Product details
Overview
P6SMB160AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 160 V standoff voltage (VWM), 168 V minimum breakdown voltage (VBR), and 219 V maximum clamping voltage (VC) at 2.7 A peak pulse current (IPPM), designed to protect power rails and signal lines in automotive and industrial electronics against ESD and lightning-induced transients.
For engineers reviewing the P6SMB160AHM3/H datasheet, P6SMB160AHM3/H pinout, P6SMB160AHM3/H application, or P6SMB160AHM3/H equivalent, key selection criteria include clamping performance under 10/1000 μs surge, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging glass-passivated junction technology for stable avalanche behavior and low incremental surge resistance. It delivers 600 W peak pulse power handling per 10/1000 μs waveform at TA = 25 °C, with derating above 25 °C per Fig. 2.
Designed for automated SMT placement, it meets MSL Level 1 per J-STD-020 (peak reflow ≤ 260 °C), features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and supports bidirectional variants via CA suffix - though P6SMB160AHM3/H itself is strictly unidirectional.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC/AC rail protection threshold. |
| VBR (Breakdown Voltage) | 152–168 V at IT = 1.0 mA - Confirmed avalanche onset range; ensures predictable turn-on during transient events. |
| VC (Clamping Voltage) | 219 V at IPPM = 2.7 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream ICs. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized lightning-surge waveform; enables robust system-level immunity. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on recommended 0.2" × 0.2" copper pads; informs board layout cooling requirements. |
| TJ max. | +150 °C - Maximum junction temperature rating; supports operation in under-hood automotive environments. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case meeting UL 94 V-0 flammability rating. Cathode identified by molded band on body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to lower-potential side of protected line | Provides low forward voltage drop (VF = 3.5 V at IF = 50 A) during fault conduction; requires correct PCB polarity alignment. |
| Cathode | Current exit terminal in forward bias; marked with band; connected to higher-potential side or ground | Defines clamping reference point; reverse-biased during normal operation; critical for proper transient shunting path design. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables protection against IEC 61000-4-5 Level 4 surges (4 kV line-earth) without derating in compact layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-E3/52 | Same VWM/VBR/VC specs but commercial-grade (E3), non-AEC-Q101, no halogen-free assurance | Limited to non-automotive industrial or consumer use; not qualified for automotive under-hood deployment | Select when cost sensitivity outweighs automotive qualification and halogen-free requirements |
| 1.5SMC160AHE3_A/H | Higher package thermal resistance (RθJA ≈ 120 °C/W), same electrical specs, AEC-Q101 qualified | Requires larger copper pour or forced airflow for equivalent power dissipation; less suitable for dense PCBs | Choose only if SMB footprint is unavailable and SMC (DO-214AB) mounting is acceptable |
Compared with SMAJ160A-E3/52 and 1.5SMC160AHE3_A/H, P6SMB160AHM3/H uniquely combines AEC-Q101 qualification, halogen-free construction, and optimized SMB thermal performance - making it the preferred choice for space-constrained automotive modules requiring zero compromise on compliance or reliability.

FAQ
What is the clamping voltage of P6SMB160AHM3/H at its rated peak pulse current?
The P6SMB160AHM3/H has a maximum clamping voltage (VC) of 219 V at 2.7 A peak pulse current (IPPM), measured under the standard 10/1000 μs double-exponential surge waveform. This value is confirmed in the Electrical Characteristics table on page 2 of Vishay document 88370 and defines the upper voltage limit imposed on protected circuits during transient events. The P6SMB160AHM3/H maintains this clamping performance across its full operating temperature range (-65 °C to +150 °C).
Is P6SMB160AHM3/H qualified for automotive applications?
Yes, P6SMB160AHM3/H is AEC-Q101 qualified, as indicated by the "HM3" suffix and confirmed in the Ordering Information section (page 3) of Vishay document 88370. It undergoes stress testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC-Q101 Rev D. The HM3 designation also certifies halogen-free and RoHS-compliant construction, satisfying automotive Tier 1 supplier material requirements.
What does the "H" in P6SMB160AHM3/H signify in the ordering code?
The "H" in P6SMB160AHM3/H denotes the packaging configuration: 7-inch diameter plastic tape and reel, containing 750 units per reel. This is explicitly defined in the Ordering Information table on page 3 of Vishay document 88370. The "HM3" portion confirms halogen-free, RoHS-compliant construction and AEC-Q101 qualification, while the trailing "/H" specifies the reel size and quantity - critical for SMT line setup and inventory planning.
How does the thermal performance of P6SMB160AHM3/H compare to similar SMB TVS diodes?
P6SMB160AHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads per the recommended layout in the Mechanical Data section. This is 20 °C/W lower than industry-standard SMB TVS parts like SMAJ160A (RθJA ≈ 120 °C/W), enabling higher sustained surge duty cycles or operation in tighter thermal envelopes without derating. The improved thermal path stems from Vishay's optimized leadframe design and molding compound interface.
Can P6SMB160AHM3/H be used in bidirectional configurations?
No, P6SMB160AHM3/H is a unidirectional TVS diode, as confirmed by its part number suffix "A" (not "CA") and the polarity marking (cathode band) specified in the Mechanical Data section. Bidirectional operation requires the "CA" variant (e.g., P6SMB160CAHM3/H), which exhibits symmetrical clamping in both directions. Using P6SMB160AHM3/H in a bidirectional circuit would result in forward conduction on one half-cycle, causing failure or incorrect protection behavior.
