Product details
Overview
P6SMB160AHE3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 136 V stand-off voltage (VWM), 152–168 V breakdown voltage (VBR) at 1 mA, 219 V maximum clamping voltage (VC) at 2.7 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs waveform). It is AEC-Q101 qualified and RoHS-compliant, targeting automotive and industrial electronics protection.
For engineers reviewing the P6SMB160AHE3/52 datasheet, P6SMB160AHE3/52 pinout, P6SMB160AHE3/52 application, or P6SMB160AHE3/52 equivalent, key selection criteria include clamping performance under 10/1000 μs surge, thermal resistance (RθJA = 100 °C/W), unidirectional polarity with cathode band marking, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This TVS diode operates as a voltage-clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (VBR = 152–168 V), limiting transient energy to protect downstream ICs and MOSFETs. Its low incremental surge resistance ensures stable clamping during fast transients, and its glass-passivated junction enables robust surge handling up to 100 A IFSM (8.3 ms half-sine).
The device is rated for continuous operation from –65 °C to +150 °C junction temperature, with thermal resistance of 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads. It meets MSL Level 1 per J-STD-020 and supports automated SMT placement due to its low-profile SMB package and matte tin-plated leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 136 V - Maximum continuous reverse operating voltage before significant leakage; defines safe working margin below clamping onset. |
| VBR (Breakdown) | 152–168 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping) | 219 V at IPPM = 2.7 A (10/1000 μs) - Peak voltage seen by protected circuit during worst-case transient; critical for IC voltage tolerance margin. |
| PPPM | 600 W - Peak pulse power handling capability under standardized 10/1000 μs waveform; determines survivability against common lightning/inductive spikes. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on recommended pad layout; informs derating requirements above 25 °C ambient. |
| TJ max. | +150 °C - Maximum allowable junction temperature; enables operation in under-hood automotive environments. |
| AEC-Q101 | Qualified - Validated for automotive applications including temperature cycling, humidity bias, and mechanical shock per AEC stress test standards. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with UL 94 V-0 flammability rating and matte tin-plated leads solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Reverse-biased anode connection point | Marked terminal accepts positive transient voltage relative to anode; defines unidirectional conduction path during clamping. |
| Anode | Reference/ground connection | Connected to system ground or lower-potential rail; completes clamping path to shunt surge current away from protected load. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-E3/52 | Same VWM (136 V), VC = 221 V at 2.6 A; SMA package (DO-214AC), higher RθJA (140 °C/W); no AEC-Q101 qualification. | Limited to commercial-grade industrial or consumer use; unsuitable for automotive due to lack of AEC-Q101 validation. | Select when cost sensitivity outweighs automotive qualification needs and thermal budget allows higher RθJA. |
| 1.5SMC160AHE3_A/H | Same VWM/VBR/VC specs; SMC (DO-214AB) package, larger footprint (7.11 mm × 6.22 mm vs. SMB's 4.57 mm × 3.94 mm); RθJA = 70 °C/W. | Better thermal performance but requires PCB real estate increase; used where sustained surge repetition demands lower junction temperature rise. | Prefer when system-level thermal management is constrained and board space permits larger SMC footprint. |
Compared with P6SMB160AHE3/52, SMAJ160A-E3/52 offers identical electrical clamping but lacks automotive qualification and has inferior thermal performance, while 1.5SMC160AHE3_A/H delivers superior thermal dissipation at the cost of larger PCB area-making P6SMB160AHE3/52 the optimal balance of AEC-Q101 compliance, compact SMB size, and verified 600 W surge handling.

FAQ
What is the clamping voltage of P6SMB160AHE3/52 at its rated peak pulse current?
The P6SMB160AHE3/52 has a maximum clamping voltage (VC) of 219 V when subjected to its specified peak pulse current (IPPM) of 2.7 A under the 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet (Document Number: 88370) and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB160AHE3/52 maintains this clamping performance across its qualified operating temperature range.
Is P6SMB160AHE3/52 suitable for automotive applications?
Yes, P6SMB160AHE3/52 is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in Revision 09-Jan-2024 of datasheet 88370. It undergoes stress testing for temperature cycling, humidity bias, and mechanical shock required for automotive under-hood and body electronics. The P6SMB160AHE3/52 is explicitly designated for automotive use in its mechanical data section and supports applications like ECU power rail protection and sensor interface hardening.
What is the package type and mounting configuration of P6SMB160AHE3/52?
P6SMB160AHE3/52 uses the SMB (DO-214AA) surface-mount package, measuring 4.57 mm × 3.94 mm × 2.29 mm with a low-profile profile optimized for automated placement. It features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and is supplied in 7" plastic tape-and-reel format (code /52). The cathode is marked by a visible band on the banded end, indicating polarity for unidirectional operation. The P6SMB160AHE3/52 requires 0.2" × 0.2" copper pads per terminal for thermal and mechanical reliability.
How does the thermal resistance of P6SMB160AHE3/52 affect its power derating?
P6SMB160AHE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads. This value directly governs its power derating curve: above 25 °C ambient, its 5.0 W steady-state power dissipation must be linearly reduced by 50 mW/°C (per Figure 2 in datasheet 88370). For example, at 75 °C ambient, P6SMB160AHE3/52 is limited to 2.5 W continuous dissipation. The P6SMB160AHE3/52's thermal behavior is validated per JEDEC standards and impacts both DC bias stability and repetitive surge endurance.
What is the difference between P6SMB160AHE3/52 and P6SMB160CAHE3/52?
P6SMB160AHE3/52 is unidirectional, with polarity indicated by a cathode band and intended for DC rail protection where current flows in one direction. P6SMB160CAHE3/52 is bidirectional, lacking polarity marking and suitable for AC-coupled or symmetrical signal line protection (e.g., RS-485, USB D+/D−). Their breakdown voltages differ: P6SMB160AHE3/52 has VBR = 152–168 V, while P6SMB160CAHE3/52 has VBR = 152–168 V in both directions. The P6SMB160AHE3/52 cannot substitute for the bidirectional variant in AC applications without risk of forward conduction failure.
