Product details
Overview
P6KE160A-E3/73 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 136 V standoff voltage (VWM), 152–168 V breakdown range (VBR at 1.0 mA), 219 V maximum clamping voltage at 2.7 A peak pulse current, 600 W peak pulse power (10/1000 µs), and DO-15 package with AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE160A-E3/73 datasheet, P6KE160A-E3/73 pinout, P6KE160A-E3/73 application, or P6KE160A-E3/73 equivalent, this device is selected for robust surge immunity in 12–48 V industrial control inputs, automotive body electronics, and telecom interface protection where fast clamping (<1 ns response), low leakage (<1.0 µA at VWM), and stable thermal performance up to 175 °C junction temperature are critical.
Technical Context
The P6KE160A-E3/73 operates as a silicon avalanche diode with glass-passivated junction, delivering precise bidirectional-capable unidirectional clamping behavior. Its 20 °C/W junction-to-lead thermal resistance enables effective heat dissipation under repetitive surge conditions, while its 0.108 %/°C breakdown voltage temperature coefficient ensures predictable VBR drift across operating temperature.
Designed for 10/1000 µs waveform compliance, it sustains 2.7 A peak pulse current with 219 V clamping-critical for protecting downstream MOSFETs and ICs against ISO 7637-2 Pulse 1/2a/5a transients. The device meets JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 Class 1A whisker resistance, confirming suitability for automated assembly in high-reliability production.
Key Specifications

Pinout & Package
DO-15 (DO-204AC) molded epoxy package with matte tin-plated leads; cathode indicated by color band on one end. Leads meet J-STD-002 and JESD 22-B102 solderability standards. Body diameter: 0.130–0.138 inch (3.3–3.5 mm); length: ≥1.0 inch (25.4 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration; conducts during positive transients relative to cathode. |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 24 V supply or CAN_H); avalanches into conduction when line voltage exceeds VBR, shunting surge to ground. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | Same VWM (136 V) and VC (219 V), but SMC package (surface-mount); 600 W rating; lower RθJA (50 °C/W vs. 75 °C/W). | Requires PCB redesign for SMD layout; better suited for space-constrained designs with reflow assembly. | Select SMBJ160A when board real estate is limited and thermal management via copper pour is feasible. |
| 1.5KE160A | Same DO-15 package and electrical specs, but 1.5 kW peak power rating; larger die size; higher IPPM (10.5 A at same VC). | Overqualified for 600 W needs; higher cost and larger footprint than necessary for most 24–48 V systems. | Select 1.5KE160A only if future-proofing for higher-energy surge standards (e.g., IEC 61000-4-5 Level 5) is required. |
Compared with SMBJ160A, P6KE160A-E3/73 offers proven through-hole manufacturability and legacy compatibility; compared with 1.5KE160A, it delivers optimal cost-performance balance for standard 600 W surge requirements without over-engineering.

FAQ
What is the standoff voltage (VWM) of the P6KE160A-E3/73?
The P6KE160A-E3/73 has a standoff voltage (VWM) of 136 V, meaning it remains non-conductive under continuous reverse bias up to this voltage. This value is derived from the 10% margin below its minimum breakdown voltage (152 V), ensuring stable operation in 120 V AC-derived or 48 V DC systems with ripple and tolerance margins. The P6KE160A-E3/73 maintains leakage current below 1.0 µA at this voltage.
How does the P6KE160A-E3/73 differ from the P6KE160CA variant?
The P6KE160A-E3/73 is unidirectional, with a cathode band indicating polarity and clamping only in reverse bias; the P6KE160CA is bidirectional, lacking polarity marking and clamping symmetrically in both directions. Their VBR ranges differ: P6KE160A-E3/73 is 152–168 V (unidirectional), while P6KE160CA is not defined in this family-P6KE160CA does not exist per Vishay's documentation, as bidirectional versions stop at P6KE440CA. The P6KE160A-E3/73 is therefore strictly unidirectional.
Is the P6KE160A-E3/73 suitable for automotive applications?
The P6KE160A-E3/73 carries the E3 suffix, indicating RoHS-compliant commercial grade-not AEC-Q101 qualified. For automotive use, the HE3 suffix variant (e.g., P6KE160AHE3/73) is required, as it undergoes additional stress testing per AEC-Q101. The P6KE160A-E3/73 may be used in non-safety-critical aftermarket or infotainment subsystems, but the P6KE160A-E3/73 itself is not certified for under-hood or safety-related ECUs.
What is the maximum clamping voltage (VC) of the P6KE160A-E3/73 under surge conditions?
The P6KE160A-E3/73 has a maximum clamping voltage (VC) of 219 V at 2.7 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value represents the upper voltage limit imposed on the protected circuit during worst-case surge events and is measured per JEDEC standards. Designers use this VC to verify that downstream components' absolute maximum ratings remain unexceeded when the P6KE160A-E3/73 activates.
Can the P6KE160A-E3/73 be used in parallel for higher surge current handling?
No-parallel connection of P6KE160A-E3/73 devices is not recommended due to mismatched avalanche characteristics causing current imbalance and premature failure of one unit. For higher surge capacity, select a single higher-rated device (e.g., 1.5KE160A) or implement staged protection (GDT + TVS). The P6KE160A-E3/73 is characterized for individual use; its 2.7 A IPPM rating assumes standalone operation with proper PCB trace inductance control.
