | <5.0 ns response time from 0 V to VBR - ensures clamping activation before IC-level damage thresholds are exceeded |
| Low leakage at operating voltage | ≤1 μA reverse current at 30.8 V standoff - prevents parasitic loading on 24–36 V power rails |
| High surge endurance | 600 W peak power handling with derating to 5 W steady-state at 75°C - supports repeated surge events in motor drive and lighting systems |
| Automotive-grade reliability | AEC-Q101 qualified (excluding early low-voltage variants) - validated for thermal shock, humidity, and mechanical vibration per automotive standards |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA | Same 36 V nominal, 52.0 V clamping, but SMB package (surface-mount); lower 600 W rating derates faster above 75°C | Preferred for space-constrained PCBs; not suitable for through-hole legacy designs or high-vibration mechanical mounting | Select SMBJ36CA only when board real estate is limited and reflow assembly is available. |
| 1.5KE36CA | Same DO-15 package and 36 V rating, but 1500 W peak power; larger die, higher capacitance (~150 pF vs. ~50 pF), slower response (~10 ns) | Better for high-energy lightning surges; less suitable for fast EFT or digital signal line protection due to higher capacitance | Choose 1.5KE36CA where surge energy exceeds 600 W but timing-critical signal integrity is not required. |
Compared with SMBJ36CA and 1.5KE36CA, P6KE36CAH offers optimal balance of AEC-Q101 qualification, DO-15 mechanical robustness, 5 ns response, and 600 W capability-making it ideal for automotive power rail and industrial control applications demanding proven reliability and fast clamping.

FAQ
What does the "CA" suffix indicate in P6KE36CAH?
The "CA" suffix in P6KE36CAH denotes bidirectional configuration with symmetrical avalanche characteristics in both polarities, enabling protection of AC-coupled or floating DC circuits without polarity constraints. This distinguishes it from unidirectional "A" variants like P6KE36A, which require correct anode/cathode orientation. The "H" suffix confirms AEC-Q101 qualification per the manufacturer's ordering code specification.
Is P6KE36CAH compatible with lead-free reflow soldering processes?
Yes, P6KE36CAH uses pure tin-plated leads compliant with J-STD-002 for solderability, and its DO-15 package is rated for standard lead-free reflow profiles (peak temperature up to 260°C). The epoxy molding compound meets UL 94V-0 flammability requirements and withstands multiple thermal cycles without delamination or parameter shift.
How does the clamping voltage of P6KE36CAH compare to its breakdown voltage?
P6KE36CAH has a breakdown voltage (VBR) range of 32.4–39.6 V at 1 mA, while its maximum clamping voltage (VC) is 52.0 V at 12.0 A peak pulse current. This 32–61% voltage rise reflects the device's dynamic impedance under surge conditions and defines the upper voltage limit imposed on protected circuitry during transient events.
Can P6KE36CAH be used in parallel to increase surge current handling?
No-P6KE36CAH should not be paralleled without external balancing resistors, as minor VBR mismatches between units cause uneven current sharing and potential thermal runaway. For higher surge ratings, select a single higher-power device such as 1.5KE36CA or verify matched-bin pairing per TSC application guidance. The P6KE36CAH datasheet does not recommend or characterize parallel operation.
What is the maximum operating temperature for P6KE36CAH in continuous service?
P6KE36CAH has a maximum junction temperature (TJ) of +175°C and a storage temperature range of −55°C to +175°C. In continuous service, its steady-state power dissipation is rated at 5 W at TA = 75°C with 9.5 mm lead lengths; derating curves (Fig.2) must be applied for ambient temperatures above 75°C to maintain safe junction temperature limits.
