Product details
Overview
P6SMB27AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 23.1 V stand-off voltage (VWM), 25.7–28.4 V breakdown voltage (VBR) at 1 mA, 37.5 V maximum clamping voltage (VC) at 16.0 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the P6SMB27AHE3_A/H datasheet, P6SMB27AHE3_A/H pinout, P6SMB27AHE3_A/H application, or P6SMB27AHE3_A/H equivalent, this device is selected for robust ESD and surge protection where AEC-Q101 qualification, low incremental surge resistance, and fast response time (<1 ns) are required in space-constrained PCB layouts.
Technical Context
The P6SMB27AHE3_A/H operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<1.0 μA at VWM), while the SMB package supports automated placement and meets MSL level 1 reflow (260 °C peak).
It delivers 600 W transient power handling per 10/1000 μs waveform at 0.01% duty cycle, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead). The cathode band identifies polarity, and it is rated for operation from –65 °C to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 23.1 V - Maximum continuous reverse voltage before significant leakage; sets operating margin below clamping threshold |
| VBR (Breakdown) | 25.7–28.4 V at 1 mA - Confirmed avalanche onset range; defines minimum overvoltage triggering point |
| VC (Clamping) | 37.5 V at 16.0 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines safe stress limit for downstream ICs |
| PPPM | 600 W - Sustains single high-energy transients without failure; validated per IEC 61000-4-5 Level 4 |
| IPPM | 16.0 A - Peak surge current capability under standard 10/1000 μs waveform; defines minimum trace/solder joint robustness needed |

IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS on sensor signal line, referenced to local ground near connector. Use Value: Preserves <1% full-scale accuracy by limiting clamping voltage to ≤37.5 V while maintaining <1 pF junction capacitance at 0 V bias. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A | Lower PPPM (400 W), higher VC (38.9 V at 10.3 A), same SMB package, non-AEC-Q101 | Limited to commercial-grade industrial or consumer applications; not qualified for automotive under-hood use | Select when cost sensitivity outweighs AEC-Q101 requirement and surge energy is ≤400 W |
| 1.5SMC27A | Higher package thermal resistance (RθJA = 125 °C/W), same VWM/VBR, no AEC-Q101 option, SMC (DO-214AB) package (larger footprint) | Requires more PCB area; less suitable for dense automotive modules; lower power derating above 25 °C | Choose only if existing SMC footprint reuse is mandatory and AEC-Q101 is not required |
Compared with SMAJ24A and 1.5SMC27A, the P6SMB27AHE3_A/H provides superior automotive qualification, tighter VBR tolerance, lower clamping voltage, and better thermal performance in the compact SMB footprint - making it optimal for new AEC-Q101–compliant designs with strict space and reliability constraints.

FAQ
What does the "HE3_A/H" suffix indicate in P6SMB27AHE3_A/H?
The "HE3" suffix denotes RoHS-compliant and AEC-Q101 qualified construction; "A" specifies unidirectional polarity; "H" indicates packaging in 7″ diameter plastic tape and reel (750 units per reel). This full ordering code confirms automotive-grade qualification, polarity, and standard logistics format for P6SMB27AHE3_A/H.
Is P6SMB27AHE3_A/H suitable for bidirectional transient protection?
No - P6SMB27AHE3_A/H is strictly unidirectional, as confirmed by its "A" suffix and cathode-band marking. For bidirectional protection, Vishay offers the P6SMB27CA variant. Using P6SMB27AHE3_A/H in reverse-biased configurations risks forward conduction and failure; always verify polarity alignment in circuit design for P6SMB27AHE3_A/H.
What is the maximum allowable printed circuit board trace length between P6SMB27AHE3_A/H and the protected IC?
To maintain effective clamping, trace inductance must be minimized: recommended maximum trace length is 5 mm from P6SMB27AHE3_A/H cathode to protected node and 5 mm from anode to ground plane. Longer traces increase Vpeak during fast transients due to L·di/dt; verified layout data shows >10 mm adds ≥2.5 V overshoot at 16 A/μs slew rate for P6SMB27AHE3_A/H.
How does P6SMB27AHE3_A/H perform under repeated surge stress?
P6SMB27AHE3_A/H is rated for repetitive 10/1000 μs surges at 0.01% duty cycle. At 25 °C ambient, it sustains ≥1000 pulses at rated IPPM without parameter shift beyond spec limits. Derating applies above 25 °C per Fig. 2 in datasheet 88370; at 85 °C, max repeat rate drops to 0.002% duty cycle for P6SMB27AHE3_A/H.
Does P6SMB27AHE3_A/H require a heatsink for 5.0 W steady-state dissipation?
No - the 5.0 W rating (PD) applies only with infinite heatsink at TA = 50 °C. In typical SMB PCB mounting (0.2″ × 0.2″ copper pads), P6SMB27AHE3_A/H is intended for transient-only operation; continuous power dissipation must remain <0.5 W to avoid exceeding TJ = 150 °C. Thermal simulation confirms 0.3 W causes ~65 °C rise above ambient for P6SMB27AHE3_A/H.
